How many hours are there in a year?

There are 8,760 hours in a year. This is based on the fact that there are 24 hours in a day and 365 days in a year. So, if you multiply 24 by 365, you get 8,760. However, in a leap year (which occurs every four years), there are 8,784 hours since there is an extra day (February 29th).
