There are WAAAAY too many wacky edge cases that can bite you in the butt. http://www.php.net/manual/en/function.date-create.php Use a DateTime object. You can do all sorts of manipulations to it and it will handle all the timezone, daylight savings, leap year, and similar weirdness for you. It also supports 64-bit dates internally so you can cover the entire span of human history and then some. -- Larry Garfield AIM: LOLG42 larry@garfieldtech.com ICQ: 6817012 "If nature has made any one thing less susceptible than all others of exclusive property, it is the action of the thinking power called an idea, which an individual may exclusively possess as long as he keeps it to himself; but the moment it is divulged, it forces itself into the possession of every one, and the receiver cannot dispossess himself of it." -- Thomas Jefferson
