Online alarm clock for 12:22 am
As you finish checking that the sprinkler is off before the local water restriction begins, set the alarm for 12:22 am and leave knowing there is a clear prompt for the final check. The 1:00 am mark is still 38 minutes away, enough time to inspect the tap, controller and any damp patch that suggests a valve is still running.
That late check can easily fail if the alert has quietly been routed to headphones left on a desk or in a bag. Before walking away, confirm that sound is coming from the phone or computer speaker and choose a volume you will notice from where you are finishing up. Because this alarm relies on the browser remaining active and the phone or computer staying awake, it cannot warn you about the sprinkler once either has been closed down.
After the watering check, keep the rest of the night deliberately brief so more sleep remains on the other side of 12:22 am. Put the torch and keys back in their usual places, avoid starting another outdoor job, and return indoors without lingering over the controller. If a second inspection is genuinely needed, decide exactly what must be checked before stepping outside, then come straight back in when it is done.
Common questions
Can I use this on my phone instead of a laptop?
Yes, it works in a mobile browser the same way, but phones are more likely to lock the screen or sleep, which can stop the alarm from ringing. A laptop or desktop tends to be more reliable for this.
Can I set more than one alarm at a time?
This page is built around a single alarm at a time. For multiple alarms, open a separate tab for each one and set a different time in each, keeping every tab open until it's rung.
Why use a browser alarm instead of my phone's built-in one?
Mainly for reliability against silent mode, do-not-disturb, or a phone left charging out of earshot. It's a useful backup or a desk-based alternative, though it depends on this tab staying open rather than running in the background of your phone.
Is there a cost to use this?
No, it's free, with no sign-up and no limit on how many times you set it. It just needs the tab left open until the time you've chosen arrives.
