How to use the online alarm clock
Waking at 10:29 pm means gathering yourself before you begin setting out the pantomime props. Give your eyes a moment to adjust, then use the time before 11:00 pm to check the stage plan, locate each piece and decide what must be ready first. That keeps a sleepy start from turning into hurried guesswork behind the scenes.
Your props setup could easily stay silent if the alarm sound has slipped into headphones left on a chair or tucked inside a bag. Check the audio output before settling down, and play a brief test if the controls provide one. Do not rely on this browser alarm alone for the props: if its page stops running or the computer sleeps, it will not sound at 10:29 pm, so keep a separate alarm available.
Getting to the venue may take longer late in the evening than the mileage suggests, especially around theatre closing times, station traffic or overnight roadworks. Check the route before returning to sleep and allow for loading the props at the other end. If public transport is involved, confirm the final useful connection; if driving, note where unloading is permitted so the journey does not consume the preparation time before 11:00 pm.
Common questions
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.
What happens if my laptop goes to sleep before 10:29 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.
