Set the hour and minute for the online alarm clock. The alarm message will appear, and the preselected sound will be played at the set time.

When setting the alarm, you can click the "Test" button to preview the alert and check the sound volume.

You can configure the alarm clock appearance (text color, type, and size), and these settings will be saved; they will be used when you open your web browser next time.

The online alarm clock will not work if you close your browser or shut down your computer, but it can work without an internet connection.

You can add links to online alarm clocks with different time settings to your browser's Favorites. Opening such a link will set the alarm clock to the predefined time.
