Question

Why are there 12 months in a year?

Answer 1

The length of a year is determined by how long it takes for the earth to complete it's orbit around the sun (365 1/4 days).

The moon orbits around the earth about every 29 days - that's a lunar month.  If you divide 365 1/4 days by 29 days, you get about 12 1/2 lunar months in a year.  So to have an even number of months in the year, days were added to some of the 12 months to get us to the 365 days (366 in leap years) so that we would have an even 12 months (calendar months) in a year.

Answer 2

cuz i told it to be that way.

Answer 3

Because people have an aversion to the number 13, which would make more sense to have divided the year up into.

Answer 4

They use the Gregorian calender, which divided the four seasons into 3 months each. It was also based on lunar and solar cycles. Everyone had their own version, but most had 12 months. The Gregorian calender is the one that everybody uses, and it has 12 months.

Answer 8

It dates from the romans.

The first 12 month calendar was the Roman calendar, although it originally consisted of only 10 months.  This calendar was short by 61 days so around 713 BC, Numa Pompilius added two months to the end

of the calendar.  You may never have guessed that those two extra months were January and February.  This calendar was still off from the Gregorian calendar that we use today, for one the months only had 29 days in them.  After Numa Pompilius changed the calendar there were 355 days in a year, still 10 days off but much better than 61 days off.

In order to keep the seasons from shifting dramatically and confusing the animals there were occasionally leap years, just like ours (sort of).  Instead of adding one day in February, an entire month as added.  This leap month was known as Mercedonius.   For some strange reason during a leap year February (known then as Februarius) was shortened to 23 or 24 days, the leap month began at the end of Februarius.

The months of January and February were added to the calendar and the original fifth and sixth months were renamed July and August in honour of Julius Caesar and his successor Augustus.

These months were both given 31 days to reflect their importance, having been named after Roman leaders.
