I like Date::Calc, personally. I wound up writing a wrapper object for it that would split dates into separate $yy, $mm, $dd variables, call into Date::Calc, then reassemble the results into what I wanted.

Whichever solution you go with, I'd suggest writing wrappers around the subset you need if you only need a few functions out of 50, make the API what you want it to be, and use that. --wesley
