Use multiple countdowns, a lap stopwatch and a date countdown. Resize the display or go full screen, run timers in sequence or loops, and choose sound and notifications.
Three ways to keep time
- Countdown timers: set hours, minutes and seconds, add names, and control several timers separately.
- Stopwatch: start, pause, reset and record laps with split and cumulative times.
- Date countdown: choose a future date and time and see the remaining duration.
Use these for study sessions, cooking, interval training, presentations or classroom activities. If you also need to keep score, open the online scoreboard.
Sequence and looping countdowns
Sequence mode starts the next timer when the current one finishes. Loop mode repeats the countdown; combined with sequence mode, it returns to the first timer after the final one.
For example, create a 25-minute timer and a 5-minute timer for focus and rest, then enable sequence mode. Enable looping if you want to repeat the pair.
Larger numbers and full-screen display
Display size adjusts the numbers and their display area while Start, Pause and Reset keep their normal size. Side-by-side timers fit the available width, and the ordinary page can scroll naturally. Full screen starts at the largest fitting display size. Countdown and date modes offer classic and flip styles.
Set up end-of-countdown alerts
- Enable system notifications in Settings if wanted, then grant browser permission.
- Choose whether the alarm plays once or keeps playing until stopped.
- Start the timer and keep the page open.
Display size and alert preferences are saved in the current browser.
Frequently asked questions
Why was there no sound or notification?
Notifications require browser support and permission. Audio also depends on browser playback rules and device sound settings. Interact with the page, then check notification permission, volume and the timer settings.
Will it notify me after I close the page?
Do not rely on a closed page to send an alert. Keep it open; device sleep and browser background limits may delay updates or notifications.
