Online alarm clock for 5:43 pm
Finish checking that every window is shut before the storm, then set the 5:43 pm alarm as the cue to leave. It gives the final walk-through a clear endpoint instead of letting one last latch delay you. With 6:00 pm approaching, there is still room to collect your keys and head out without turning the check into a rushed lap of the house.
Because the windows may take you through rooms away from the screen, confirm where the alarm sound is going before you start. A phone or laptop can quietly route audio to wireless headphones left in a bag or another room, making the alarm seem silent. The windows reminder will not sound after the browser page is closed or if the phone or computer goes to sleep, so it cannot be relied on once you have walked away from it.
Once the windows are secure, the trip ahead deserves a realistic allowance rather than an estimate based only on distance. Around 5:43 pm, afternoon traffic can build near school zones, shopping strips and busy junctions, especially on a weekday. Allowing a small buffer for the road makes 6:00 pm a useful reference point: arrival may take longer than the same drive earlier in the day, even when the route is familiar.
Common questions
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.
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.
