Days Until — Countdown
Count down to a birthday, holiday, deadline or any future date — in days, with a live timer showing the exact time left.
How the countdown works
The headline number counts whole calendar days from today to the target date. If today is 14 November and the target is 25 December, the answer is 41 days — the same way you would count days off on a wall calendar.
The live timer below it counts the exact time remaining to midnight at the start of the target date in your own time zone, ticking every second. Because the timer measures exact 24-hour periods and the headline counts calendar days, the two numbers can differ by one on the final day. The headline day count is the one to use when you talk about "days to go".
If the date you pick has already passed, the calculator tells you so instead of showing a countdown.
Worked example
From 14 November 2026, there are 41 days until Christmas Day on 25 December 2026. November has 30 days, so 16 days remain in November after the 14th (30 − 14 = 16), plus 25 days in December: 16 + 25 = 41. Christmas Day 2026 falls on a Friday.
Frequently asked questions
What time does the countdown end?
At midnight at the start of the target date, in your own time zone. When the day itself arrives, the countdown shows that the date is today.
Can I count down to a date in the past?
No — the calculator will tell you the date has already passed. To measure a gap between two past dates, use the Days Between Dates calculator instead.
Why does the exact timer show a different number of days?
The headline counts whole calendar days; the timer counts exact 24-hour periods. Partway through the day before the target date, the timer may show 0 days while the calendar count still says 1 day to go. Both are correct — they just measure different things.
How do the preset buttons work?
Each preset picks the next occurrence of that day. If this year’s Christmas has already passed, the button counts down to next year’s Christmas instead.
Does the countdown keep running if I leave the page?
No. The countdown runs in your browser, so closing the page stops it. When you come back, just pick the date again — the day count will be correct, because it is always worked out from today’s date.
