Online alarm clock for 1:29 pm
Before you need to head out, set the 1:29 pm alarm as an early reminder to check whether the car has become too hot in the sun. That leaves time to open the doors, move it into shade or fit the windscreen shade before your planned departure. If you are aiming to leave at 2:00 pm, the reminder gives you a practical buffer rather than making the heat check part of a rushed exit.
Your car check depends on noticing the alarm, so confirm that sound is allowed and the volume is audible before relying on it. Silent mode can leave the alert visible but unheard, especially when the phone is in a bag or another room. Keep the browser running and the screen device awake enough to operate: if the browser is no longer active or the device sleeps, the car reminder may never sound.
For a midday check at 1:29 pm, reduce the glare before you approach the parked car. Put sunglasses somewhere easy to reach and position a windscreen shade earlier, while the light is easier to manage from outside. If shade moves across the driveway or car park before 2:00 pm, choosing that spot in advance can make the inspection and departure less uncomfortable.
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.
