Online alarm clock for 8:46 pm

Midway through preparing the fireplace for a cold night, you may have ash to clear, logs to bring in or a fireguard to position before you can step away. Set the alarm for 8:46 pm, so the signal gives you a firm stopping point instead of letting the task drift towards 9:00 pm. That leaves the round hour free for whatever follows.

A crackling fireplace, an extractor fan or the television can easily mask a quiet alert, so choose a sensible alarm volume and test it from the part of the room where you are working. Keep the sound clear rather than merely loud, and avoid placing speakers behind furniture. The fireplace reminder depends on the browser continuing to run until 8:46 pm; if it stops beforehand, no signal will pull you away from the job. Use a separate alarm if you need a fallback.

Once the grate and surrounding floor are tidy, evening light can make small embers or scattered tools harder to spot. Before settling elsewhere, switch on the main room light and check the hearth from more than one angle. Leave a lamp on near the fireplace until everything has cooled and the fireguard is secure, rather than relying on the fading glow from the fire.

Common questions

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.

What happens if my laptop goes to sleep before 8:46 pm?

The tab sleeps along with it and the alarm will not sound on time, if at all. If you are relying on it, change the power settings so the machine stays awake, or keep a phone alarm running as well.
