How to use the online alarm clock
While getting the watering cans and collected rainwater ready, set the alarm for 5:06 pm so the greenhouse is not forgotten when you head outside. Preparing everything beforehand means you can finish another job without repeatedly checking the clock. The alert comes 54 minutes before 6:00 pm, leaving a useful stretch of the afternoon for watering carefully rather than rushing as the hour changes.
Before relying on the alert for the greenhouse, check the sound level with a brief test and confirm that silent mode will not suppress the browser’s audio on your phone. Choose a volume you can hear from the kitchen, shed or nearby room without making it unnecessarily loud. Keep the browser page running and the phone awake: if either stops, the alarm cannot sound, and the greenhouse watering may be missed.
As you prepare to carry the rainwater outside, notice which sounds are likely to compete with the alarm. At 5:06 pm, passing traffic, neighbours returning home, garden machinery or a radio indoors can make a quiet signal easy to overlook. Place the phone away from running water and close enough to hear, then reduce nearby noise shortly before the alert is due.
Common questions
Do I need an account or an app?
Neither. Choose a time and a sound, press Start, and it runs in this browser tab. Nothing is downloaded, nothing is registered, and closing the page leaves nothing behind on the device.
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.
