How to Calculate the Date 40 Days Ago

You can figure out the date forty 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 40 total days.

Instead of counting up, you can move backward one day at a time while subtracting 1 from 40 for each day you move backward. You can also move backward one week at a time while subtracting seven from 40 for each week you move backward.

Continue this process of subtracting the days until your original number has reached zero. This is the date 40 days ago.
