1 HM year = 381.3668618 Earth days

357.0806527870906 days (ratio)

good for a 7 day week

357 = 51*7 leap day every 12.3988275678 years

months: 30 30 30 29 30 30 30 29 30 30 30 29(30)

every 12 except: when the year is divisible by 372 perfect for clofabians

so the years 270, 520, 790, X40, 10E0, 1360, 1610, 1880, ... are not leap years

actually if the year is divisible by 130944=352*372 it's a leap year
