About the 19 minute timer
This page is preset to exactly 19 minutes so nothing stands between you and Start. Teachers use 19-minute countdowns for timed writing, station rotations, quizzes, clean-up races and brain breaks; everyone else uses them for workouts, pomodoro focus rounds, cooking and laundry.
Other popular lengths: 5 minute timer · 10 minute timer · 15 minute timer · 20 minute timer, or the full classroom timer with stopwatch mode and presets.
Why timestamps beat ticks
The countdown sets a target end time once and compares against the clock on every refresh — so tab throttling, screen locks and slow devices can't make it drift or stall. That's the same approach proctoring software uses.
FAQ
How do I start the 19 minute timer?
Just press Start — the countdown is preset to 19 minutes. Use the presets row or the minutes/seconds boxes to change the length first if you need something else.
Does it have an alarm?
Yes — a triple chime plays when the countdown reaches zero and the display flashes “Time's up!”. You can mute it.
Can I use it full screen?
Yes — the Fullscreen button hides everything except the timer, perfect for projectors and smartboards.
Is there a stopwatch too?
Yes — switch to Stopwatch mode to count up instead of down.
Does it work offline?
After the first load, yes — the timer works without internet, so classroom Wi-Fi drops won't stop it.
