The idea is brilliant, however it does not seem to do correct for the years dividable by 400, if I recall correctly 1600 an 2000 should be different from 1596 and 2004? Or no? Is that a bug in FileMaker? http://en.wikipedia.org/wiki/Leapyear

Sorry last post, it all seems OK, 1700, 1800, and 1900 is not the same as 2000, that’s what I had in mind.
