This requires VBA code or a formula that uses iterative calculation (circular references).

If you want to try the latter, do the following first.

  • Select File > Options.
  • Select Formulas.
  • Tick the check box 'Enable iterative calculation'.
  • Click OK.

Let's say you want to enter data in A2 and down.

Enter the following formula in B2:


Format B2 as a date.

The formula can be filled down if desired.
