How many seconds until Christmas?
This is the fastest countdown on the site. The number above shows how many seconds until Christmas and it changes every single second. It counts down to 00:00:00 on Friday 25 December 2026 in your own time zone.
Every day holds 86,400 seconds, so the number drops by that much each day. It starts the year in the tens of millions and reaches six figures only in the last day or so.
Second maths
- 1 minute = 60 seconds
- 1 hour = 3,600 seconds
- 1 day = 86,400 seconds
- 1 week = 604,800 seconds
- Christmas Eve alone = 86,400 seconds of waiting
- 1 million seconds = about 11.6 days, so the count passes one million in mid-December
How accurate is the seconds countdown?
The countdown is as accurate as your device's clock. Phones, tablets and computers set their time automatically over the internet, usually to within a fraction of a second, so the countdown here should match the moment midnight arrives on your own clock.
If the seconds seem to stall when you come back to the tab, that is your browser saving power on hidden tabs. It catches up the moment you look again, because the countdown always recalculates from the real time rather than counting ticks.
The final countdown
Keep this page open on Christmas Eve and switch on the music at the top. In the last 10 seconds, count down out loud together. At zero, the page switches to a Merry Christmas message.

Seconds and Christmas Eve traditions
Counting down the last seconds is better known at New Year, but it is becoming a Christmas Eve habit too, especially with older children who stay up for midnight. Some families open one present when the seconds reach zero; others ring a bell, a nod to the bell in The Polar Express. Whatever you do, it is a nice way to mark the exact start of Christmas Day together.
