Why don't all months have same number of days?
That's really interesting. So does that mean February was always selected to have fewer days?
Yes, that's correct. February was originally the last month of the calendar, and it had 28 days. However, when the two new months were added, it was moved to the middle of the year and shortened to 28 or 29 days, depending on whether it was a leap year or not.
