Preset and Custom Durations

One-click presets for 1 min, 5 min, 25 min Pomodoro, 30 min, and 1 hour, plus a fully custom hours/minutes/seconds input.

Pause / Resume / Reset

Stop the timer when something interrupts you, pick up where you left off, or reset back to the original duration.

Visual Progress Bar

A progress bar shrinks as the timer counts down — easier to glance at than a digital readout when you are deep in another task.

Frequently Asked Questions

Yes — JavaScript timers continue running in background tabs, though the browser may throttle very short intervals to save battery. For a 5-minute or longer countdown the result is accurate to within a second or two.

The Pomodoro Technique is a time-management method invented in the 1980s that breaks work into focused 25-minute sprints separated by 5-minute breaks. Every fourth break is longer (15–30 minutes). The 25-minute preset is set to that conventional sprint length.

Most browsers respect the tab mute setting, so a muted tab will not play sound. The visual notification (progress bar at zero, page title flash) still works. For a guaranteed alert, also enable browser notifications.

The current page runs a single timer. For multi-timer needs, open the page in multiple tabs — each tab has its own independent state.

JavaScript timers are accurate to within a few milliseconds, which is more than precise enough for everyday use. For high-precision timing (sub-millisecond), use the [Age Calculator](/tools/age-calculator) which works at the date level rather than the second level.

The timer state is lost. There is no persistence between sessions because most countdown use cases are short and immediate. For long-term countdowns to events days or weeks away, set a calendar reminder instead.
