Online alarm clock for 11:21 pm

You’re handing the cricket-club pickup to someone else at 11:21 pm, so set the alarm while you confirm who is collecting the teenager after their shift. The alert leaves enough time for a final message, finding the car keys and checking the club entrance before 12:00 am, without relying on memory during the handover.

For this pickup, check the phone’s sound settings after choosing 11:21 pm and leave the alarm page visible. Silent mode can suppress what you expect to hear, so raise the alert volume and test it before settling down. Keep the page open and the phone awake; otherwise the alarm cannot sound, and the cricket-club pickup could be missed even though the time was set correctly.

Outside the cricket club, voices, doors and departing cars may still cover a quiet alert, but the surroundings often become noticeably calmer as midnight approaches. Put the phone on a hard surface nearby so vibration adds a clear rattle, rather than leaving it under clothing or in a bag. If another person is taking over, agree on one short confirmation message when the alarm sounds, giving you a clear sign that the late-evening pickup is underway.

Common questions

Can I set more than one alarm at a time?

This page is built around a single alarm at a time. For multiple alarms, open a separate tab for each one and set a different time in each, keeping every tab open until it's rung.

Why use a browser alarm instead of my phone's built-in one?

Mainly for reliability against silent mode, do-not-disturb, or a phone left charging out of earshot. It's a useful backup or a desk-based alternative, though it depends on this tab staying open rather than running in the background of your phone.

Is there a cost to use this?

No, it's free, with no sign-up and no limit on how many times you set it. It just needs the tab left open until the time you've chosen arrives.

Will the alarm still ring if I close the browser tab?

No. The alarm only runs while this tab stays open — closing it, or closing the browser entirely, stops the countdown before it can ring. Keep the tab open in the background if you need it to go off later.
