How many days until your anniversary?
Enter the date you're marking — a wedding, a first date, a work milestone — and the countdown targets its next anniversary, with the days remaining, the weeks and days, and the weekday.
Enter the original date to see exactly how many days until its next anniversary.
Pick the date to see the countdown to its next anniversary.
The countdown is measured from today to the next occurrence of that month and day, in whole days.
How does it work?
Days are counted in whole calendar days using UTC, so the result is unaffected by time zones or daylight saving. A negative count means the date has already passed.
Days-until formula
- d
- Whole days between today and the target date.
- target
- The date you are counting down to.
- today
- The current date (your local today).
From 1 June to 1 July is 30 days.
Method & sources
We count whole calendar days from today to the date you choose. Both dates are handled in UTC so time zones and daylight saving never shift the result. You pick the target date yourself — the calculator does not look up holidays or official calendars.
How we calculate
- The count is whole days from today to the date you choose.
- Today is your device's local date; the target date is the one you pick.
- A negative count means the date has already passed.
- The day of the week shown is the weekday the target date falls on.
Rounding
The countdown is in whole calendar days. Today and the target date are counted in UTC, so time zones and daylight saving never shift the result.
What this countdown does

How the days are counted
The count is in whole calendar days from today to the date you pick, calculated in UTC so it never drifts with time zones or daylight saving. If the date has already passed, the count shows how many days ago it was.
