How do I set a countdown timer to a specific date?
Enter an optional name, pick the target date and time in the date picker, and click "Add Timer". The countdown starts right away and shows the time left as days, hours, minutes and seconds (for example 12d 4h 37m 9s), updating once per second. The card also shows the exact target date and time in your local format, so you can check you picked the right day.
The target must be in the future. If you pick a time that has already passed, the tool asks you to choose a future date instead of creating a timer that is already finished. If you leave the name empty, the card is labeled "Countdown".
How do I make a countdown for a set number of minutes?
Add the minutes to the current clock time and use that as the target. This tool counts down to a moment on the calendar rather than from a duration, so a 25 minute focus session started at 2:10 PM is a timer set to 2:35 PM today. The same approach works for any length:
- Pomodoro (25 minutes): it is 9:05 AM, set the target to 9:30 AM.
- Workout interval block (45 minutes): it is 6:20 PM, set the target to 7:05 PM.
- Exam or study block (2 hours): it is 1:00 PM, set the target to 3:00 PM.
- Overnight (8 hours): it is 11:30 PM, set the target to 7:30 AM on the next day's date.
Remember to change the date when the end time falls after midnight, otherwise the target lands in the past and the timer will not be created.
What can I count down to?
Anything with a fixed date and time. Because the timer counts days as well as hours, it works just as well for an event months away as for a deadline this afternoon. Some common setups:
| Use case | Example name | Target to enter |
|---|---|---|
| New Year | New Year 2027 | January 1, 2027, 12:00 AM |
| Project or assignment deadline | Final report due | The due date at the submission cutoff time |
| Wedding, birthday or party | Our wedding | The ceremony or start time |
| Trip or flight | Flight to Lisbon | Departure time (or the time you need to leave home) |
| Product launch or sale end | Launch day | The go-live time in your time zone |
| Study or focus session | Chapter 4 review | Current time plus the session length |
Can I run more than one countdown at the same time?
Yes, you can run up to 10 countdowns at once. Each timer gets its own card with its own name, live countdown and target date, and they all tick independently. This makes it easy to track several dates side by side, such as a work deadline, a holiday and a birthday. When you reach 10, the tool shows a message asking you to delete one before adding another. Finished timers stay on the list and count toward the 10 until you delete them. Each card has a "Delete" button in its corner.
What happens if I close the tab or reload the page?
Your timers are saved automatically in your browser's local storage, so they come back when you reopen the page in the same browser. The countdown is always calculated from the target date, not from a running clock, so no time is lost while the page is closed: if you close the tab with 3 days left and return 24 hours later, it shows about 2 days left.
A few details are worth knowing:
- Timers stay on one device. Saved timers live in that browser only. They do not sync to your phone, another browser or another computer.
- Private windows forget. In a private or incognito window, browsers usually clear local storage when the window closes, so your timers go with it.
- Clearing site data removes timers. Clearing cookies and site data for this site deletes the saved list.
- Timers that end while the page is closed are kept. If a target passes while the page is closed, the timer is not removed. The next time you open the page its card shows "Ended on" followed by the target date and time, so you can see what you missed, and it stays there until you delete it. No beep or notification plays for these, because the moment has already passed.
What happens when a countdown reaches zero?
Three things happen when a countdown ends while the page is open:
- The card shows "Time's up!" in a highlight color. The finished timer stays on the list until you delete it, so you will still see it if you were away from your screen. After a reload, the same card shows "Ended on" with the target date and time.
- A short beep plays. The tool makes a tone of about one second with your browser's built in audio, no sound file needed. Browsers only allow a page to play sound after you have interacted with it, so the beep is unlocked when you click "Add Timer" or anywhere on the page. If you reopen the page and a saved timer ends before you click anything, it may finish silently. Check that your device is not muted.
- A browser notification appears, if you turned it on. Click "Notify me when a timer ends" and allow notifications when your browser asks. The tool never asks on its own when the page loads. After that, you get a notification with the timer's name each time one ends, even if you are looking at another tab or app. If you block notifications, or your browser does not support them, the beep and the on-page message still work.
The page has to stay open, in a tab or a background window, for the beep and notification to happen. Nothing can alert you once the tab is closed.
Is this a countdown timer generator I can embed or share?
No. This is a personal countdown maker that runs in your own browser. It does not create share links, embed codes or images for a website. It suits planning and personal tracking rather than publishing a countdown on another page.
How accurate is the countdown?
The countdown is as accurate as your device clock. It compares the target with your computer or phone's current time once per second, so if your clock is set automatically from the internet, the result is accurate to the second. The target you enter is read in your device's local time zone, which matters when you count down to an event in another city: convert the event time to your own time zone before you enter it.
When the tab is in the background, browsers may slow down how often pages update to save power, so the beep and notification can occasionally arrive a little after the exact second. The countdown itself never drifts, because it is recalculated from the target each time.
