    You were the one that caused that to be brought up.

    You just can't get your head around time can you?

    0 isn't a number. It's a symbol for nothing (no thing) or the absence of or lack of some thing & it's used as a placeholder.
    Numbers represent things.

    In programming 0 & 1 could just as well be X & R.

    I would say midnight is the next day. On 31st december everyone stays up till midnight to see the new year in hence midnight must be the next day

    According to QI TV program 0 is a even number between 1 and -1

    I think it's strange and really have not formed a view

    Sorry I can't give a QI reference to series and episode

    From memory in past times a day was counted from midday to midday

    I guess Google might have the answer to when it changed to the current system

    But I'm to lazy to check

    Agree

    Changed back at the last chime of midnight

    By my guess would be about 30 to 45 seconds into the next day

    The question sometimes arises whether midnight is written as 2400 or 0000. Military and emergency services personnel refer to midnight both ways. However, digital watches and clocks that display time in a 24-hour format and computer equipment treat midnight as the start of a new day and express it as 0000.Mar 6, 2016

    let us consider the analogue clock

    Midnight is 12 AM (following 11:59:59 PM) - that puts it at the first second of the day.

    But midnight is a zero-length event. It is not a second long.

    The first second of the new day is the first second after midnight.

    Correcting this early post (if it has not been addressed already). Midnight is, indeed, 12:00AM.
    As noon is 12:00PM.

    If I were to clock an event at 2440 hours, it would be assumed to have happened near the end of my duty cycle.
    If I were to clock an event at 0040 hours, it would be assumed to have happened near the beginning of my duty cycle.

    usage, like perspective matters.

    ........................
    meanwhile "midnight' as commonly used is not usually in the middle of the night.
    eg: sunset at 7:32, sunrise at 4:40 the middle of the night would happen after "midnight" as defined as 12:00 am or 2400 hours.
    So, in this example, if the middle of the night is the start of the new day, then midnight would be yesterday.
    ................
    trying to make some sense of it all
    but i can see it makes no sense at all

    and now
    a brief musical interlude:

    "A.M." and "P.M." stand for the Latin ante meridiem and post meridiem, which literally mean "before midday" and "after midday".

    On that basis, 12 noon is midday, but 12:00:00 pm is a contradiction in terms. It sends the mixed message that it is simultaneously midday and after midday.

    As for 0:00:00, midnight, that is exactly 12 hours after the previous midday and exactly 12 hours before the next midday, so is it before or after midday (AM or PM)? There's no set convention on that, so it's probably best just to say 0:00:00 or "midnight" and be done with it.

    This seems to be in line with what the timekeepers at Greenwich say.

    Midnite is the dividing line between days. Before midnite it is Monday; after midnite it is Tuesday. Asking what day midnite itself is is like asking whether the equator is in the northern or southern hemisphere.

    No contradicton in terms... eg... 12 PM... 12:00:00 PM... etc.... means that its some amount of time after midday... such as 12:00:00:01.!!!
