"dec"ember used to be the 10th month which puts old new years at the beginning of march, a few weeks before the equinox. also, i haven't even noodled this in my head much but I think it works out in which direction it slips the date (hmmm maybe not), but it wasn't till Pope Gregory that it was realized there was a 100 year non leap year problem serious enough to impact the calendar.
