Online Timer
Set a length of time, press Start, and the alarm rings when it reaches zero.
How it works
Type a number of hours, minutes and seconds — or tap a preset — and press Start. The timer counts down and sounds an alarm when it reaches zero, even if you switch tabs (the tab title shows the time left). Pause and resume anytime, or Reset to start over. Space starts/pauses.
Counting down to a date or event instead? Make a countdown. Need to time how long something takes? Use the stopwatch.

Timer FAQ
Is the online timer free? Yes — free, with no sign-up and no app to install.
Does it ring if I switch tabs? Yes, it sounds an alarm when it reaches zero, and the tab title shows the time left. For exact timing keep the tab open, as browsers can slow background tabs.
Can I set a timer for a specific length? Type any hours, minutes and seconds, or tap a preset like 5 min or 1 hr.
