Hi,I am creating an elearning system for which the current date is to be displayed in the format DD/MM/YYYY. I also need to include a date 14 days previous to the current date in the same format.Displaying the current date in that format isnt a problem. I can change the date using the code:-<script type="text/javascript">var d = new Date()d.setDate (-14)document.write(d)</script>but this displays the date as 'Tue Apr 11 15:25:22 UTC+0100 2006' .Ive tried this code..<script type="text/javascript">var d=new Date()var day=d.getDate() - 14var month=d.getMonth() + 1var year=d.getFullYear()document.write(year + "/" + month + "/" + day)</script>..but this just deletes 14 off the current day number (which is no ruddy use!!)Please can someone help out...? :) ThanksMuncan

You need first set new Date to date/time needed and then split that setted date to DD/MM/YYYY:

var myDate = new Date();myDate.setDate(myDate.getDate() - 14);document.write(myDate.getDate() + '/' + myDate.getMonth() + '/' + myDate.getFullYear());

argh! sorry!

var myDate = new Date();myDate.setMonth(myDate.getMonth() + 1);myDate.setDate(myDate.getDate() - 14);alert(myDate.getDate() + '/' + myDate.getMonth() + '/' + myDate.getFullYear());

should work OK now? :)edit:-24 -> -14 :)

LOL! sorry, that was second mistake for I, testing it and forget change date back to -14.But now it's OK. Reason of that +1 is: JS year start from zero. January is month 0.
