I would like to set up a spreadsheet, in order to monitor when someone is due
a repeat order.The orders are due every 84 days I would be grateful for any
advice.
I will be using excel 2003.

Days are stored as serial numbers, with 1 = 1 Jan 1900 (or 2 Jan 1904 depending
on date system being used)

So to change the date by 84 days, merely add or subtract 84 from your date:

e.g. Date in A1

=A1+84

Format as date.
