The first proper meeting of the day always arrives faster than the morning's admin allows for. Knowing exactly how long is left until 8:57 am is the difference between finishing one more thing and starting something you cannot finish in time. The number here recalculates every second without anything to press or refresh.
Nothing here is stored, sent or remembered. The page works out one number from your device's clock and draws it, and that is the whole of what it does. Closing the tab leaves nothing behind, and there is no history of times you have looked up sitting anywhere afterwards.
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 08:57 removes the problem entirely, because a 24-hour figure only ever points at one instant in the day.
Common questions
What is 08:57 on a 12-hour clock?
The same instant is 8:57 am in writing and three minutes to nine in the morning 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 8:57 am, not a figure worked out when the page first opened.
What happens once 8:57 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.
