How to Calculate the Date 15 Months Ago

You can easily find the date fifteen months ago by looking at a calendar. First, find the starting date on the calendar, then count backward one month at a time until you've counted 15 total months.

Instead of counting up, you can move backward one month at a time while subtracting 1 from 15 for each month you move backward. Continue this process until your original number of months has reached zero after subtracting. The result is the date 15 months ago.

You can also use this process to find the date in 15 months.
