Tips

Frequently Asked Questions about the Online Alarm Clock

No. While the online alarm clock will trigger visually on your screen, you will not hear the sound if your computer’s system volume is muted or your speakers are turned off. We recommend using the "Test" button before setting your alarm to ensure your volume is at an appropriate level.

Typically, no. Most web browsers pause execution when a laptop or desktop enters "Sleep" or "Hibernate" mode to save power. To ensure this alarm for your selected time works correctly, you should adjust your power settings to "Never Sleep" or keep your computer plugged into a power source with the screen active.

No, the browser tab must remain open for the alarm to function. You can, however, switch to other tabs or minimize the browser window. Our online clock is designed to run in the background, but closing the tab or the browser will deactivate the timer.

You need an internet connection to load the page initially. Once the page and the alarm sound are loaded, the alarm uses your computer's internal clock. However, if you refresh the page or lose connection before the sounds are fully buffered, the alarm might not trigger correctly. We recommend a stable connection for the best experience.

The default snooze duration for our free alarm clock is 5 minutes. When the alarm rings, simply click the "Snooze" button in the pop-up window, and the alarm will reset to notify you again after the 5-minute interval.

Yes! You can choose from several different sounds, including Digital Pulse, Gentle Chime, Morning Birds, and a Classic Ring. Use the dropdown menu in the "Sound" section to select your preferred wake-up tone before clicking "Set Alarm."

Our online alarm is highly accurate and synchronizes with your device's system time. Because it uses atomic-time-synced data from your operating system, it is as precise as the clock on your computer or smartphone. It is a reliable way to ensure you wake up on time.
