Countdown Timer
Count down to any date and time. Pick your target and watch a live tally of the days, hours, minutes and seconds remaining, updating every second.
Pick a target date and time to start the countdown.
How it works
A countdown shows how much time is left until a moment you care about — a holiday, a launch, a deadline or a birthday. Choose the target date and time and the tool works out the difference from your device's current clock, then updates it once a second so the seconds tick down live.
If the target has already passed, the display flips to show how long ago it was instead. Everything runs locally against your own clock, so the countdown is as accurate as your device's time.
Examples
- Count down to New Year, a birthday or a product launch.
- Once the date passes it shows how long ago it was.
- The seconds update live, every second.
Frequently asked questions
- How accurate is the countdown?
- It counts against your device's clock and updates every second, so it is as accurate as your device's time setting.
- What happens after the date passes?
- The label switches from “time remaining” to “time since” and counts up, showing how long ago the moment was.
- Does it keep running if I switch tabs?
- It recalculates from the real clock each second, so when you return the numbers are correct even if the tab was backgrounded.
- Is my target date saved anywhere?
- No — the countdown runs entirely in your browser and nothing is sent to a server.
