Online alarm clock for 6:21 pm

Before handing the watering over to someone else, set the alarm for 6:21 pm and agree on which garden beds still need attention. That gives the next person a clear starting point after the day’s heat has eased, rather than leaving them to guess what has already been soaked. If they plan to continue until 7:00 pm, note any pots or dry corners that should be checked before finishing.

Your replacement may hear nothing if the alarm sound has quietly switched to connected headphones. Check the audio destination while arranging the garden handover, then play a quick test sound and leave the volume at a level they will notice outdoors. Closing the page or allowing the phone to sleep can silence the garden reminder completely, so use a separate alarm when missing 6:21 pm would leave the watering undone.

For an afternoon watering changeover, look at how the air feels outside rather than assuming the earlier heat has fully passed. Humid air can make the person taking over feel warmer, while a dry breeze may pull moisture from exposed pots quickly. At 6:21 pm, check the soil below the surface, start with containers that feel dry, and water near the base so the handover remains focused and manageable.

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.
