Count back from today
How the days are counted
We count the days after the date, up to and including today, so yesterday was 1 day ago. Without a year, a date means its most recent occurrence: today, Tuesday, September 29, 2026, "December 25" means Thursday, December 25, 2025.
Pick a date with a year in the form above to count from any day back to the year 1000.

Frequently asked questions
How are the days since a date counted?
From the date up to today: the date itself isn't counted and today is, so yesterday was 1 day ago and the same weekday last week was 7 days ago.
What if the date hasn't come round yet this year?
Then the most recent one was last year, and that's the one we count from. To count from a particular year, enter the full date in the form.
What happens if I pick a future date?
You'll get a countdown instead (the days left until that date), because it hasn't happened yet.
How is February 29 handled?
It counts from the most recent leap day, because February 29 only exists in leap years.
