From November to March the morning is the part of the day worth being outside for, and the window closes earlier than newcomers expect. If 10:05 am is when you mean to be at the beach or on the track, the countdown here gives the exact figure, updating every second for as long as the page is open.
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 10:05 am, worked out fresh a second ago rather than when the page loaded.
Having all three forms in front of you saves a good deal of squinting: 10:05 am for everyday reading, 10:05 for anything printed in timetable style, and five past ten in the morning for whatever was actually said down the phone. They are three ways of writing one instant, and mixing them up is easier than it sounds.
Common questions
What is 10:05 on a 12-hour clock?
The same instant is 10:05 am in writing and five past ten 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 10:05 am, not a figure worked out when the page first opened.
What happens once 10:05 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.
