How to use the online alarm clock

Finish preparing the fireplace at 8:50 pm, then gather the tools and head away once the hearth is settled. Setting the alarm now gives you a clear stopping point before 9:00 pm, so a final check does not drift into the rest of your evening. Use those last minutes to secure the fireguard, move fuel away from stray sparks and leave the area tidy.

Because you may be leaving the room, check the sound setting before relying on the alarm. Silent mode can prevent the alert from being heard even when the screen appears ready, so choose an audible volume and play a brief test if you are unsure. The fireplace reminder also depends on the browser staying active: if it is closed or the phone or laptop falls asleep, you could walk away without hearing the signal.

After the fireplace is prepared, pause near the doorway and listen before leaving. Household noise often drops towards 9:00 pm as televisions are lowered, washing machines finish and people settle upstairs, which can make an alarm easier to notice—but a crackling fire may still mask a quiet tone. Place the phone where the sound carries into the room you will occupy, without putting it near the hearth or on a soft surface that muffles the speaker.

Common questions

What happens if my laptop goes to sleep before 8:50 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.

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.
