How to Calculate the Date 21 Days Ago

You can figure out the date twenty-one days ago manually by using a calendar. Look at today's date on the calendar and count backward one day at a time until you've counted 21 total days.

Instead of counting up, you can move backward one day at a time while subtracting 1 from 21 for each day you move backward. You can also move backward one week at a time while subtracting seven from 21 for each week you move backward.

Continue this process of subtracting the days until your original number has reached zero. This is the date 21 days ago.
