How to use the online alarm clock
While you watch the last light and wait for the right moment to close the curtains, an alarm at 11:22 pm lets you stop checking the clock every few minutes. This can suit a bright British summer evening, particularly farther north, when darkness arrives surprisingly late. It also leaves a clear marker before 12:00 am without turning the wait into a countdown.
Once the alarm is set, you can move to another browser tab while keeping this page open in the background. Check that your sound is audible first, as browsers may limit activity or audio from a page that has been left behind for some time. Keep the alarm page open and the phone or computer awake; otherwise the reminder to close the curtains may not sound when 11:22 pm arrives.
As the evening settles, notice whether conversation, traffic or television could cover a short alarm tone. At 11:22 pm, a quieter room may make a modest volume sufficient, while an open window near a late bus route may call for a louder setting. Place the phone nearby rather than under clothing or cushions, then let the changing background noise guide the volume you choose.
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.
