The idea of months began as "Moon Cycles"... and thus the term Months from the word Moon.
A lunar month, however has 29.53 days, and a solar year has 365.242 days...
So the seasons would shift slowly with calendars based on 12 lunar months (and you would still have either 29 of 30 day months to compensate for fractional days in the lunar cycles).
But, perhaps because the moon (lunar) cycles were previously used, 12 months were chosen for the calendar.
365 days / 12 months = 30.416 days.
Thus to divide a year into 12 calendar months with full days (fractional days don't work), the number of days per month have to be varied slightly.
The approximately quarter day per year "extra" is compensated for by adding an extra day every 4 years on the leap year, with more complicated rules to compensate every century
Also see the Wikipedia articles on the Tropical Year that our calendar is based on, and the Sidereal Year which the procession of the equinoxes is based on.

Why do the months of a year have different lengths?
Original calendars measured the year by dividing it into months. That number of days was based on the cycle of the Moon, which lasts about 29 and one-half days. Months in different cultures ranged from 28 to 31 days, As the year, based on the Sun, is about 365 days, the months could not all have the same number of days. 365 is not divisible by 28, 29, 30, or 31, so naturally some months had to have different amounts of days. Different cultures came up with different ways of naming their months and giving them their lengths.
