Set an alarm for 11:30 PM
The clock above is already set to 11:30 PM. Press Start alarm and leave this tab open — it will ring at 11:30 PM even if you are working in another tab.
11:30 PM is the middle of the night. If you are setting this for a shift, a feed or medication, use the gradual fade so you are not jolted awake with a full adrenaline response.
Test the sound once so your browser unlocks audio, turn the volume up, and keep the device plugged in with sleep disabled. A browser alarm is only as reliable as the machine it runs on.

Questions about setting an alarm for 11:30 PM
How do I set an alarm for 11:30 PM?
This page is already set to 11:30 PM — press Start alarm and it is armed. If 11:30 PM has already passed today, the alarm is set for 11:30 PM tomorrow. Bookmark this page and the time will be pre-filled every time you come back.
How long until 11:30 PM?
Once you press start, the panel shows a live countdown and the browser tab title updates with the time remaining, so you can check it without switching back to this tab.
Will it work if I close the tab?
No. A web page stops running when its tab closes, when the browser quits, or when the device sleeps. Keep the tab open and the device awake, and set a second alarm if oversleeping would be a real problem.
