How to use the online alarm clock
Break away from what you are doing at 3:43 am to check for overnight frost in the garden greenhouse. The alarm marks a clear stopping point while you are occupied with something else, leaving enough time to inspect the panes, plants and thermometer before 4:00 am without watching the clock throughout.
A greenhouse visit can be missed if the signal is buried beneath a radio, extractor fan or other background noise. Set the volume high enough to remain distinct, then use the preview to judge it from where you will actually be working. This greenhouse frost check also depends on the page remaining active and the handset staying awake; if either stops, no alarm will sound to interrupt the job.
Moving around the house at 3:43 am may wake other people long before their own alarms. Leave a torch, warm layer and back-door key together beforehand, and choose a signal that is audible without being harsh. Keeping shoes away from creaking stairs and closing doors gently makes the night-time greenhouse check less disruptive, while a second, quieter reminder can cover the risk of dismissing the first signal by accident.
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 3:43 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.
