Excel formula: Date is same month and year

Generic formula

=MONTH(date1)&YEAR(date2)=MONTH(date1)&YEAR(date2)

Summary

If you need to test two dates to see they both have the same month and year, you can do so with a simple formula that uses the MONTH and YEAR functions.

Explanation

In the example, the formula in cell D6 contains this formula:

=MONTH(B6)&YEAR(B6)=MONTH(C6)&YEAR(C6)

In this case, Excel extracts the month from the date in cell B6 as numbers, then concatenates them together to form a text string. The same thing is done with the date in cell C6, the month and year are extracted and joined together.

Finally, the formula then tests for equivalency using the equal sign. Both dates are in January 2000, so the formula is solved as follows and returns TRUE.

=MONTH(B6)&YEAR(B6)=MONTH(C6)&YEAR(C6)
=1&2000=1&2000
="1200"="1200"
=TRUE

If you need to test a date to see if has the same month and year as the current date (today), you can use this formula:

=MONTH(date)&YEAR(date)=MONTH(TODAY())&YEAR(TODAY())
