Online Timer / Countdown Timer

Type the number of minutes (and seconds, if needed) into the timer fields, then click Start. The countdown begins immediately. When it hits zero, an alarm sound plays and the timer flashes or shows a notification. Click Reset to clear and start over. Useful for cooking, study breaks, workouts, parking meters, exam timing, and any situation where you need a heads-up after a fixed duration of time.

Enter 10 in the minutes field and 0 in the seconds field. Click Start. The timer counts down from 10:00 to 0:00, then plays an alarm. Total setup time is about three seconds. Useful for short breaks, focused work intervals, quick cooking tasks (boiled eggs, pasta water reaching a boil), or any "remind me in 10 minutes" task. Keep the browser tab open so the timer can ring at the right moment.

Set the duration, click Start, and the timer counts down. When it hits zero, the alarm sound plays automatically. Most timers include a volume control and a sound selector so you can pick a noticeable but non-jarring tone. Pick a longer or louder alarm for situations where you might be away from the keyboard, or shorter and softer for quiet environments. The alarm continues until you click Stop or close the tab.

Click the full-screen button on the timer page (or press F11 in the browser). The countdown fills the entire screen with large digits visible from across a room. Useful for classroom activities, presentations, exam timing, and gym workouts where everyone needs to see the time remaining clearly. Press Escape or F11 to exit full-screen mode. The timer keeps counting accurately whether or not it's in full-screen view.

Set a focused work duration — 25, 45, or 60 minutes are common — and click Start. When the timer ends, take a short break, then start it again. Useful for the Pomodoro technique (25-minute work blocks) or longer deep-work sessions. Some study timers loop automatically with built-in break intervals; others require a manual reset. Pick whichever style fits your routine. The audio alarm tells you when the work block is up.

Enter the minutes in the minutes field and the seconds in the seconds field. So 7 minutes 30 seconds means typing 7 in one field and 30 in the other. Click Start. The timer combines them and counts down. Useful when your duration isn't a round number — like a recipe that calls for 4 minutes 45 seconds, or an exam section that runs 17 minutes. Most timers handle hours too if you need longer durations.

That's exactly what the online timer is for. Open the page, set your duration, click Start. No download, no install, no permissions. The browser handles everything. Works on laptops, tablets, and phones. Keep the tab open so the alarm can ring at zero. Quick setup compared to opening a phone, finding the timer app, and setting the time. Useful when you're already at your computer working on something else.
