How to use the online alarm clock
Finish what you are doing and head out to collect your teenager from Army Cadets when the alarm sounds at 11:23 pm. Setting it now gives you a clear stopping point, so a final chore or programme does not make you late. You will still have time to complete the journey before 12:00 am if that matches the club’s collection arrangements.
A late Army Cadets collection can be easy to miss if the television, music or conversation is louder than the alarm. Set your phone or computer volume high enough to test the signal against the actual background noise, and keep the browser running where you can hear it. The Army Cadets alarm will not sound if the page has been closed or the device has gone to sleep, so use a separate phone alarm if missing the collection would leave your teenager waiting.
Before leaving for the club late in the evening, have a glass of water and choose a small, straightforward snack if you are hungry. A large meal may be more convenient after the collection, when you are no longer watching the clock or preparing to drive. Put a drink by your keys rather than carrying an open cup, and leave anything messy or time-consuming until you return home after 11:23 pm.
Common questions
Can I change the sound?
Yes, there is a short list of tones to pick from before you press Start. Softer sounds are easy to sleep through, so a firmer bell tends to be the safer choice for anything early in the morning.
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.
