Why are months as long as they are?

As a result, the earliest ancient Roman calendars had months that were either 29 or 30 days. Julius Caesar modified the Roman calendar in 46 B.C. to make each month have either 30 or 31 days, with the exception of Februarius, which had 29 days and gained an extra day every fourth year.

Similarly one may ask, why are months different lengths?

The reason that some months are longer than others is that to make their months longer, they took months from other days. So July and August are both 31 days, while others are shorter.

Likewise, how did they decide how many days in a month? Julius Caesar reformed this Roman calendar of Numa and brought Julian calendar into the picture. Ten days were added to the pre-Julian Roman year of 355 days. Julian months were created by adding 2 extra days to January, Sextilis (August) and December, and one extra day was added to April, June, September and November.

Additionally, why do some months only have 30 days?

The thing is that originally the months alternated with 29 or 30 days to compliment the lunar (moon) cycle. However, the year was a solar (sun) year, and thus days were added to each month to increase this so that the two coincided.

Why are there 12 months in a year instead of 13?
