How to use the online alarm clock
You have only just woken up, so arriving at the neighbours’ for tea begins with getting yourself moving rather than rushing straight out. Set the alarm for 6:20 pm, then use the time before 7:00 pm to wash, dress and check whether you should take anything across. That leaves a clear boundary between waking and being ready to knock on their door.
Your neighbours will not know that your phone is set to silent, so check how this browser alarm behaves before relying on it for tea. Silent mode may suppress or reduce the sound, depending on the device and browser settings; a quick test lets you confirm that the alert is audible. Keep this page open and the device awake as well: if either is shut down or allowed to sleep, the tea reminder may never sound and you could arrive late.
As nearby homes grow busier towards 6:20 pm, voices, televisions and evening traffic can make a quiet alert easy to miss. Leave the phone on a hard surface close to where you are getting ready, rather than under bedding or inside a bag, so its sound carries. If the street becomes quieter nearer 7:00 pm, listen for the change as a useful cue that it is nearly time to leave for the neighbours’ house.
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 6:20 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.
