Date Difference in Java Script

Question

Hi,
I need a validations for two dates.
"From Date" should be less than "To Date"
I am sure that I am getting two dates in valid format only as I am picking then from a Calendar Object.
I need to check only one condition that From Date should be less than To Date.
I am getting the Date values as String as these are from a text field in the HTML.
The date format(pattern) is not fixed as it depends on the Locale Settings.
The date should support all the patterns available.
I am not able to parse the dates to a valid value.
I am facing problems with some formats(MM.dd.yyyy) while parsing to a date value.
new Date(07.01.2004) --> giving NaN.
Kindly suggest me,
Thanks

I think you should use java.text.SimpleDateFormat, for example:
DateFormat df = new SimpleDateFormat("MM.dd.yyyy");
try {
    Date risult = df.parse("07.01.2004");
} catch (ParseException e) {
    // do something with exception
}To compare the dates try "before" and "after" methods of class Date.
