I’d always heard that it was because the ancient sumarrians thought there were 360 days in a year combined with the fact that their holy number was 60 so it divided cleanly.
It takes only about 19 years for a 360 day calendar to be off by a whole season. Every ~38 years, winter and summer would swap entirely. Grandparents would have told their grandchildren about how much easier the summers were and how much harder the winters were.

I doubt the ancient Sumerians thought there were 360 days in a year.
