How to use the online alarm clock
Pause what you are doing and set the alarm for 10:59 pm, so you can break away in time for the start of the Proms at the Royal Albert Hall. It gives you a clear cue to put the task aside, find the broadcast or take your seat before 11:00 pm arrives.
Because this reminder is tied to the Proms, leave the browser running somewhere it will remain awake until it sounds. If the computer or phone goes to sleep, or the browser is closed beforehand, the Proms alert will not ring and you could carry on with your task past the opening. Keep the page active, set the volume at a level you can hear, and use a separate alarm as a fallback if missing the start would matter.
Anyone else in the house may already be settling down by late evening, so choose a sound that reaches you without carrying through every room. Headphones are unsuitable if you might take them off while working; a nearby speaker at moderate volume is more dependable. Once the alarm sounds, silence it promptly before switching to the concert, especially if children or an early riser are asleep.
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 10:59 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.
