Online alarm clock for 12:48 pm
Finish the junior primary swimming lesson at 12:48 pm, gather the kickboards and towels, and get the children moving towards the change rooms. Setting the alarm now gives the group a clear cue to leave the pool area before 1:00 pm, without repeatedly checking the clock while counting swimmers and collecting stray goggles.
As the last swimmers climb out, check where your phone is sending its audio. Headphones can remain connected inside a bag, so the alarm may play there without you noticing it beside a noisy school pool. Disconnect them or test the sound before continuing with pack-up. For the swimming lesson alarm to help with departure, this page must remain open and the phone must stay awake; if either stops, no alert will sound.
Moving a class indoors around midday can mean crossing from bright outdoor glare into a dim corridor or change room. Before 12:48 pm, increase the screen brightness enough to see the alarm status at a glance, then place the phone where direct sunlight will not wash out the display. Once everyone is inside, lower the brightness again so the screen is comfortable to check while marking off the group.
Common questions
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.
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.
