How to use the online alarm clock

Waking at 12:46 pm for a trade union meeting leaves little room for a slow start. The alarm marks the moment to sit up, check where the meeting is being held and gather any papers needed before 1:00 pm. Keeping those first actions simple can make the change from sleep to participating feel less abrupt.

A trade union meeting may call for a gentle sound if other people are nearby, while a more insistent tone suits someone likely to drift off again. The chosen tone can be tested at the current volume before the alarm is left running. This browser alarm will not sound if its session has ended or the phone is asleep, so relying on it that way could mean missing the union meeting; a separate phone alarm provides sensible cover.

Someone heading into a midday union meeting can use the remaining preparation time for a glass of water and a small, familiar snack if needed. A large lunch is easier to leave until afterwards, especially when eating it would take attention away from checking the agenda or joining on time. Tea or coffee may fit the routine, but it is worth allowing enough time to finish the drink without carrying a hot mug into a community hall or workplace meeting room.

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.
