And, the answer for the the question is :
Explanation:
‘A.M.’ is an acronym for the Latin phrase ‘ante meridiem,’ which literally translates to ‘before noon.’ The abbreviation “P.M.” comes from the Latin phrase “post meridiem,” which means “after noon.” “12 a.m.” and “12 p.m.” are unclear and should not be used,” says the Physical Measurement Laboratory, which is part of the National Institute of Standards and Technology and is housed inside the United States Department of Commerce. They advise going with the terms “noon” and “midnight” instead of “noon” and “midnight.”
The terms A.M. and P.M. are used to indicate whether a time is in the morning or the afternoon/evening. These abbreviations are commonly used in English-speaking countries, and they are derived from the Latin words “ante meridiem” and “post meridiem,” which translate to “before noon” and “after noon,” respectively. The “M” in A.M. and P.M. stands for “meridiem,” which refers to the middle of the day or noon.
The use of A.M. and P.M. dates back to ancient times when people used sundials to tell time. Sundials were not very accurate, and they could only provide a general indication of whether it was morning, afternoon, or evening. As technology advanced, clocks and watches were developed, and people began to measure time more precisely.
The 12-hour clock, which is the system used in most English-speaking countries, was developed in the Middle Ages. This system divided the day into two 12-hour periods, with A.M. indicating the hours before noon and P.M. indicating the hours after noon. The use of A.M. and P.M. became common in the 17th century, and these abbreviations have been in use ever since.
there is also a 24-hour clock, which is used in many parts of the world. The 24-hour clock eliminates the need for A.M. and P.M. because it uses a continuous numbering system, with the hours ranging from 0 to 23. For example, 1:00 P.M. would be written as 13:00 in the 24-hour clock.
While the use of A.M. and P.M. is widespread, there are some situations where a 24-hour clock is preferred. In the military, for example, the 24-hour clock is used to avoid confusion and ensure that everyone is using the same system of timekeeping. It is also used in transportation schedules, such as airline and train schedules, to avoid confusion between different time zones.
