Days Until Calculator
Find out how many days are left until any date, or how many days ago it was if it's already passed.
How this is calculated
The countdown counts from today up to and including your target date, so a date tomorrow shows 1 day, not 0. A date that's already passed shows how many days ago it was instead.
Frequently asked questions

What if the date I enter has already passed?
The calculator shows how many days ago it was instead of a countdown. It works for any date, past or future.
