so plz help me in providing me the relevant code.

thanks in advance.

Date formats always seemed finicky to me, I usually have to test several versions before I get one to work. The first thing I would suggest is figuring out what formats your system recognizes as a valid date. Everything that comes through a form is passed to the script as a string, so if it isn't immediately recognizable it will likely fail. So to test, try a series of dates as strings in different formats, and try to get the script to convert to other date formats or use them in date calculations (such as dateDiff() ).
