Our calendar is based on the old Roman Calendar consisting of ten months of 30 days each. Augustus was advised that the calendar was off, and needed two more months--he added one for himself, and one for his uncle Julius. Later it was found to be still off, and days were deducted from February to augment several other months. The Church (at that time there was only one) realized that the months were slipping off schedule at the rate of one day about every 4 years. On the fourth year, a day was added to February to 'leap forward' and catch up to the seasons. One more major adjustment in the early Middle Ages, and the calendar was ready to fly. B.

there are a lot of ways to make a calendar. We decided to make a calendar that matched the "solar year" which is 365.25 days (approximately).
We could have decided to make a 100 days year, if we wanted, but it would have been weird : winter and summer would have moved from year to year... never the same date...
the calendar is a convention: we decided on it because we liked the way it was. Therefore, there's no real reason...
BUT: we made a calendar that has months of approximately 1 lunar cycle, and weeks of 1/4 of a lunar cycle...
hope this helps.

So the full year calendar matches the rotation of the earth around the sun. If the months were equal, we would have fractional days on the calendar. I think.

Bcos sometimes the moon might move and stop at apoint which shows the end of that month, So they dont have the same days bcos the movement is not the same.

Because the months are determined by like the Earth's rotation and the moon and stuff, right? So it just doesn't work that way, and it would be really boring too, I mean, then there would be no leap years or anything and it just wouldn't be fun.

because no month should have 30.416666666 days in it. Do the math 365 divide 12 equals 30.4166666666

Because our calender is quite inaccurate. Besides, 365/12 is 30.42. How would you like to have one day be in two months?

you need to get the planet to cooperate and rotate an even number of times to make a even dayed year.
