Though I am not sure this belongs in the Math category:
We have 12 months in a year because at one point or another we had a calendar based on the lunar cycle (28.5 days, the time from one full moon to the next), in an attempt to combine this with the solar cycle (~364.25 days, time to go around the sun) we added months, which are approximately the length of a lunar cycle. You might want to check sources on the following information, but in my research, I recall learning that a Central or Southern American tribe used to have 13 months, the first 12 being 28 or 29 day, and the last month being the remainder of the year.

What is the probability that a randomly chosen month has 30 days?
there are 4 monthes that has 30 days each year there are 12 monthes each year. so the probabillity for picking a month that has 30 days in it is 4/12
How many years is 10000000000 monthes?
dont u kno maths? 1 year=12 months sooo.... 10000000000/12=?? use a calculator
Why was there used to be 10 monthes in a year?
In the ancient Roman calendar December (which means 10th) was the final month of the year and it was Julius Caesar who introduced the 12 month calendar known as the Julian Calendar.
How many monthes are there in 20 years?
Twelve months in one year multiplied by 20 equals 240 months.
Is it spelled monthes or months?
The correct spelling is month, without an E.
