How to use the online alarm clock
Before handing the last task to a colleague, you need 5:37 pm to mark when it is time to leave for the parent-teacher meeting. The alarm gives the changeover a firm stopping point, so a final explanation does not quietly stretch towards 6:00 pm. Keep anything the other person needs close by, then you can finish the handover without repeatedly checking the clock.
Because the alert may be waiting while you talk through unfinished work, use it on a phone or computer that will remain awake and audible. Closing this page or allowing the device to sleep means the alarm cannot sound, which could leave you late for the teacher meeting. Check the volume before beginning the handover, and avoid relying on headphones that you might remove while speaking to your colleague.
As the handover ends, the afternoon light can make papers, keys and a packed bag surprisingly easy to overlook, particularly on a gloomy British day. Switch on a nearby lamp before the discussion starts and place everything needed for the meeting within its pool of light. When 5:37 pm arrives, that visible group provides a quick departure check and reduces the chance of searching a dim room while the minutes towards 6:00 pm disappear.
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.
