Is midnight today or tomorrow?

What's Illogical? There is a point in time identified as "midnight" and marks a transition from one day to the next. The point (since it is infinitesimally small like all other points) does not lie on either side of the timeline. Everything else is just semantics. You can define that point however you want:

"Midnight" = "00:00 tuesday" = "24:00 monday" = "moment Cinderella turns into a pumpkin" = "??" ...

We are discussing a communication issue, not a logic issue. We can choose anything but to avoid confusion, it's best to choose a standard definition for that specific (logical)point.

When I was a lecturer, I would sometimes have electronic assignment submissions where I had to specify a due date and time.

Midnight at the end of the due date seemed the obvious choice for the cutoff time, but equally obvious (due to the odd nature of our time system) was the confusion that would result if I specified a due time of 12:00am dd/mm/yyyy.

The (still obvious) solution? Due time: 11:59pm

It is a matter of communication & logic.
There's no transition until the next day begins.
Of course the point lies on 1 side (day?) or the other. How small a point is has nothing to do with it. There is no point in time which is between 2 days. There is no point in time which is shared by 2 days.
You continue saying 00:00. There is no 00:00 point in time. Zero is nothing.
It's best to use a term & definition which makes sense.

That was wise & practical considering the mindless mess you had to deal with.
We shouldn't have to deal with it tho.

Well, the system is odd, but the logic behind midnight being 12am is quite clear.

11:59 pm is the 60th minute - a digital clock reads 11:59 for the entirety of that 60th minute.

And one minute past midnight is 12:00:01 am, right?

If you were designing a digital clock for public consumption with 12 hour time, would time would it display at a nanosecond past midnight?

It's a kind of tricky question if one thinks the beginning of a day is noon.

11:59 is not a minute. It is a point, the last point in time of the 59th minute.
A digital clock which shows seconds reads 11:59:01 (11 hours 59 minutes 1 second), 11:59:02 (11 hours 59 minutes 2 seconds), 11:59:03, 11:59:04, ... ... ... 11:59:57, 11:59:58, 11:59:59 (11 hours 59 minutes 59 seconds), 12:00:00 (12 hours) for the 60th minute.
I would not design a clock with 12 hour time mode.

0000 = next calendar day

There is no 0000. Zero = nothing. No thing. No time. No point.

By definition. Same way I know what 1 is. 00:00:01 is 1 second. 00:00:00 is zero second is no second is nonsense.

Coincidently, the previous post is my #2460, 24 & 60 being such significant numbers in our time measuring. Leftovers from Babylonians.
We should have a base 10 time measurement.
