12 weeks ago

The date 12 weeks ago from today is Thursday, December 18, 2025

This calculation is made using today's date (Thursday, March 12, 2026)

You can easily find the date 12 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 12 weeks.

Instead of counting up, you can move backward one week at a time while subtracting 1 from 12 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 12 weeks ago.

You can also use this method to find the date 12 weeks from now.
