# On Augustus' Actual Prescription to Restore the Julian Calendar to Accuracy

I hope that I may ask this question here as I have seen some favorably received questions related to the Julian calendar on this site.

From James Evans' book, The History and Practice of Ancient Astronomy,'' is the following snippet (pg. 165):

In praticular, it indicates that to bring the [Julian] calendar back into step with the original plan, Augustus decreed in 8 B.C. that all intercalations be omitted until A.D. 8.''

I know the Romans were inclusive'' counters---so may I interpret this as meaning that leap years did not resume until 12 A.D.?

Another source: https://www.tondering.dk/claus/cal/julian.php specifically states: There were no leap years between 9 BC and AD 8 (or, according to some authorities, between 12 BC and Ad 4).''

QUESTION: Does anyone know for certain if A.D. 8 was a leap year or not; and would you please provide an authoritative reference if you know of one?

Thank you.
