How to use the online alarm clock
Waking at 11:55 pm for an Army Cadets club pick-up means getting your bearings before reaching for the car keys. The alarm lands just five minutes before 12:00 am, leaving enough time to sit up, check the collection details and make sure you are properly alert before setting off.
For this pick-up, the alarm tone needs to match how readily you wake. A softer sound may suit a quiet house if it reliably brings you round, while a more persistent tone is sensible when deep sleep could make you miss a brief signal. Set the volume beforehand and leave the alarm page running. Because this browser alarm depends on the page remaining active and the phone staying awake, relying on it alone could leave the Army Cadets club collection unattended; a separate phone alarm provides useful backup.
Coming out of sleep into a bright screen can feel abrupt late in the evening, especially in a dark bedroom. Keeping the display dim and using a warmer night setting makes the collection time easier to read without flooding the room with light. The essential details can stay visible in large type, so there is less need to stare at messages while becoming fully awake.
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.
