How to use the online alarm clock

Watching the clock for the Army Cadets collection can make the last part of the evening feel oddly slow. An alarm set for 7:20 pm lets you concentrate on what you are doing until it is time to leave, rather than checking every few minutes. The collection still falls comfortably before 8:00 pm, so the round hour can remain a useful marker for whatever comes afterwards.

Because Cadets may finish in a busy hall or beside a noisy car park, check where the alarm sound will actually play. A phone or laptop can quietly route audio to headphones left in a bag, making a working alert seem silent to you. Set 7:20 pm, choose the intended sound output and confirm that its volume is audible nearby. If you close this page or allow the phone or laptop to sleep, no alarm will sound, so the Army Cadets collection could be missed.

Once the journey home is finished, keeping the rest of the evening simple can protect the sleep that remains before morning. It may help to have supper, school things and the route home sorted earlier, leaving fewer jobs after 7:20 pm. A second reminder for a sensible winding-down point can also stop the collection from pushing the whole evening later than planned.

Common questions

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 7:20 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.

Do I need an account or an app?

Neither. Choose a time and a sound, press Start, and it runs in this browser tab. Nothing is downloaded, nothing is registered, and closing the page leaves nothing behind on the device.
