How to use the online alarm clock
As you hand the fireplace duties over at 11:04 pm, confirm who will check the guard, embers and nearby hearth before everyone turns in. An alarm can mark the agreed moment for that final look without interrupting the handover. With 12:00 am approaching, there is still time to explain which fuel has been added and what remains to be done.
Because the next person may keep their phone on silent, check that the alarm has an audible tone and that the volume is high enough to carry into the room. A visual alert alone could easily be missed while logs are being moved or tools put away. If the browser is closed or the computer goes to sleep, the fireplace reminder will not sound, so another dependable alert is needed if nobody will keep it running.
Once the fireplace handover is settled, leave a small buffer before any other task still due this evening. Write down a specific check time rather than relying on “before bed”, and keep the route to the hearth clear of bags or shoes. That spare time allows the person taking over to finish calmly, return the tools to their usual place and handle the next commitment without rushing.
Common questions
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.
Does the alarm still work if I close the tab?
No. Everything runs inside this page, so closing the tab — or quitting the browser altogether — ends the countdown there and then. Leaving it open in the background is all it asks, and switching to another tab makes no difference.
