Excel Formula: Check If Date is Last N Day of Today

Supposing you have a table in Excel, column B is the product name, column C is the corresponding production date, and the shelf life of the products is 7 days. Now to check if the products are due today, you can use a formula to check if the production dates are last 7 days of today.

Generic formula

AND(date>=(TODAY()-n),date<TODAY())

Syntaxt and arguments

 Date: a cell that refers to a date or a date enclosed with double quotation marks that you want to check if it is last n day of today. N: the number of day that you use to check.

Return value

If the date is last n day of today, it returns TRUE;
If the date is not last n day of today, it returns FALSE.

How this formula works

To check if the dates in range C3:C9 are last 7 days of today, please use below formula:

=AND(C3>=(TODAY()-7),C3<TODAY())

Or directly use a date enclosed with double quotation marks

=AND("11/10/2021">=(TODAY()-7),"11/10/2021"<TODAY())

Press Enter key to get the first result, then drag autofill handle down to show all dates’ results.

Explanation

TODAY function: returns to the date of today.

AND function: tests multiple conditions and returns TRUE or FALSE.

Here the formula is divided into two parts:

date>=(TODAY()-7) checks if the date is last 7 days of today;

date<TODAY() checks if the date is later than today.

While both parts return TRUE, the whole formula returns TRUE, or it returns FALSE.
