Through the summer the only tolerable hour outdoors is the one before the sun clears the horizon, so runs and long rides start at times that would look absurd in November. If 2:45 am is when you mean to be moving, this page counts down to it exactly, which is more use than guessing from the light outside.
This is a display rather than an alarm. Nothing rings, buzzes or notifies at the end, and the page will not interrupt whatever else you are doing. If being interrupted is the point, set an alarm as well and treat this page as the running total you can glance at in the meantime.
Having all three forms in front of you saves a good deal of squinting: 2:45 am for everyday reading, 02:45 for anything printed in timetable style, and quarter to three at night 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 02:45 on a 12-hour clock?
The same instant is 2:45 am in writing and quarter to three at night 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 2:45 am, not a figure worked out when the page first opened.
What happens once 2:45 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.
