For validating that, just have an array of the months ("JAN", "FEB", "MAR", etc.) and check that the first three characters (using substring()) are one of the months. Then check that the last two are digits.

To add months, just use setMonth with the current month (getMonth()) + how many months you want to add.

You need to use the Date() object. The dates need to be set in a Date object and then comparing is easy. To set the month, use an array of months and loop over until the correct month is found and that would be the number to pass to setMonth(). Use setFullYear() for the year with "20" appended. You could use setFullYear() for both - see this link.
