How many days until…?
Choose a target date and the countdown appears instantly: D-10 means ten days to go, D+8 means eight days have passed, and D-day means it's today. The “From” date defaults to today, but you can change it to count between any two dates.
- Weeks + days — the gap split into whole weeks and leftover days.
- Months (approx.) — days divided by the average month length (30.44 days).
- Weekdays / weekend days — Monday–Friday versus Saturday–Sunday between the two dates (public holidays aren't excluded).
Save your countdowns
Give a countdown a name and save it — exams, trips, birthdays, deadlines. The list is stored only in this browser and updates every day you visit.
Frequently asked questions
Is the target day itself included?
The count is the plain difference between dates, so tomorrow is D-1. Tick “Count the start date as day 1” for anniversary-style counting.
