Online alarm clock for 8:47 pm

Finishing your evening run along the river at 8:47 pm gives you a clear point to leave the path, slow to a walk and head home. Set the alarm for 8:47 pm if that is your planned finish, while 9:00 pm can serve as a simple fallback marker when the route or riverside exit takes longer than expected.

During the run, the alarm page may slip behind a map, music player or message without disappearing from view altogether. It can remain set while another browser tab is in front, but keep the browser running and your phone awake enough to sound. The alarm cannot reliably mark the end of your riverside run after the browser has been dismissed or the phone has gone to sleep, so a built-in phone alarm is a sensible backup when timing matters.

Leaving the river in the evening is easier when the final stretch is not weighed down by a large meal. A light snack beforehand may suit a short outing, and carrying water is practical on warm Australian evenings; save a heavier dinner and alcoholic drinks until after you are home. At 8:47 pm, take a few sips, walk the last section and let your breathing settle before eating.

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.
