Countdown Timer
A live countdown to any date and time — days, hours, minutes and seconds.
The Countdown Timer tracks the time until any moment you choose — a birthday, New Year, a product launch, a holiday, exam day or a project deadline — with a big, live ticking display of days, hours, minutes and seconds. Set the target date and time (and an optional event name) and the countdown updates in real time, right in your browser.
Unlike a static 'days remaining' figure, a ticking countdown builds anticipation and makes waiting concrete. The display counts down to the second, and once the moment passes it gracefully tells you the event has arrived. It is also handy for practical time-boxing: count down to the close of a sale, the end of a shipping window or the start of a live stream.
The timer runs entirely client-side, so the countdown is based on your device's clock and works offline. It does not persist between page loads — keep the tab open while you count.
Pick a target date and time to start the live countdown. The timer updates in real time and works entirely in your browser.
How to use the Countdown Timer
- Pick the target date and time using the date-time picker (uses your local time).
- Optionally give the event a name, like 'New Year 2027'.
- Watch the live countdown tick down in days, hours, minutes and seconds.
- Keep the tab open — the timer updates every second.
- After the target passes, the tool marks the event as reached.
Frequently asked questions
What timezone does the countdown use?
Your local time. The date-time picker and the countdown both use the timezone your device is set to, so the target is interpreted exactly as you enter it — no UTC conversions to puzzle over.
Does the timer keep running if I switch tabs?
Yes — it keeps tracking elapsed time based on the clock, so when you return the display is still correct. Browsers may throttle background tab timers, but the countdown re-syncs from the current time each tick, keeping it accurate.
Can I count down to something years away?
Yes. The days figure simply grows into the hundreds or thousands and the timer keeps ticking. For long horizons many people prefer the simpler 'days until' number, but the full countdown works at any scale.
Is a countdown timer different from a stopwatch?
Yes. A stopwatch counts up from zero to measure elapsed time. This countdown counts down from now to a fixed future moment. For measuring how long a task takes, use a stopwatch; for time remaining until an event, this is the tool.
