How to use the online alarm clock

Waking at 11:29 pm gives you a moment to gather yourself before taking part in a pub quiz. If your team is meeting at the local around 12:00 am, use that half-hour to get dressed, check the venue details and remember the name under which the table was booked. The alarm should bring you into the evening rather than send you rushing straight out of bed.

Your pub-quiz wake-up depends on the device remaining active long enough to play the chosen sound. Set the volume before settling down, then check that battery-saving settings will not put the phone or laptop to sleep first. This browser alarm also needs its page to remain open: if the page closes or the device sleeps, no sound will mark 11:29 pm, and the pub quiz may begin without you. A separate alarm on another device offers useful cover if timing is tight.

A late pub-quiz start can make a bright screen feel harsh immediately after waking. Keep the room light on at a comfortable level before looking at directions or messages, and reduce the screen brightness if it dominates the room. Reading only the details needed for the evening limits unnecessary scrolling; once the meeting place and route are clear, putting the screen aside leaves your eyes time to adjust before you head out.

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.
