Timer settings
Set a custom duration, then choose optional sound and loop behavior.
Online Timer
Start a clear countdown with presets, custom time, sound, loop, and fullscreen mode.
Choose the right timer
Online Timer is a flexible everyday starting point with quick presets, custom time entry, optional sound, looping, and fullscreen. Use the Countdown Timer for the definitive general countdown, or the Timer and Stopwatch when you also need elapsed-time mode.
Open Multiple Timers for simultaneous independent countdowns, the Study Timer for a fixed study block, the Pomodoro Timer for repeated work and breaks, or the Clock and Timer when current local time should remain visible.
Enter one duration
Type a time such as 05:00, or select a minute preset. Start begins the countdown. Pause keeps the current remainder, and Reset reloads the entered duration. Fullscreen enlarges the same active timer rather than opening a separate session.
Use this route for a single general countdown. The Countdown Timer adds direct +1:00 and -0:10 adjustments. Multiple Timers is the better fit when several independent deadlines must run together.
Alarm delivery
The final sound is produced by the browser when sound is enabled. An earlier user action may be required before audio is allowed. Background tabs can update less often, and a sleeping device can delay completion. No active run survives a refresh or closed tab.
