How many hours are there in each month?

On average, any given month has 730.48 hours.

You can calculate that yourself, by using 24 h/day * [number of days in month] - for example, for January: 24h * 31 days = 744h

For calculating the average number of days for February, we have to consider that every 100 years has 24 leap years and 74 non-leap years. Given that, we can calculate the average number of hours using (672*76+696*24)/100=677.76

The total average is computed by summing all the months’ number of hours and dividing by 12:

(744+677.76+744+720+744+720+744+744+720+744+720+744)/12=730.48
