Online alarm clock for 12:58 am

Finishing up and leaving before the last bus calls for a firm reminder, not another glance at the clock. An alarm set for 12:58 am marks the moment to pack away what you are doing, collect your keys and head out. With 1:00 am almost here, there is little room for one more task if missing that bus means relying on a taxi.

Moving to another app after setting the alarm can leave this page running in the background, although some browsers may restrict its activity after it has been out of view for a while. Keep the browser available and check that sound is permitted and audible. If the browser is closed or the phone goes to sleep, the alarm may not sound, and the last bus could leave before you realise the time.

Leaving the house around midnight can disturb people who are already asleep, especially when an alarm carries through a quiet home. Use a volume that you can hear nearby without waking housemates or family in other rooms, and keep your bag, shoes and keys together beforehand. That makes the 12:58 am signal a cue for a quiet exit rather than a scramble through cupboards and hallways.

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.
