Best Answer

A month isn't a set number of hours, since its days range from 28 to 31. So you have to find an average month. An average year is 365.25 days long (since we have leap years every four years), so an average month is 365.25 / 12 which is 30.4375 days. Since a day has 24 hours, an average month is 730.5 hours, so 90 months is 65,745 hours.

This is only for an average month though, so it really depends on which months you're counting!
