How to use the online alarm clock
Handing the Royal Mail sorting centre opening to the next shift at 2:28 am means leaving them a clear, dependable cue. Set the alarm for the exact handover time, then use the approach to 3:00 am to finish the briefing, confirm who has the keys and pass on anything affecting the first incoming mail.
A sorting centre may already be filled with conveyor noise, vehicle movements or staff conversations when the signal sounds. Choose a volume that can be heard above that background and test it from the place where the person taking over will actually wait. Keep another alarm available as a fallback: this browser alarm could leave the Royal Mail sorting centre without its handover cue if the page is closed or the phone goes to sleep.
Anyone preparing a night-shift handover can make the surrounding light part of the cue as well. Before 2:28 am, switch on a nearby lamp or arrange for the person taking over to stand in a properly lit area, rather than relying on a dim screen. That makes written notes, keys and access details easier to check before the 3:00 am opening work begins.
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.
