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.

When the hour was divided into 60 minutes, consisting of 60 seconds, the number 60 was probably chosen for its mathematical convenience. It is divisible by a large number of smaller numbers without a remainder.
