i would think that on non-leap years you would 'age' on the 1st of March. but i can see where the confusion lies. for days before Feb 29th you get to the next year by adding 365 days on years except the leap year. so for 2000-2004. [366, 365, 365, 365] for days after Feb 29th you get to the next year by adding 365 days on years except the year before the leap year. so for 2004-2004. [365, 365, 365, 366] if you use one of these rules for Feb 29th you get the next year falling on Feb 28th or Mar 1st for non-leap years..
