Year = starts at 1 (not literally, but for all intents and purposes). Day = starts at 1. Month = starts at 0? What?! :) >> >> >> // Todd > It makes no sense does it?!

In that sense, I can see the reasoning of why months and days of the week work that way (even though I think it's counter-intuitive and subtraction is a pretty simple operation). I don't understand why the day of the month or of the year would be zero-based, though. It's almost like the function just takes the number of seconds elapsed since the beginning of the year, divides by 86400 and truncates the result to a integer.
