From December to February the late afternoon is the pleasant part of the day rather than the part to be survived, and it is short. If 3:23 pm is when you mean to be out of the door, this page gives the exact time remaining rather than the guess that usually costs half of it.
There is nothing to start and nothing to choose. The page reads the clock on your device, works out the gap to 3:23 pm, 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.
India runs half an hour off the round numbers, thirty minutes ahead of the Emirates, which catches out anyone arranging a call by counting whole hours. Since the clocks here never shift, the offset to Mumbai is fixed all year — it is the European and American ones that move underneath you.
Common questions
What is 15:23 on a 12-hour clock?
The same instant is 3:23 pm in writing and twenty-three minutes past three 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 3:23 pm, not a figure worked out when the page first opened.
What happens once 3:23 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.
