Countdown Timer
100% PrivateProductivity ToolsCount down from a duration you set, or to a specific clock time.
Runs entirely in your browser. Your input is not uploaded to Ovatly or anywhere else.
The countdown is calculated from the real clock, so it stays correct if the tab is throttled in the background. The finishing beep plays when the browser next wakes the tab, which can be late if the device itself is asleep.
- 1Choose Duration or Target date and time.
- 2For a duration, enter hours, minutes and seconds. For a target, pick the date and time.
- 3Press Start countdown and watch the remaining time; Pause holds it and Resume continues.
- 4When the countdown reaches zero the timer beeps and shows Time is up; press Reset to set a new one.
Choose Duration, enter 1 hour and 30 minutes, and press Start. The timer shows 1:30:00 and starts counting down, and the line under it shows the clock time it will end. Halfway through it reads 45:00 remaining, and at zero it beeps and displays Time is up.
- Remaining time is calculated from the real clock on every update, so background tab throttling cannot make it drift.
- The finishing beep plays when the browser next wakes the tab; if the whole device is asleep, the sound can be late even though the countdown itself ends on time.
- Durations are whole hours, minutes and seconds up to any number of hours; target times must be in the future.
Yes. Use Target date and time mode and the display switches to a days format, for example 3d 04:12:45 remaining.
About this tool
The Countdown Timer counts down to zero in two ways: for a duration you set in hours, minutes and seconds, or to a specific date and time, such as a launch, a deadline or the end of an exam. It shows the remaining time in large type, the exact moment it will end, and sounds a beep when it finishes.
