I can't seem to follow the code because I'm just new with javascript and programming, got this code from here: http://www.planet-source-code.com/vb/scripts/ShowCode.asp?txtCodeId=2608&lngWId=2

Answer 1

The calculations in this code are just plain wrong. I suggest you don't bother fixing it. Instead, use a reliable calendar that is widely used like the jQuery UI datepicker
