You can easily find the date 17 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 17 weeks.

Instead of counting up, you can move backward one week at a time while subtracting 1 from 17 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 17 weeks ago.
