Countdown Timer

What does the Countdown Timer do?

Use quick presets (1, 3, 5, 10, 15, 25, 30 or 60 minutes) or enter hours, minutes and seconds — or switch to “Until a date & time” to count down to an exam, launch or event. The remaining time also shows in the browser tab title, so you can work in another tab.

When the timer ends it plays a short beep, can show a system notification (if you allow it) and vibrates on supported phones. Because time is calculated from the end timestamp, the countdown stays accurate even if the tab sleeps.

Examples
