How to use the online alarm clock
While you wait for the right moment to check the lambing on a Yorkshire farm, set the alarm for 2:24 am and keep the time visible. That gives you a clear cue without repeatedly checking the clock while listening for movement in the shed. If the situation changes, you can reset the alarm; otherwise, the next round hour is 3:00 am.
For a lambing check, the alert needs to be audible over quiet farm sounds and any machinery still running nearby. Check that silent mode is off and raise the alert volume before settling down to wait, then use the preview if one is available. Keep the browser running and the computer awake, because otherwise the alarm cannot sound and the lambing check could be missed. A separate phone alarm is sensible if you may step away from the screen.
Once the ewe is settled, avoid making the waiting area warmer than necessary. Heating left on overnight can make a small office or kitchen feel stuffy by 2:24 am, while air conditioning may be noisy enough to mask an alert. Set a steady, comfortable temperature before waiting, and position the computer where the alarm remains easy to hear without turning the cooling system up and down.
Common questions
Can I change the sound?
Yes, there is a short list of tones to pick from before you press Start. Softer sounds are easy to sleep through, so a firmer bell tends to be the safer choice for anything early in the morning.
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.
