Yearhours

There are 8760 hours in a year, which is quite a cool descending number. But wait: that's a regular 365-day year. What about the extra quarter day that adds the leap-year's 29th Feb every four years? But it's not quite a a whole quarter day. Could it be that the average length of a year in hours is 8765 hours, 43 minutes and 21 seconds?

Could it? Could it?
