Great month. Are you aware that in the past, new years day used to be March 1'st? That's kind of why the number of days in a month are as they are and the last month of the year has the remaining days.
But Augustus Caesar had bolluxed this a bit.
It should be March-April-...-December-January-February with 31-30-31-30-31-30-31-30-31-30-31-29
but he couldn't only have 30 while Julius had 31 so it's:
31-30-31-30-31-31-30-31-30-31-(31)-28
I'm not sure why January has 31, perhaps since it's two-faced?
