How to use the online alarm clock
Getting ahead of the evening, you are preparing to close the curtains before darkness settles outside. An alarm for 10:33 pm marks the moment without making you watch the fading light or repeatedly check the clock. With 27 minutes remaining until 11:00 pm, there is still time to finish what you are doing and have each room sorted before the hour changes.
While you wait to close the curtains, this alarm page can sit behind the page you are currently viewing. Moving it into the background does not cancel the chosen time, although leaving the browser running gives the sound its chance to play. If you close the page or let your phone sleep, the alarm cannot remind you about the curtains, so use the phone’s built-in alarm when you need to put it away beforehand. Keeping the volume audible also avoids an easily missed visual alert.
Once the curtains are drawn at 10:33 pm, a small evening drink or anything already prepared can fit naturally into the remaining routine. A glass of water or a decaffeinated warm drink is less disruptive than starting a full meal close to 11:00 pm. If cooking would involve bright lights, noise or a lengthy clean-up, leaving it until another suitable time keeps this particular reminder focused on closing the house for the night.
Common questions
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.
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.
