After Emperor Xianzong came to the throne, Xu Ang of the Astronomical Bureau submitted a new calendar called Observing Phenomena (Guanxiang). It was put into use from the second year of Yuanhe (807), but it lacked obscuration-cycle parameters. For fixing the seasons of gathering-in and opening-and-closing, the calendar still followed older methods, and observational tests failed to match. When Emperor Muzong acceded, holding that a dynasty continuing its line through successive reigns must renew its calendar era, he ordered the court astronomers to draft new calendrical methods, named Illuminating (Xuanming). At the high origin, the seven luminaries start at 9° of Xū on the celestial equator. Its procedures for central qi, new moons, solstitial timing, solar motion, and lunar motion all followed the old Dayan methods; while gnomon-clepsydra and syzygy parameters were adjusted slightly; and new constants were set to compute the five planets. Its general outline reads:

The universal divisor is termed the cycle constant. The divination solid is termed the chapter years. The stalking method is termed the chapter months. The hanging limit is termed the intercalation limit. The three-origin divination is termed the central node. The four-images divination is termed the combined divination. The one-image divination is termed the image standard. The divination remainder is termed the universal remainder. The line number is termed the cycle method. The universal cycle method taken as parts is called the ten-day cycle. Chapter years multiplied by the year-count yield the accumulated universal parts. The divination at the earth's center is termed the period divination. The divination at heaven's center is termed the hexagram divination. Subtract the central node from the true-and-false divination to obtain the chronogram number. Add this to the solar term of the last month of the season, and the result is the day on which Earth takes dominion. Whenever minor remainders fill the chronogram divisor, they form the chronogram number; when they fill the quarter-hour divisor, they form quarter-hours. The Qian solid is termed the image number. The second divisor is 300. Multiply the cycle constant by this to obtain the divided cycle.

In computing the seven luminaries' entry into lodge degrees, the quarter-hour divisor serves as the degree mother throughout. The quarter-hour divisor multiplied by the surplus-deficit parts, divided once per fixed qi, yields the central qi rate. Subtract this from the following qi's central rate to obtain the combined difference. Multiply the combined difference by the fixed qi, add the following fixed qi as divisor, and divide to obtain the central difference. Add or subtract the qi rate to obtain the initial and final rates. Double the central difference, multiply by 100, divide by the fixed qi, and obtain the daily difference. Halve this value, add or subtract it from the initial and final rates, and each becomes a fixed rate. Accumulate the daily difference by repeated addition and subtraction to obtain each day's surplus-deficit parts. Multiply the before-and-after qi descent count by 100, first subtract then add the regular qi, and obtain the fixed-qi limit number. Multiply the annual discrepancy by 1,440 to obtain second-parts. Add this to the central node; starting from the winter solstice yellow-path solar degree, accumulate and trim to obtain the initial solar degree for each fixed qi.

Entry into rotation is termed the ephemeris. Whenever entering the ephemeris, if at or below the ephemeris midpoint it counts as advance; if above, subtract the excess, and that counts as retreat. For fixed new-moon minor remainders after the autumn equinox, if three-fourths or more, advance the date by one day. After the spring equinox, when twilight minor remainders differ from the spring equinox initial day, take one-fifth at a time to reduce the three-fourths threshold. If the fixed new-moon minor remainder reaches this number or higher, advance the date by one day. If a conjunction occurs and the initial phase of waning should be visible, then do not advance. If the fixed first- or full-moon minor remainder does not reach the twilight minor remainder, retreat the date by one day. If a conjunction occurs and the initial waning should be visible, the same rule applies. For the true crossing, take the waxing-and-waning fixed number of the mean crossing's entry into the ephemeris; waxing subtracts and waning adds from the mean crossing's entry into the fixed-qi remainder; if the result overflows or falls short, adjust the day count forward or back to obtain the true crossing's entry into fixed qi—without again multiplying by the crossing rate, dividing by the crossing number, or adding and subtracting the mean crossing's waxing-and-waning in qi.
5
To compute the lunar phase, multiply the ephemeris parts by the fixed full clepsydra at midnight, divide once by the quarter-hour divisor, and obtain the dawn parts; subtract this from the ephemeris parts to obtain the dusk parts. Multiply the fixed new-, first-, and full-moon minor remainders by the ephemeris parts, divide by the cycle constant, subtract from the dawn parts, and the remainder is the before portion; if insufficient, reverse the subtraction instead, and the remainder is the after portion. Add the before portion and subtract the after portion from the hour-addition lunar phase to obtain the dawn and dusk lunar phases. Subtract the following ephemeris's hour-addition solar degree from the current entry's hour-addition solar degree, add the remainder to the first-quarter degree and its remainder, subtract before the entry day and add after as required, and likewise add before and subtract after on the following ephemeris—each yielding a fixed course. Then accumulate the daily ephemeris degrees and parts from the distance to the following ephemeris and subtract from the fixed course; if positive, that is surplus; if insufficient, reverse the subtraction instead, and that is deficit. Spread the difference evenly over the days to the following ephemeris; subtract surplus and add deficit to each day's ephemeris parts to obtain the fixed ephemeris parts. Accumulate these to the new-, first-, and full-moon dawn and dusk lunar phases to obtain each day's dawn and dusk lunar phases, without further adding or subtracting waxing and waning.
6
The line cycle is termed the central cycle. The image accumulation is termed the quarter-hour divisor. Increase-and-decrease is termed waxing-and-waning. Align surplus-deficit parts by waxing-and-waning, find each day's entry, and term it the fixed decline. Multiply by five, divide by twenty-four, and obtain the clepsydra difference. Add waning and subtract waxing from the initial qi midnight clepsydra to obtain each day's fixed midnight clepsydra. The quarter-hour divisor expressed as parts is termed the twilight minor remainder. Multiply the waxing-and-waning fixed number by 21 and divide by 25 to obtain the yellow-path waxing-and-waning difference. Subtract waning and add waxing from the initial qi's distance-from-pole parts to obtain each day's distance-from-pole parts. Multiply the yellow-path waxing-and-waning difference by 12,386 and divide by 16,277 to obtain the daily degree difference. Subtract waning and add waxing from the initial qi's mid-distance parts to obtain each day's mid-distance count. Waxing-and-waning aligned to increase-and-decrease at the midday gnomon shadow is termed the fixed number; for clepsydra quarter-hours, the clepsydra difference; for distance from the pole, the waxing-and-waning difference; for mid-distance, the degree difference.
7
Crossing completion is termed the completion rate. The new-moon difference is termed the crossing new moon. The full-moon number is termed the crossing full moon. The crossing limit is termed the forward standard. The full-moon difference is termed the rear standard. Whenever the moon's motion enters the four-images yin-yang degrees with fractional parts, multiply by 10, divide by 7, and obtain degree-parts. If a remainder remains, multiply by 15, divide by 7, and obtain major parts. If still not exhausted, divide again to obtain minor parts. Then divide by the 90° of one image, also dividing out degree-difference parts 113, major parts 7, and minor parts 1 slightly less, and then divide successively by each image.
8
For solar eclipses, take the fixed new-moon day's chronogram quarter-hours of sunrise and sunset relative to noon standard quarter-hours, reduce by approximately 147, and obtain the time difference. If the fixed new-moon minor remainder is at or below half the divisor, subtract it from the half divisor to obtain the initial rate; if above, subtract the half divisor; the remainder is the final rate. Multiply by the time difference and divide once by the quarter-hour divisor; subtract with the initial rate, double the final rate and add to the fixed new-moon minor remainder, and obtain the eclipse fixed remainder. For lunar eclipses, the fixed full-moon minor remainder serves as the eclipse fixed remainder.
9
Solar eclipses involve qi difference, quarter-hour difference, and additive difference. At the start of the two solstices, the qi difference is 2,350. Moving away from the solstices before and after, decrease by 26 each day until the equinoxes, when it reaches zero. Take the chronogram quarter-hours of sunrise and sunset relative to noon, approximate the new-moon day's qi difference, and multiply by the greatest eclipse's distance from noon standard quarter-hours. Subtract the product from the qi difference to obtain the fixed number. After the spring equinox, add for yin months and subtract for yang months; after the autumn equinox, subtract for yin months and add for yang months.
10
On the first day of each solstice, there is no quarter-hour difference. Thereafter the difference increases each day by 2 parts and 10 minor parts. From Beginning of Spring to Beginning of Summer, and from Beginning of Autumn to Beginning of Winter, the quarter-hour difference is set at 94½ parts. Thereafter decrease the difference by 2 parts and 10 minor parts each day until it is exhausted at the next solstice. Multiply the new-moon day's quarter-hour difference by the greatest eclipse's distance from noon standard quarter-hours to obtain the fixed quarter-hour difference. After the winter solstice, if greatest eclipse falls before noon standard, and after the summer solstice if it falls after noon standard, subtract for yin months and add for yang months; After the winter solstice, if greatest eclipse falls after noon standard, and after the summer solstice if it falls before noon standard, add for yin months and subtract for yang months.
11
After the first day of Start of Winter, increase the difference by 17 for each qi. By the first day of the winter solstice, it reaches 51. Thereafter decrease by 17 for each qi until Great Cold, when it is fully exhausted. If greatest eclipse falls after noon standard, cumulatively increase the difference for each quarter-hour; subtract for yin months and add for yang months. For the applicable add-subtract differences, combine matching signs and cancel opposite signs; each result is an eclipse correction. Add or subtract from the distance from conjunction to obtain the fixed fraction. When the moon is in a yin month, if subtraction is insufficient, subtract the eclipse correction in reverse. Subtract before conjunction; the remainder is the yang-month fixed fraction after conjunction; subtract after conjunction; the remainder is the yang-month fixed fraction before conjunction: in neither case is there an eclipse. When in a yang month subtraction is insufficient, likewise subtract the eclipse correction in reverse. Subtract before conjunction; the remainder is the yin-month fixed fraction after conjunction; subtract after conjunction; the remainder is the yin-month fixed fraction before conjunction: in both cases there is an eclipse.
12
In general, for the fixed distance from conjunction, if it is at or below the yang-month eclipse limit, the eclipse is a yang-month eclipse. Reduce by the yang-month fixed divisor to obtain the eclipse magnitude. If above, subtract the yang-month eclipse limit; the remainder is a yin-month eclipse. Reduce by the yin-month fixed divisor, subtract from 15, and the remainder is the eclipse magnitude.

For lunar eclipses, when the distance from conjunction is 2,147 or less, the eclipse is total in every case. If above, subtract the posterior criterion; divide the remainder by fixed divisor 506 to obtain the eclipse magnitude. For total lunar eclipses, use 20 provisional quarter-hours throughout. If the distance from conjunction is 1,435 or less, add an additional half quarter-hour. If it is 712 or less, add another half quarter-hour. For solar and lunar grazing eclipses at rising and setting, convert each eclipse magnitude through the fixed divisor, divide by half the fixed applicable quarter-hours, and multiply by the visible quarter-hours. If the result exceeds half the fixed applicable quarter-hours, emergence counts as advance and setting as retreat. If it is less than half the fixed applicable quarter-hours, emergence counts as retreat and setting as advance. Divide each once by the fixed divisor to obtain the major fraction of visible eclipse. For new moons in daylight and full moons at night, both use visible quarter-hours. For eclipse corrections in the nine domains, no further detailed examination is made.

The five planets' terminal rate is termed the cycle rate. Add middle hiding to mean conjunction to obtain mean appearance. For Venus and Mercury, add evening visibility to obtain morning visibility; add morning visibility to obtain evening visibility. Also multiply the mutation difference by the year-count and cast out full image numbers; the remainder is the mutation crossing. Reduce to parts by 300, divide once by the cycle constant, and subtract from mean appearance. Multiply mean appearance seconds by 36 and mutation crossing seconds by 12, with 3,600 as the common denominator. If the remainder is at or below the crossing rate, the planet is in the yang half; if above, discard it; the remainder is entry into the yin half. Divide each by the mutation divination to obtain the mutation count, counting from outside the initial mutation tally; the remainder is entry into its mutation degree-count and remainder. From this point, reduce the remainder parts by 100; the denominator matches the quarter-hour divisor. Add or subtract from mean appearance by the number below for the mutation entered to obtain regular appearance. For Venus morning appearance, first compute from evening appearance through all evening retrograde, applying the prior-posterior differences to be added or subtracted. Where signs match, combine; where they differ, cancel. With the morning regular appearance add-subtract difference, cancel opposite signs and combine matching signs. Accordingly add or subtract from morning mean appearance to obtain regular appearance.

In general, set regular appearance against fixed qi, find the prior-posterior fixed numbers, multiply each by the difference rate and divide once by the difference number, and obtain the fixed difference. For morning appearance subtract first and add later; for evening appearance add first and subtract later from regular appearance to obtain fixed appearance. Use the add-subtract amounts of regular appearance and fixed appearance to adjust mean appearance's entered mutation degree-count and remainder seconds, obtaining the initial mutation entered at fixed appearance. Add for direct motion and subtract for retrograde by the degrees traveled; that is the next mutation entered. For each, add or subtract the difference number below the mutation entered to the daily-degree phase rate. For Mercury, the add-subtract amounts of regular appearance and fixed appearance combine matching signs, cancel opposite signs, and reverse the additions and subtractions. When evening appearance's difference adds to the swift-motion day rate, double the difference and add to the degree rate. Also divide the difference and add to the slow-and-stationary day rate. For morning appearance likewise divide the difference and add to the slow-and-stationary day rate; add the difference amount to the swift-motion day rate, double the difference, and add to the swift-motion degree rate. When evening appearance's difference subtracts from the swift-motion day rate, double the difference and subtract from the degree rate. Also subtract the difference from station days; if insufficient, encroach and subtract from slow days. When morning appearance's difference subtracts from station days, if insufficient encroach and subtract from slow days; also subtract the difference from the swift-motion day rate, double the difference, and subtract from the degree rate. The prior-posterior numbers of the first day of the prior mutation and the last day of the posterior mutation cancel matching signs and combine opposite signs to obtain the prior-posterior fixed number. Multiply each by the difference rate and divide once by the difference number to obtain the day difference. Venus uses the posterior mutation's difference rate and difference number. Subtract the prior-posterior fixed number to obtain the degree difference. For Venus evening hiding, subtract the day difference from the prior-posterior fixed number to obtain the degree difference. For morning hiding, add the day difference to the prior-posterior fixed number to obtain the degree difference. For Mercury evening hiding, take the prior-posterior fixed number as the day difference. Double it to obtain the degree difference. Then with the day-degree difference, subtract where surplus has accumulated and add where deficit has accumulated to the final mutation's daily-degree rate. For Venus and Mercury morning hiding, reverse the application of the difference. Also double the retrograde difference, multiply by the difference rate, divide once by the difference number, and obtain the day difference. Subtract the retrograde difference to obtain the degree difference. For Venus evening hiding, subtract the retrograde difference from the day difference to obtain the degree difference. For morning hiding, add the retrograde difference to the day difference to obtain the degree difference. Where the retrograde day-degree difference should add, subtract from the final mutation's daily-degree rate. For morning hiding, reverse the application of the difference. After all add-subtract adjustments to the phase rates, the result is the fixed daily-degree rate.
16
All else likewise follows the Dayan Calendar methods. Where parts and seconds differ, each follows its own calendar's base divisors.
17
Beginning in the second year of Changqing, the Illuminating Calendar was used. From Emperor Jingzong through Emperor Xizong, all adhered to it. Though the court faced many troubles and lacked leisure for revision, among calendars after the Dayan it was the simplest in method and the closest in matching conjunctions and full moons, and none could surpass it. This continued until the first year of Jingfu.
18
The Observing Phenomena Calendar is no longer transmitted among the current officials.

1324
便
Under Emperor Zhaozong the Xuanming Calendar had been in force so long its figures had drifted; the throne ordered Bian Gang, Hu Xiulin, and Wang Chi to compile a new calendar, though the techniques all issued from Gang. Gang was deft with reckoning and moved freely through multiply-and-divide operations. Shortcut, super-direct, and equal-joining methods then arose, while canonical regulation, far magnitude, and ordered decline were set aside. Rod reckoning was easier, yet all lost sight of the root principle. Its upper origin for the seven luminaries starts at equatorial Xū 4°. In Jingfu year 1 the calendar was finished and named Chongxuan. Qi, new moons, issuing-and-gathering-in, surplus-deficit, waxing-and-waning, fixed syzygies, nine-path lunar position, conjunctions, and eclipse limits all follow Dayan. The rest differs, yet the same end is reached by another route. In broad outline:
1325
Divination solid → year solid. Stalk method → new-moon solid. Three-origins divination → qi divination. Four-images divination → mean conjunction. One-image divination → quarter divination. The hanging limit is termed the intercalation limit. The line number is termed the cycle method. Divination remainder → year remainder. Heaven-center divination → hou divination. Earth-center divination → hexagram divination. True-and-changing divination → earth-kingship divination. The chen method is half the chen method. Qian solid → circuit-of-heaven parts. Surplus-deficit and waxing-and-waning all use regular qi. Surplus-deficit parts → ascent/descent. Prior and posterior → surplus-deficit.
1326
For ascent-descent and decrease-increase, advance one rank, double the image tally, divide once—mean rate. Subtract from the posterior rate for the difference. Halve it; add or subtract to the mean rate for initial and final rates. Double the difference, advance one rank, multiply by the image tally, divide once for the daily difference. Add and subtract initial and final for the fixed value. Accumulate daily difference add/subtract for daily parts. For all minor remainders, multiply by 10,000; divide by the common divisor for reduced remainder, with 10,000 as divisor. Also reduce by 100 for major parts, with 100 as divisor.
1327
宿宿 滿 退 退 宿
From winter-solstice equatorial degree and reduced remainder, subtract lodge full degrees and accumulate successive lodges for post-distance accumulation. When it fills the limit 91°31′37″, remove it. Remainder at or below half: initial; if above, subtract from the limit for final. All ×144, retreat one rank, subtract 1,315. Multiply initial and final degree-parts by the result for the difference. Convert initial and final degree-parts; subtract then multiply with 4,566, divide by 1,690 to subtract from the difference for fixed difference, retreat again for parts. After solstice subtract; after equinox add to post-distance accumulation for yellow-path accumulation. Subtract successive lodges for the degree.
1328
宿宿
From winter-solstice equatorial degree and reduced remainder, subtract the fixed difference as before for yellow-path solar degree. Precession: ×11, also × the qi sought, ÷3,888, add to prior qi central accumulation; Add surplus and subtract deficit from surplus-deficit parts; count from winter-solstice lodge for qi initial added-time lodge degree.
1329
If fixed-new-moon minor remainder ≥ 29/40 of the day divisor, subtract the day divisor; if remainder ≤ morning-initial remainder, advance one day.
1330
滿
Gang also used a direct method to find yellow-path monthly degree. Remove obscuration rate from accumulated years for obscuration cycles. The remainder is obscuration remainder. Multiply obscuration remainder by year remainder and set aside. Double obscuration cycles, divide by 37, subtract from aside. Reduce obscuration remainder by 119 and add to the aside. Remove what fills the circuit of heaven. Remainder: ×4 for parts; ÷ degree mother once for degrees—winter-solstice added-time mean Moon.
1331
Winter-solstice reduced remainder noon distance ×254; ÷10,000 for parts; degree mother for degrees; Before noon add, after noon subtract from added-time Moon for noon-center Moon. From here count days: mean motion 13° 7′. From winter solstice to fixed new moon, accumulate subtracting mean motion for fixed-new-moon noon-center Moon. For next new moon and quarters, count days and add mean motion. Divide parts by the degree mother for reduced parts.
1332
退 滿
Also divide obscuration remainder by 47 for rate difference. Remainder × 7 days 3½ parts; set aside. 9 × rate difference, retreat one rank for parts, subtract from aside. Reduce winter-solstice added-time noon distance by 100; before noon add, after noon subtract; remove rotation cycle for winter-solstice noon-center entering rotation. Subtract winter-solstice-to-new-moon days for fixed-new-moon noon-center entering rotation. For next new moon and quarters, count days and add.
1333
滿
Each day: rotation remainder × that day's decrease-increase rate ÷100; adjust surplus-deficit accumulation for fixed difference. Add surplus and subtract deficit to noon-center Moon for fixed Moon. Fixed lunar motion × morning/evening noon distance ÷10,000; ÷100 for degrees; subtract from noon fixed Moon for morning Moon; Add for evening Moon.
1334
Differences between syzygy/quarter evening and morning Moons give each fixed interval. Average interval days for mean motion degree-parts. Subtract the next interval for the difference. Add and subtract to mean motion for initial- and final-day fixed motion. If the next is smaller, add initial and subtract final. If the next is larger, subtract initial and add final. Subtract one from interval days; average the difference for daily difference. Accumulate decrease and increase from day one for daily fixed motion. If the next is larger, accumulate increase. If the next is smaller, accumulate decrease. From syzygy/quarter morning and evening Moons, accumulate to daily morning and evening Moons.

For each, count days and remainder from solstice added time to that day's noon. At or below the initial limit: posterior; if above, subtract from solstice limit; remainder is anterior—set aside. Multiply each by its multiplier to subtract initial and final differences. Multiply again by the aside; one million fills a chi; remainder is cun and fen. After summer solstice, retreat one rank. All are named gnomon difference. Before and after each solstice, subtract from winter-solstice noon gnomon; before and after summer solstice, add to summer-solstice noon gnomon: daily Yang-city noon gnomon. Subtract the next day; larger next: breath-increase; smaller: breath-decrease. × solstice before/after-noon reduced parts ÷10,000; before/after noon rules on breath and gnomon for fixed number.

Nine-domain mid-gnomon: set up the gnomon and observe at each place. North of Yang-city, before winter solstice when the shadow matches Yang-city winter solstice: difference-day start; South of Yang-city, before summer solstice when the shadow matches Yang-city summer solstice: difference-day start. From difference-day start to solstice: days from difference. Before solstice: count days since prior distance; After solstice: count days since entering after solstice. Inversely subtract distance-difference days; remainder is post-distance day standard. Seek initial/final limit gnomon differences: add/subtract Yang-city solstice noon gnomons for local noon gnomon. If insufficient, subtract from summer-solstice Yang-city noon gnomon for south-inverted noon gnomon. Other days: count days after the solstice sought. Subtract distance-from-solstice difference days; remainder enters initial/final limits. At each nine-domain location, set a water clepsydra to fix solstice night quarter-hours as clepsydra rate.
