How to use the online alarm clock

While you wait for the moment to collect your teenager from Army Cadets, set the alarm for 11:52 pm and keep an eye on the remaining evening. It gives you a clear cue to gather your keys, check the pickup point and leave without repeatedly watching the clock as 12:00 am approaches.

Before relying on the alert for the Army Cadets pickup, test it at a nearby time and confirm that the sound is loud enough to notice. Check your phone’s volume and avoid silent mode, then reset the alarm for 11:52 pm after the trial. Keep the alarm page running on an awake phone; otherwise the Army Cadets pickup alert will not sound. A separate phone alarm is sensible if you might put the handset aside or let its screen remain off for a long while.

Heading out for a late pickup can feel different from an earlier evening journey because damp air often settles after dark. At 11:52 pm, check the local conditions and take a light waterproof layer if the air feels humid or drizzle is possible. Clearing mist from the windscreen before setting off also makes the short drive less hurried, especially when street lighting and reflections on wet roads reduce clarity.

Common questions

Will it still be right when the clocks change?

Yes. It reads your device's local clock, so the move between GMT and BST at the end of March and October is picked up automatically, as long as the computer's date, time and time zone are set correctly.

Can I use this on a phone?

It works in a mobile browser, but phones lock the screen and suspend background tabs far more readily than a laptop does, which can stop the alarm sounding. For anything important, a desktop or a plugged-in laptop is the steadier option.

Does the alarm still work if I close the tab?

No. Everything runs inside this page, so closing the tab — or quitting the browser altogether — ends the countdown there and then. Leaving it open in the background is all it asks, and switching to another tab makes no difference.

What happens if my laptop goes to sleep before 11:52 pm?

The tab sleeps along with it and the alarm will not sound on time, if at all. If you are relying on it, change the power settings so the machine stays awake, or keep a phone alarm running as well.
