Set a countdown timer for any length of time. Audio alarm when done. Run multiple timers simultaneously.
How to use the Countdown Timer
Set your time and start
Set the hours, minutes and seconds, add an optional label for the timer, then click Start. The countdown begins immediately with a large visual display. Click Pause to freeze it and Resume to continue from where it left off. Reset brings it back to the time you entered.
Audio alarm
When the timer reaches zero, an alarm sound plays and the display flashes red. Click anywhere on the done display to dismiss it. Make sure your browser tab is not muted if you need the alarm — some mobile browsers require a user interaction first before audio can play.
Run multiple timers
Click Add timer to create a second countdown running independently of the first. Each timer has its own label, time setting and controls. This is useful for cooking multiple dishes, running classroom activities with different time limits, or tracking halves in a football match.
