How to use the online alarm clock
Getting ready now to collect your teenager from Army Cadets means 11:08 pm can be set aside before keys, coat and directions compete for attention. Set the alarm for this evening, check that the sound is audible, and leave enough time to reach the club without rushing. With 12:00 am approaching, the alert can mark the moment to head out rather than the start of another late-night task.
Your Army Cadets collection will not get its alert if the browser is closed before 11:08 pm, and a sleeping phone or laptop may also stay silent. Keep the alarm page open and the equipment awake until it sounds. A quick sound check while preparing helps confirm the volume, while placing the equipment nearby makes the signal easier to notice over television or conversation.
Before leaving for the club late in the evening, check how the air feels outside as well as the displayed temperature. High humidity can make a mild reading feel close and muggy, while damp air may leave car windows misted. Allow a minute to clear the windscreen, take a light outer layer if the air feels cool, and keep the route home calm as midnight draws near.
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.
