Countdown Timer
Set a target date and time and watch a live countdown tick down to zero.
Set a date and time to start the countdown.
The countdown reads your device’s clock each second, so it stays accurate even after the tab has been in the background. When the target time arrives it stops at zero. Everything runs in your browser.
How to set a countdown
Choose the date and time you're counting down to. The days, hours, minutes and seconds appear at once and tick down every second on their own until the target is reached.
When a live countdown helps
Building anticipation for a launch or sale, timing a presentation, counting down to New Year, or keeping an eye on a deadline. Leave the tab open and it keeps running.
Questions
Does the countdown keep running if I switch tabs?
The timer reads your device's clock on every tick, so even if a background tab is throttled the moment you return it snaps to the correct remaining time rather than drifting.
What happens when the countdown reaches zero?
When the target time arrives the timer stops at zero and shows that time is up, instead of rolling into negative numbers, so it reads cleanly on screen.
Can I count down to a specific time, not just a day?
Yes. You set a full date and time as the target, so the countdown is accurate to the second — useful for launches, deadlines and live events.
