《晋书·志·第八章》
日食发生在朔日，这是符合自然的规律，《经》、《传》上又写着，朔日食，可以称为得天，而刘、买等各人的学说，都认为日食可在月初二或初三发生，公然违背圣人的明文，他们的弊端在于，衹认定一个上元，而不根据实际天象进行改正。
日蚀于朔，此乃天验，《经传》又书其朔蚀，可谓得天，而刘贾诸儒说，皆以为月二日或三日，公违圣人明文，其弊在于守一元，不与天消息也。
Solar eclipses occur on the day of the first new moon, and this is in accordance with the natural laws; the Classics and Commentaries also state that a solar eclipse on the first new moon can be described as obtaining Heaven. However, the doctrines of Liu, Mai and others all hold that solar eclipses can occur on the second or third day of the month, which brazenly violates the clear text of the sages. The flaw in their approach is that they only recognize one Shangyuan (the first day of a quarter of the year), and do not adjust their theories in accordance with the actual astronomical phenomena.
