How to Calculate the Date 21 Weeks Ago

You can easily find the date twenty-one weeks ago by looking at a calendar. First, find the starting date on the calendar, then count backward one week at a time until you've counted 21 total weeks.

Instead of counting up, you can move backward one week at a time while subtracting 1 from 21 for each week you move backward. Continue this process of subtracting the weeks until your original number of weeks has reached zero after subtracting. The result is the date 21 weeks ago.

You can use this same method to find the date in 21 weeks.
