Frequently Asked Questions

Can I share a countdown link?

Yes — the timer URL updates with your target date so you can share it and others see the same countdown.

Does the countdown work in other time zones?

Yes — the timer automatically adjusts to the viewer's local time zone.

What is Pomodoro technique?

The Pomodoro technique uses 25-minute focused work sessions followed by 5-minute breaks. After 4 pomodoros, take a longer 15-minute break. It improves focus and prevents burnout.

Does the timer work when I switch tabs?

Yes. The timer uses JavaScript setInterval which continues running when you switch browser tabs. The sound will still play when the timer ends.

Can I use this as an egg timer or meeting timer?

Yes — set any duration using the hours, minutes and seconds inputs. Use the presets for common durations or add time with the +1 min and +5 min buttons.

Using a countdown timer and stopwatch

A browser timer is handy when you do not want to reach for your phone: timing a presentation, a break, an exam practice or a step in a recipe. This tool has a countdown with a sound alert when time is up, a stopwatch with lap times, and Pomodoro presets. It works in your browser with nothing to install.

The Pomodoro technique

The method, developed by Francesco Cirillo, splits work into focused blocks, traditionally 25 minutes long, separated by 5-minute breaks, with a longer break of 15 to 30 minutes after four blocks. Short, fixed blocks make it easier to start a task and harder to drift into email or social media.

Plan the block. Write down one task before you start the timer.
Protect it. If something comes up, note it down and deal with it in the break.
Adjust the length. Some work suits 50-minute blocks with 10-minute breaks; the rhythm matters more than the exact numbers.

Other uses

Meetings and talks: keep presentations and stand-ups to time.
Workouts: use lap times for intervals and rest periods.
Classrooms: show a visible countdown for tests and group work.

Tips

Keep the tab visible. Some browsers slow down timers in background tabs or on sleeping laptops, so leave the tab open for exact timing.
Check the sound. Make sure your device is not muted before relying on the alert.
