Set any timer and start counting down instantly.
The Countdown Timer lets you set any duration and count down with a clear visual display. Use it for cooking, studying, workouts, presentations or any timed task. It works in your browser — no app needed.
Type a number into the hours, minutes and seconds boxes — or click one of the preset chips for common durations like 5, 10, 15, 25 or 60 minutes. Click Start and the digits begin counting down. Pause freezes the timer; Reset clears it. When the countdown hits zero a chime plays and the page flashes so you notice even from another tab. The timer keeps ticking accurately even if the tab is in the background, because it tracks the wall-clock end-time rather than counting frames.
Use a countdown when you have a fixed duration to fill — a HIIT round, a presentation slot, an oven check, a shower limit. Use a stopwatch when you want to measure how long something takes from a standing start. Countdown timers are particularly useful for time-boxing: assign yourself 25 minutes for a single task, set the timer, and stop the moment it rings. The discipline of a hard end-time stops tasks expanding to fill all available time.
3 minutes for boiled eggs, 5 minutes for a quick break, 7 minutes for a power workout, 20 minutes for a focused chunk, 25 minutes for a Pomodoro work block, 45 minutes for a school period. The preset chips cover the most common; everything else can be typed manually.
