[...] snipped I ignored the rest as it was beyond me. I'm also a newbie to PHP but I looked into dates in Perl. I quickly began using a module from CPAN as I realized this was more complicated than meets the eye and you seem to indcate that when you mention leap years. I would question why you accept input as a particular format. It's certainly easier to work with timestamps than arbitrary representations of dates. I would not be so quick to assume you have to accept input as is. Or at least have it fixed to a format ... but the Perl modules I've worked with are liberal with what they receive .... :) Anyhow, I'd just find a PHP module ot handle this. I found this: http://www.phpbuilder.com/columns/akent20000610.php3 but I'd just want a class (guess you call it that in PHP). And then this looks real interesting: > Date/Time Processing with PHP > By The Disenchanted Developer > March 19, 2002 http://zope1.devshed.com/zope.devshed.com/Server_Side/PHP/DateTime/page1.html In Perl I happen to use this moduel for date manipulation: http://search.cpan.org/doc/STBEY/Date-Calc-5.0/Calc.pod There must be something similar in PHP but since I too am a newbie (and lazy to boot) I don't know what it is.
