Welcome to the forum.

If you step back a little and look at your first post from a slightly different angle, you will agree that you have not given us TOO much to work with. On top of the usual ones like "What's your OS? shell?" , quite some questions are left open, as
- is THAT the parameter file structure: $variable= value? Sure about the $ sign?
- WHAT is the date format - ddmmyyyy or mmddyyyy? (i.e. WHAT should we increment?)
- is that a task for a script or better done manually?
- how often should it run? year in and year out?
- would it need month and year increment as well, then, and leap years considered?
