Hello,
I need a formula in Data Validation that restricts the entry of a date to a/any Monday.

The entry in the screenshot below allows no "mm/dd" entry whatsoever... shown only to help explain what is desired.  Thanks in advance...

Change the "Allow" choice to "Formula" and enter this:
=WEEKDAY(A1)=2

Where A1 should be the first cell in your range for data validation.
