Online alarm clock for 6:48 pm
You’re handing the swimming run to someone else, so a 6:48 pm alarm can mark the moment they need to take over. It leaves enough time to pass along the pool address, confirm which bags are packed and mention where pickup happens before 7:00 pm. That clear handover helps prevent a rushed search for goggles or towels as departure approaches.
Because another person is relying on the alert, check its sound before the swimming pickup depends on it. Set a temporary alarm for a minute ahead, keep the volume at a level you can hear and confirm the alert actually plays. Then remove the test and set 6:48 pm. A browser alarm cannot cover the swimming handover if the page is no longer running or the computer has gone to sleep, so use a separate alarm when nobody will be there to keep it active.
With the household shifting from afternoon activities towards dinner, tell anyone nearby that the 6:48 pm sound is for the pool run. Choose a recognisable tone that will not be mistaken for another person’s message, and place the computer where the nominated driver can hear it without startling everyone else. Keeping the packed swim gear near the door also lets the alarm signal departure, rather than the start of another search.
Common questions
Will the alarm still ring if I close the browser tab?
No. The alarm only runs while this tab stays open — closing it, or closing the browser entirely, stops the countdown before it can ring. Keep the tab open in the background if you need it to go off later.
Does the alarm work if my laptop goes to sleep?
Not reliably. If the device sleeps or the screen locks, the browser tab pauses along with it, so the alarm may not fire on time or at all. Adjust your power settings if you're relying on this over a longer stretch.
Do I need to create an account or download anything?
No, there's nothing to sign up for and nothing to install. Pick a time and a sound, press Start, and it runs entirely in this browser tab.
Can I change the alarm sound?
Yes, there's a short list of tones to choose from before you press Start. Pick whichever one you're most likely to actually hear — softer sounds are easier to sleep through than a firm chime or bell.
