You can easily find the date 4 weeks ago on a calendar. First, find the starting date on the calendar, then retreat the calendar one week at a time until you've counted 4 weeks.

Instead of counting up, you can move backward one week at a time while subtracting 1 from 4 for each week you move backward. Continue this process of subtracting the weeks until your original number of weeks has reached zero. The result is the date 4 weeks ago.
