How to Calculate the Date 30 Days Ago
You can figure out the date thirty 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 30 total days.
Instead of counting down, you can move backward one day at a time while subtracting 1 from 30 for each day you move back. You can also move backward one week at a time while subtracting seven from 30 for each week you move backward.
Continue this process until your original number has reached zero. This is the date 30 days ago.
You can also use this method to find the date 30 days from today.
Starting date: August 22, 2026 (Saturday)
Days to subtract: 30
Result: August 22 − 30 days = July 23, 2026 (Thursday)
