How to use the online alarm clock
As you finish what you are doing and leave for an evening jury sitting, a 10:40 pm alarm gives you a clear signal to set off. It leaves a useful margin before 11:00 pm for the walk from the station, finding the correct entrance and passing through security without turning the journey into a last-minute rush.
During the journey, the alarm page may be pushed into the background while you check a map, ticket or message. It can usually continue running there, but browser power-saving and audio controls may affect what happens when the time arrives. If the browser is closed or the phone falls asleep, there may be no sound to remind you about the jury sitting. Keeping the alarm visible and the phone awake, with the volume checked beforehand, makes its behaviour easier to anticipate.
Leaving for a late-evening commitment can make the rest of the night feel tightly packed, so the time after the jury sitting deserves a little space as well. Allow a buffer before any further plan that same day, especially if public transport is less frequent near 11:00 pm. A saved route home, a checked final train and a few uncommitted minutes can prevent one delayed finish from affecting everything that follows.
Common questions
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 10:40 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.
