How to use the online alarm clock
Wrap up what you are doing and get ready to leave for tea with the neighbours at 4:52 pm. Setting the alarm for this exact time gives you a clear cue to collect your keys, put on a coat and head next door without watching the clock. You will still have a few minutes to settle in before 5:00 pm.
Before relying on the alarm, check where its sound is being sent. Wireless or plugged-in headphones can quietly remain selected even after you have taken them off, leaving the alert unheard across the room. Play a brief sound first, confirm that it comes from the speaker you expect, then set the volume high enough to catch your attention. If the browser stops running or the phone sleeps, the alarm may stay silent and leave the neighbours waiting for tea, so use a separate alarm when punctuality matters.
Leaving in the late afternoon can mean looking from a bright screen into softer outdoor light. As you finish before 4:52 pm, lower harsh screen brightness and avoid spending the final moments staring at small text. Put the phone away once the alarm sounds, gather what you need in the room’s normal light, and give your eyes a moment to adjust before stepping outside.
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.
