Countdown Timer
Count down to any date and time — days, hours, minutes and seconds, ticking live in your browser.
Nothing you type is saved or sent anywhere — everything stays in your browser.
How to use this countdown timer
This countdown timer counts down to any date and time you choose — a birthday, a holiday, an exam, a launch. The numbers tick once every second, in your browser, and nothing you type is saved or sent anywhere.
Step 1: Pick the date you are counting down to. Use the date picker to choose the day.
Step 2: Pick the time if you want one. The time defaults to 00:00, midnight at the start of the day. Add a name for the event if you like — it will show above the countdown.
Step 3: Watch the countdown. Days, hours, minutes and seconds tick down once a second until the moment arrives, when the timer shows “Time is up!” and stops at zero.
Worked example
Say you want to count down to New Year. Pick 1 January 2027 as the date, leave the time at 00:00, and type “New Year” as the event name.
From 22 December 2026 at 00:00 to 1 January 2027 at 00:00 is exactly 10 days. So if you open the countdown timer on 22 December, it will show 10 days, 0 hours, 0 minutes and 0 seconds — then it will start ticking down, second by second.
Add a time to sharpen it. Counting down to 1 January 2027 at 09:00 instead of midnight adds 9 hours to the wait, and the countdown timer will show 10 days and 9 hours on 22 December. The maths is simple: the timer works out the time left from your device’s clock, then splits it into days, hours, minutes and seconds.
What the countdown counts
The display shows full days first, then the hours, minutes and seconds left over. A countdown of 2 days and 3 hours means two whole days plus three hours, not two days measured in hours. The seconds box is the one that moves the fastest, ticking down once every second.
The countdown timer uses your device’s own clock, so it stays in step with your time zone. If your clock is right, the countdown is right. It does not need the internet, and it does not talk to any server — everything happens in your browser. Close the page and the countdown stops; open it again with the same date set and it starts again.
When the moment arrives, the numbers stop at zero — 0 days, 0 hours, 0 minutes, 0 seconds — and the countdown timer shows “Time is up!”. Nothing goes negative, and the page does not keep counting past the event.
Good uses for a countdown
Birthdays and holidays are the classic countdowns. Watching the days fall away makes the wait part of the fun, and it is handy for planning too — you can see at a glance whether there are 10 days or 100 days left.
Exams and deadlines work the same way. A countdown to an exam date keeps the remaining time in front of you, which is often more motivating than a date written in a diary. The same goes for launches, trips and weddings — anything with a date you are waiting for.
Some people use a countdown for a habit or a challenge: days until a holiday, days left of a course, or the time until a new job starts. Whatever the event, the rule is the same — pick the date, pick the time if it matters, and let the countdown do the watching.
A countdown can also stop you missing a date. Booking windows, ticket sales and early-bird prices all open and close on a day, and a timer ticking down to that day is a simple reminder that the moment is coming.
Frequently asked questions
What is a countdown timer?
A countdown timer shows how much time is left until a date you choose. It counts down in days, hours, minutes and seconds, and it ticks once every second.
Does the countdown keep running if I close the page?
No — it runs in your browser, so keep the page open. Reopening it with the same date set starts the count again.
What time zone does it use?
It uses your device’s own clock and time zone. The countdown is worked out from the time on the device you are looking at the page on, so it always matches your local time.
What happens when the countdown reaches zero?
It shows “Time is up!” and stops at zero — 0 days, 0 hours, 0 minutes and 0 seconds.
Can I count down to a time as well as a date?
Yes — pick a time as well as a date. If you leave the time at 00:00, the countdown runs to midnight at the start of your date.
