12:01 AM is the correct way of writing "one minute past midnight" in 12-hr
time.

24 hour time shouldn’t need an AM/PM indicator.

Weird; that seems like a useless complication to add.
There’s really no ambiguity about 12:00 AM/PM. AM and PM toggle the instant the clock strikes 12. So “12:00 AM” is midnight because the time just flipped from PM to AM.

States in legal contracts and for airplane, bus, or trainschedules, though
some schedules use other conventions. Occasionally, when trains run at
regular intervals, the pattern may be broken at midnight by displacing the
midnight departure one or more minutes, such as to 23:59 or 00:01.”

But the beginning of AM/PM is 12, and the end is 11, which is odd to me. I now think the model as a real clock on the wall which use Rome numbers, there are III, VI, IX and XII. So definetly there is no zero hour on the clock. Thanks all.

The ambiguity isn’t the 11 or 12 but what “midnight” refers to. If you say midnight the 30th, what time is that? That’s the issue the style guides are trying to clarify.

Thank you, Jacob. It really was not what I expected. But I will remember it.
