由是占候漸差，乃命司天監趙知微重修《大明曆》，十一年曆成。 Prognostication and observation drifted apart; Zhao Zhiwei, Director of the Astronomical Directorate, was therefore ordered to revise the Grand Clarity Calendar, and in the eleventh year the calendar was completed.

二十一年十一月望，太陰虧食，遂命尚書省委禮部員外郎任忠傑與司天曆官驗所食時刻分秒，比校知微、履及見行曆之親疏，以知微曆為親，遂用之。 In year 21, at the full moon of the eleventh month, the moon was eclipsed; the Ministry ordered Ren Zhongjie of the Rites Bureau and the calendar officers to verify the hour, minute, and second of the eclipse and compare Zhao Zhiwei's, Yelü Lü's, and the current calendar—Zhiwei's proved closer, and his calendar was adopted.

是以終金之世，惟用知微曆，我朝初亦用之，後始改《授時曆》焉。 Through the whole Jin age only Zhao Zhiwei's calendar was used; our dynasty used it at first as well, then replaced it with the Season-Granting Calendar.
