Online Alarm Clock

Set a time and the alarm sounds when the clock reaches it. Choose from multiple alarm tones. The alarm works in your browser — keep the tab open for it to trigger. You can set multiple alarms for different times.

No. The alarm requires the browser tab to remain open and active. Some browsers may also silence audio in background tabs. For reliable alarms, keep the tab visible or use your device's native alarm app for critical wake-up times.

The current version supports one-time alarms. Set a new alarm each time you need one. For daily recurring alarms, your phone's built-in clock app is more reliable as it works even when the browser is closed.

Choose from classic alarm beep, gentle chime, rooster crow, digital tone, and nature sounds. Volume is controlled by your device's media volume. Test the sound before relying on it for important wake-up calls.

For countdown timing, use the dedicated Countdown Timer or Egg Timer tools. The alarm clock is designed for setting a specific clock time (e.g., 7:30 AM), while timers count down from a duration (e.g., 25 minutes).
