The traffic on Sheikh Zayed Road does not build gradually so much as arrive, and leaving ten minutes late costs far more than ten minutes. This page tracks the precise time left until 9:04 am, which makes the decision about whether to finish the coffee or pick up the keys a good deal easier to make.
There is nothing to start and nothing to choose. The page reads the clock on your device, works out the gap to 9:04 am, and redraws it every second for as long as it is open. Leave it in a background tab if you like; the number will be current whenever you look back at it.
Plenty of phones and dashboards default to a 24-hour display regardless of how people around them actually speak, so 09:04 may well be the figure staring back at you while 9:04 am is what anyone would say out loud. Neither form is more correct; they are just aimed at different readers.
Common questions
What is 09:04 on a 12-hour clock?
The same instant is 9:04 am in writing and four minutes past 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 9:04 am, not a figure worked out when the page first opened.
What happens once 9:04 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.
