Set the alarm clock for 3:34 am

How to use the online alarm clock

An alarm at 3:34 am in the dead of night usually means a red-eye flight, a delivery run, or a newborn's next feed. This sets a browser alarm for 3:34 am that rings through your laptop speakers, so you don't need to fumble for your phone in the dark. Leave the tab open and it'll do the waking for you.

Choose a sound before you press Start — something like a chime or a classic bell tends to work better than anything too gentle. Once it's running, the countdown happens right here in the browser, which means the tab needs to stay open in the background rather than being closed.

Some people use this alongside a phone alarm rather than instead of it: a louder backup through laptop speakers, or a way to set a reminder without touching a phone at all. It won't survive the tab closing or the device sleeping, so for anything critical overnight, keep a second alarm running as well. On a 24-hour clock 3:34 am is written 03:34, and spoken aloud it's twenty-six minutes to four at night. You'll also see it written 3.34 am — a full stop instead of the colon means the same time. Setting the alarm to 3:34 am tomorrow morning works the same way: if the time has gone for today, the count runs through to it.
