## Excel Formula: Check If Date Is Last N Month from Today

Supposing you need to check if staff’s entry date is last 6 months from today, you can use a formula combined by AND, EOMONTH and TODAY functions in Excel to quickly handle the job.

Generic formula

AND(date>EOMONTH(TODAY(),-(n+1)),date<=EOMONTH(TODAY(),-1))

Syntaxt and arguments

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

Return value

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

How this formula works

To check if the dates in range C3:C9 are last 6 months from today, you can use the formula like this:

=AND(C3>EOMONTH(TODAY(),-(6+1)),C3<=EOMONTH(TODAY(),-1))

Or directly use a date enclosed with double quotation marks

=AND("12/4/2020">EOMONTH(TODAY(),-(6+1)),"12/4/2020"<=EOMONTH(TODAY(),-1))

Press Enter key to get the first result, then drag auto fill handle down to get other results.

Explanation

TODAY function: returns to the date of today.

EOMONTH function: gets the last day of month n months in future or past.

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

Here the formula is divided into two parts:

date>EOMONTH(TODAY(),-(6+1)) checks if the date is last 6 months from today;

date<=EOMONTH(TODAY(),-1) checks if the month of the date is equal to or later than today.

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