Alternatively, noon may be written as 午前12時 (12 a.m.) and midnight at the end of the day as 午後12時 (12 p.m.), as opposed to 午前0時 (0 a.m.) for the start of the day, making the Japanese convention the opposite of the English usage of 12 a.m. and 12 p.m. [29]
The "midnight" term can be avoided altogether if the end of the day is noted as 24:00 and the beginning of the day as 00:00. While both notations refer to the same moment in time, the choice of notation allows its association with the previous night or with the following morning. "Midnight" can be augmented with additional disambiguating ...
In the 24-hour time notation, the day begins at midnight, 00:00 or 0:00, and the last minute of the day begins at 23:59. Where convenient, the notation 24:00 may also be used to refer to midnight at the end of a given date [ 3 ] — that is, 24:00 of one day is the same time as 00:00 of the following day.
Midnight (12:00 am local official clock time) was also the sixth hour of the night, which, depending on summer or winter, can come before or after 12:00 am local official clock time, whereas the first hour of the night always begins after sunset, when the first three stars appeared in the night sky.
In these cases, exact and unambiguous communication of time is critical. If someone mistakes 5:00 AM for 5:00 PM in a hospital for example, when medication or other medical treatment is needed at a certain time, the outcome could be dire. Thus 24-hour time (5:00 PM written as 17:00) is used.
The daytime canonical hours of the Catholic Church take their names from the Roman clock: the prime, terce, sext and none occur during the first (prīma) = 6 am, third (tertia) = 9 am, sixth (sexta) = 12 pm, and ninth (nōna) = 3 pm, hours of the day. The English term noon is also derived from the ninth hour. This was a period of prayer ...
Date and time notation in the United Kingdom records the date using the day–month–year format (31 December 1999, 31/12/99 or 31/12/1999). The time can be written using either the 24-hour clock (23:59) or the 12-hour clock (11:59 p.m.), either with a colon or a full stop (11.59 p.m.).
In the modern 12-hour clock, counting the hours starts at midnight and restarts at noon. Hours are numbered 12, 1, 2, ..., 11. Solar noon is always close to 12 noon (ignoring artificial adjustments due to time zones and daylight saving time), differing according to the equation of time by as much as fifteen
