I'd consider using Calendar objects instead of Date objects too. If you have a look at the methods avaliable to a Calendar object you'll see why. [ September 20, 2004: Message edited by: Paul Sturrock ]
Thanks for the solutions. It worked. I was not aware of calendar class. This relaly helped in learnign date related manipulations using java. Hope that u will help me in future also. Thanks once again.
