- Pause / Resume — click the pause button on any timer to freeze it, resume when ready.
- Fullscreen mode — click the expand icon on any timer for a large projection-friendly display.
- Sound alarm — a beep tone plays when the countdown reaches zero (toggle on/off per timer).

Why Use This Countdown Timer
Whether you're counting down to a product launch, a holiday, a meeting, or just the end of the workday, this timer gives you a clean, distraction-free display. The fullscreen mode is perfect for office dashboards or party screens — no browser chrome, just big numbers.
Multiple simultaneous timers mean you can track several events at once. The share URL feature lets you send a pre-configured timer to a teammate — they open the link and the countdown starts immediately. Everything runs client-side, so there are no server delays and no data leaves your browser.
Frequently Asked Questions
No — the timer runs in your browser tab. If you close the tab or the browser, the timer stops. For long-running countdowns, keep the tab open or bookmark the share URL to reopen it later. The timer will calculate remaining time based on the target when you reopen.
The alarm uses the Web Audio API to generate a beep tone directly in your browser — no external audio files are needed. Some browsers may require you to interact with the page first (click anywhere) before audio can play. The sound can be toggled on or off per timer.
The timer validates that the target is in the future. If you select a past date or time, the "Start Countdown" button will show an error. Pick a future date and time to proceed.
The share URL encodes the target timestamp and timer name as query parameters. When someone opens the link, the timer is automatically created and starts counting down. No data is stored on any server — everything is in the URL itself.
There's no hard limit. You can run as many simultaneous timers as your device can handle. Each timer is lightweight, so even a dozen timers should run smoothly on any modern device.
