How to use the online alarm clock

Pause what you are doing at 6:06 pm and set this alarm so you can break away in time to meet the engineer checking your gas boiler. With 54 minutes until 7:00 pm, you can finish the immediate task, clear a route to the boiler and find any service paperwork without repeatedly watching the clock.

Your boiler appointment depends on hearing the alert, so consider whether this phone or computer may fall asleep before 6:06 pm arrives. Keep the browser page open, leave the machine awake and turn the sound up to a level you will notice from the next room. A browser alarm cannot interrupt your gas boiler preparations if its page has been closed or the machine has gone to sleep. For extra confidence, use a separate phone alarm as a backup.

Before stepping away to greet the engineer, check how the late-afternoon air feels outside rather than judging it through the window. British humidity can make a mild reading feel clammy, while a cooler breeze may reach the hallway as the front door remains open. Keep a light layer nearby, and close internal doors if damp air is likely to drift towards the boiler area during the visit.

Common questions

What happens if my laptop goes to sleep before 6:06 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.
