Errands at this time of day get wedged between other things, and the useful question is not what time it is but how much of the middle of the day is genuinely left. This page answers that against 12:03 pm exactly, updating on its own for as long as it stays open on a screen somewhere.
One number, counting down: hours, minutes and seconds together. No button to press first, no options to get right, no settings screen hiding a default that turns out to be wrong. Whatever it says is the current distance to 12:03 pm, worked out fresh a second ago rather than when the page loaded.
Plenty of phones and dashboards default to a 24-hour display regardless of how people around them actually speak, so 12:03 may well be the figure staring back at you while 12:03 pm is what anyone would say out loud. Neither form is more correct; they are just aimed at different readers.
Common questions
What is 12:03 on a 12-hour clock?
The same instant is 12:03 pm in writing and three minutes past twelve in the afternoon 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 12:03 pm, not a figure worked out when the page first opened.
What happens once 12:03 pm 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.
