How to use the online alarm clock
You are halfway through a job beneath the railway arch when the 11:50 am alarm tells you to put the tools down and open the workshop. It gives you enough time to step away from the bench, clear the entrance and have the doors ready for 12:00 pm without relying on a hurried glance at the clock.
Machinery, passing trains and a radio can swallow a browser alarm that sounded obvious during a quiet test. Choose a volume that stands out from the workshop’s usual background noise, then listen from the furthest place where you might be working. A silent workshop cue will not pull you away from the job if the browser has stopped running or the computer has gone to sleep, so a separate backup is sensible when opening at noon cannot slip.
If this late-morning alarm follows a short sleep after an overnight repair, decide before 11:50 am whether opening the workshop ends that rest or merely interrupts it. Keeping any later sleep period clearly separate avoids turning the alarm into repeated snoozes while customers wait outside. Leave enough time after unlocking to finish essential opening tasks before settling down again, and use a second alarm for the planned waking time.
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 11:50 am?
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.
