Days Until Calculator
Calculate how many days are left until a date (or how many have passed, if it's already behind you), with a breakdown into full weeks and leftover days.
How is it calculated?
Days = target date − today, in full days. A positive result means the date is in the future; negative means it already passed; zero means it's today.
Examples
Days until a future date
79 days (11 weeks and 2 days) — it's a future date.
Days since a past date
279 days (39 weeks and 6 days) have passed since that date.
Use cases
A few common examples:
- Countdown to an event, trip, or deadline.
- Find out how much time has passed since a milestone (a start date, an anniversary...).
- Plan ahead by knowing how many weeks you have left to get organized.
