How to Calculate the Date 12 Months Ago

You can easily find the date twelve 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 12 total months.

Instead of counting up, you can move backward one month at a time while subtracting 1 from 12 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 12 months ago.

You can also use this process to find the date in 12 months.
