Online alarm clock for 7:43 pm
You’re handing the evening river run over to someone else at 7:43 pm, so set the alarm for the agreed changeover rather than leaving them to watch the clock. Seventeen minutes gives the next runner time to check their laces, collect a light and meet you before 8:00 pm, while you finish your section of the riverside path.
Your phone may be on silent while you run, and a browser alarm can be affected by that setting. Check the sound level and test an alarm briefly before putting the phone away; vibration alone can be easy to miss beside traffic or cyclists. Keep a separate backup for the handover, because this browser alarm cannot signal the end of your river run if its page is closed or the phone goes to sleep.
As your changeover approaches, notice where the path becomes quieter and where surrounding noise still masks a signal. By 7:43 pm, commuter traffic may be easing, yet shared riverside paths can remain busy with bikes, conversations and passing boats. Choose a meeting point away from the loudest crossing, keep one ear free if conditions allow, and use a clearly visible landmark so the next runner can spot you even if neither person hears the alarm immediately.
Common questions
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.
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.
