《晋书·志·第八章》
以朔望合敷六万七千三百一十五各加当月合朔时的去交度分，满会通则除去，余下的为当月望时的去交度分。
以朔望合数各加其月合朔去交度分，满会通去之，余则各其月望去交度分也。
Adding 67315 to the conjunction of the Sun and the Moon of each month, plus the conjunction degree and minute of the Sun and the Moon of the lunar eclipse, removing any numbers over 790000, would equal the conjunction degree and minute of the full Moon of that particular month.
