43. Other times

Enuma Anu Enlil and MUL.APIN are two sizable compendiums of astronomical records and related texts. Historians date the records mostly to the centuries and millennia before 747 BC. But like the Venus Tablet, the observations do not tally with conventional computations. Their primary purpose may be divinatory rather than astronomical, or as some historians hold, the observations may simply be crude.

The compendiums draw on an ideal calendar that rounds off the year to 360 days and the month to 30 days. If early Babylonian astronomy were based on an inaccurate month and year, then standard calculations would be ineffective in dating the observations recorded in the ancient documentation.
