How to Set Your Online Alarm for 12:20 PM
This page makes it simple to set an alarm for 12:20 PM. The settings below are pre-filled for 12:20 PM, but you can easily adjust them if needed. Follow the steps to activate your alarm.
Setting an Alarm
- Choose Time: This page has pre-selected 12:20 for you.
- {{ _("Add a Label (Optional):") }} We've suggested a label for you: "Alarm for 12:20".
- Select Sound: Choose your preferred alarm sound from the "Sound" dropdown. You can click the "Test" button to hear a preview.
- Set Alarm: Click the "Set Alarm" button. The display will change to show your set alarm time and a countdown. If an alarm is already set, this button will update it.
When an Alarm is Set to 12:20
- {{ _("View Active Alarm:") }} The screen will show the label and 12:20 for your active alarm, along with how much time is left until it rings.
- Edit Alarm: To change the time, label, or sound of an active alarm, simply adjust the inputs in the "Edit Current Alarm" section and click "Update Alarm".
- Stop/Cancel Alarm: If you need to cancel the alarm before it goes off, click the "Stop Alarm" button in the "Alarm Active" section.
When the Alarm Rings

Tips
- Test Your Sound: Always use the "Test" button to ensure your chosen sound works and the volume is appropriate.
- Browser Permissions: Some browsers might require you to interact with the page (e.g., click a button) before they allow sound to play automatically. Setting the alarm usually counts as an interaction.
- Keep Tab Open: For the alarm to work, this browser tab needs to remain open. It can be in the background.
- Persistent Alarm: Your last set alarm (time, label, sound) is saved in your browser. If you close and reopen the tab, it will try to reload the active alarm if it hasn't passed yet or isn't currently ringing.
