There are 180 months in 15 years, and just in case you were wondering, that's 5,478 days.
There are 12 months in a year, so to find the total number of months in 15 years, you would multiply 15 by 12. This calculation gives you 180 months in 15 years.

15 years
If you assume that each generation had a child at the age of 18 and the eldest was 90 years old, then there would be 6 generations at the reunion. This can be greater if the eldest is older than 90 and each generation had a child earlier than 18. For example there would be 7 generations at the reunion if the eldest was still 90 and each generation had a child at 15 years of age.
30 years. 15 - -15 = 15 + 15 = 30.
10 years??30 years I believe, from -15 to +15 is 30
15 years = 131,487.192 hours.
