Just when you think you know what day it is, along comes this research on the ancient Mayan calendar.
By fifth grade, most schoolchildren know that a week contains seven days, a month contains either 30 or 31 days (or 28 days, in those strange “leap years”), and a year contains 12 months and 365 days.
That seems self-evident, right?
