For some reason I couldn't wrap my mind around how the leap years should be tested. After using three sheets of paper to write out how the logic would make sense, and using Wikipedia, I think I've come up with something that makes more sense in my mind. I hope it helps someone else:
In simple terms:
Where the program should terminate kept hanging me up.
Good help from Wikipedia:
...most years whose division by 4 equals an integer are leap years. Years that are evenly divisible by 100 are not leap years, unless they are also evenly divisible by 400, in which case they are leap years.

I think I would change it just a little bit ... If the year is divisible by 400, than it's true -- final answer If the year is divisible by 4 but (and) is not divisible by 100, than it's true -- final answer Otherwise it's false -- final answer
