The meaning of a.m. and p.m.

The abbreviations come from Latin and mean:

A.m. – ante meridian – before noon

p.m. – post meridian – afternoon

Germany uses the 24-hour system. In countries like Canada, the USA, and other English-speaking countries, the 12-hour system.

The day is divided into two halves of 12 hours each.

a.m. stands for the period from midnight to morning and p.m. for the afternoon.

a.m.: midnight (0:00) to noon (12:00)

p.m.: noon to midnight (24:00)

These statistics show that the analog or digital display is a decisive criterion when buying a wristwatch.

An analog display eliminates annoying conversions from the 24 to 12-hour system.

The alphabet: In the German alphabet, the letter p comes after a. So p.m. is behind in time.

You also remember AM like this: AM stands for “morning” and thus for the period from 00:00 to 12:00.

PM can be remembered by thinking of PM = Past Midday (afternoon).

Times: noon (am, pm) and 24-hour formats – computer

  • While most countries prefer the 24-hour format, in English-speaking countries and Latin America, the 12-hour format is the most common, twice a day at midnight and midday.
  • To differentiate, an am (ante meridian, Latin for before noon, morning) or a pm (post meridian, Latin for the afternoon) is added.
  • The 12-hour format starts at midnight at 12:00 a.m., one hour later, it is 1:00 a.m.
  • 12:00 p.m. is noon, followed by 1:00 p.m., and the last minute of the day is at 11:59 p.m. There is no 0:00.
  • In the 24-hour format, the day starts at midnight, noon is noon, and the day ends at 11:59 p.m. There is no midnight.

Is noon 12 a.m. or 12 p.m.?

  • Noon and midnight are cases where logically, the time and time do not stick to what they mean, e.g., Ante Meridian and Post Meridian.
  • As suggested in other replies, 12 p.m. and 12 pm-midnight are used to avoid confusion.
  • However, the convention is that midnight means noon after 23:59:59, so the day starts in the morning.
  • In other words, the date on the calendar changes at midnight, and that time is midnight.
  • We can use a different system like that used in the military, the 24-hour clock.
  • The beginning of the day (noon or midnight) is indicated as 0000 and ends at 2359 (corresponds to 23:59).
  • So the hour after noon is indicated by numbers from which we subtract 1200 to get the hour based on 12 hours.
  • Note: for times between 12:00 and 13:00 (except 13:00)
  • With the 24 hour time, 1200 does not need to be subtracted to get the 12 hour time. From 12:00 to 1:00 (except 1:00), we need to add 12 hours to change from 24-hour clock to 12-hour clock.
  • It isn’t effortless, but that’s the way it is.
  • Remembering the calendar thing can help, e.g., H. The date changes, and the day starts. So 12 is midnight.

When do you put AM and PM?

  • AM is the acronym of Ante Meridian, which means before noon and indicates any time between midnight and one second before noon.
  • PM is the acronym for Post Meridian, which means afternoon and indicates any time between noon and one second before midnight.

What time is 12 p.m.?

  • The opposite word indicates the remaining hours of the day and is Ante meridian.
  • This expression is used in the Anglo-Saxon states to tell the time.
  • With the clarification that the 12: 00 PM are the noon while 12: 00 AM are the midnight.
