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 7:45 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.
There is nothing to start and nothing to choose. The page reads the clock on your device, works out the gap to 7:45 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.
Having all three forms in front of you saves a good deal of squinting: 7:45 am for everyday reading, 07:45 for anything printed in timetable style, and quarter to eight 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
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.
Will it alert me when 7:45 am arrives?
No. This is a live figure rather than an alarm — nothing sounds, vibrates or notifies at zero. If you need interrupting at 7:45 am, set an alarm alongside it and use this page as the running total.
Do the clocks change here?
No. The UAE has no daylight saving at all, so the offset stays at UTC+4 in every month. When the gap to Europe or North America shifts, it is their clocks that moved, not yours.
What is 07:45 on a 12-hour clock?
The same instant is 7:45 am in writing and quarter to eight 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.
