How long until 12:12 am?

Countdown to 12:12 am according to your device's time.

 
 

Through the summer the only tolerable hour outdoors is the one before the sun clears the horizon, so runs and long rides start at times that would look absurd in November. If 12:12 am is when you mean to be moving, this page counts down to it exactly, which is more use than guessing from the light outside.

The clock it uses is your own — whatever local time and zone the device is set to. In the Emirates that means Gulf Standard Time, four hours ahead of UTC, year in and year out. Travel with the same laptop and the count follows the new local time once the machine has picked it up.

Twelve o'clock is where the 12-hour clock is weakest: 12 am and 12 pm are read the wrong way round often enough to cause real trouble with bookings and deadlines. Writing the same moment as 00:12 removes the problem entirely, because a 24-hour figure only ever points at one instant in the day.

Common questions

What is 00:12 on a 12-hour clock?

The same instant is 12:12 am in writing and twelve minutes past twelve at night out loud. Anything from 13:00 onwards loses twelve to give the pm figure, which is the only sum involved in moving between the two.

Does the number update by itself?

Yes. It is recalculated every second from your device's clock, so nothing needs refreshing or restarting. Whatever is on screen is the current gap to 12:12 am, not a figure worked out when the page first opened.

What happens once 12:12 am has passed for today?

The count rolls over and carries on towards the same time tomorrow. That happens on its own at the moment the time passes — the page does not need reloading and there is nothing to reset by hand.

Which clock does the countdown use?

Your own. It reads the local time and time zone from the device in front of you, which in the Emirates means Gulf Standard Time, UTC+4. Travel and the count follows whatever the device picks up.
