>Tell me if there is any function in Javascript to check whether a date is valid or not.
Try the parse method of the Date object, if you pass it a string, it returns either the milliseconds since midnight 1/1/1970 if it is valid date or else NaN (check with isNaN()).
function CheckDate( DateString )
{
return( ! isNaN( Date.parse( DateString ) ) ) ;
}
