And it's wrong. The email is from 1997, but now you can look it up on wikipedia: http://en.wikipedia.org/wiki/Julian_calendar Short version - Julius didn't name the month after himself, the roman Senate did. There's good indications that July and August had 31 days before the reform, and February has less days because it was the last month of the year.

I have thought February would make more sense as the last month of the year. But I guess that's because I live in the Northern Hemisphere and having the year start right after Winter starts seems like a bad combination.

To me, the most mathematically logical way to split up the calendar would have just been something like: 01 02 03 04 05 06 07 08 09 10 11 12 31 30 31 30 31 30 30 31 30 31 30 30 -- common year 31 30 31 30 31 30 30 31 30 31 30 31 -- leap year - All months 30 or 31. - Leap month alternates between 30 and 31. - Never have more than two consecutive months with the same day. - Only time two consecutive months have the same…

Surely it would also make more sense to start with 30 and alternate, rather than having months 6 and 7 both be 30? Then it almost fits an alternating pattern, with only one weird month to worry about.

This is close to what was done, February is the last month of the year in the Julian calendar. Only two consecutive months have the same amount of days (July/June) and the last month varies by leap year (adding an extra day at the end of the year)

It's only weird that the last month got 28 due to doubling of the 31 day months instead of 30 day months

Problem is you would end up w/ three months of 30 days during common years.

This is a cute story, but it lacks all sources, and it contradicts Wikipedia [1] [2]: > Commonly repeated lore has it that August has 31 days because Augustus wanted his month to match the length of Julius Caesar's July, but this is an invention of the 13th century scholar Johannes de Sacrobosco. Sextilis in fact had 31 days before it was renamed, and it was not chosen for its length (see Julian calendar). According…

Contradicting Wikipedia does not equal a lack of truth.
