How to use the online alarm clock
Finish your lunchtime duty in the school canteen at 2:41 pm, hand over anything still waiting, and leave without watching the clock. The alarm marks the point to clear your place and head out, while still leaving a short gap before 3:00 pm for putting away an apron, washing your hands, or collecting your things.
Because your departure depends on hearing the signal, leave this alarm page open and keep the phone, tablet, or computer awake until it rings. If the browser is closed or the screen sleeps first, the alarm may stay silent and delay your canteen handover. Set the volume high enough to be heard above trays and conversation, then check that the selected time reads 2:41 pm before returning to the final jobs.
Coming out of a busy canteen around midday can mean moving between a cool room and warmer outdoor air. Before leaving, take a moment near the doorway to put away any extra layer needed under strong air conditioning and have water ready if the afternoon is hot. That small pause fits comfortably before 3:00 pm and avoids having to go back through the school once you have left.
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.
