Two 12-Hour Periods

The 12-hr organisation divides the 24 hours of a twenty-four hour period into two periods lasting 12 hours each. The first 12-60 minutes menstruation is designated as am. It runs from midnight to apex. The 2d menstruum, marked pm, covers the 12 hours from noon to midnight.

The abbreviations am and pm derive from Latin:

AM = Ante meridiem: Before noon
PM = Mail meridiem: After noon

Using numbers from 1 to 12, followed past am or pm, the 12-hr clock organization identifies all 24 hours of the mean solar day. For case, v am is early in the morning, and v pm is tardily in the afternoon; 1 am is ane hour after midnight, while 11 pm is 1 hour before midnight.

Ante meridiem is ordinarily denoted as AM, am, a.m., or A.Grand.; postal service meridiem is usually abbreviated PM, pm, p.m., or P.M. Similar many other sources, timeanddate.com uses am and pm, merely the other variants are equally correct and widely used.

What is solar apex?

Midnight and Apex: AM or PM?

The main weakness of the 12-hr system is a widespread confusion most which abridgement should be used for apex and midnight: neither moment can logically be identified as before noon (am) or after apex (pm). For example, the moment of midnight occurs precisely 12 hours after apex on the previous 24-hour interval and 12 hours earlier apex on the post-obit day.

However, most digital clocks and about sources, including timeanddate.com, designate midnight every bit 12 am and noon as 12 pm. Although the precise moment of noon falls in neither category, the hour succeeding it, from 12:00:01 to 12:59:59, is clearly after noon.

To avoid any confusion when referring to the precise moment of apex or midnight, we recommend using the designations 12 noon and 12 midnight instead.

Midnight Confusion

Another source of defoliation is the lack of a engagement designator in the 12-hour system, making it impossible to logically place a correct moment in time when only a date and 12:00 am (midnight) is provided.

Imagine existence asked to choice upward a friend at the airport at 12:00 am on April 13. Would y'all go there at midnight betwixt April 12 and April 13? Or 24 hours afterward?

I way to overcome this problem is to sacrifice accuracy for clarity. Your friend could ask yous to be at the airport at 12:01 am on Apr 13 or, if the post-obit midnight is meant, at 11:59 pm on April 13. Alternatively, the 24-hour format could be used. Hither, 0:00 refers to midnight at the beginning of the day while 24:00 is midnight at the end of the 24-hour interval.

Converting 12-Hour to 24-Hour Format

A 24-hour clock, sometimes referred to equally military time, states the time according to the number of hours that accept passed since midnight. Starting at midnight, hours are numbered from 0 to 24, removing the need for designations like am and pm. For instance, at 23:00, 23 hours have passed since the showtime of the current day.

To convert am or pm time to the 24-hour format, use these rules:

From midnight to 12:59 am, subtract 12 hours.
12:49 am = 0:49 (12:49 – 12)
From 1 am to apex, exercise null.
11:49 am = 11:49
From 12:01 pm to 12:59 pm, do zippo.
12:49 pm = 12:49
From ane:00 pm to midnight, add 12 hours.
ane:49 pm = 13:49 (ane:49 + 12)

Here's how to convert time on a 24-hr clock to the 12-hour organisation:

From 0:00 (midnight) to 0:59, add 12 hours and use am.
0:49 = 12:49 am (0:49 + 12)
From ane:00 to 11:59, just add together am after the time.
11:49 = 11:49 am
From 12:00 to 12:59, only add pm afterwards the time.
12:49 = 12:49 pm
From xiii:00 to 0:00, decrease 12 hours and employ pm.
13:49 = 1:49 pm (13:49 - 12)

Where Is the 12-Hour Format Used?

Most countries around the world today use the 24-60 minutes system. However, the 12-hour format, including am and pm, is officially used in a number of countries, including the United States, Canada (except Québec), Australia, New Zealand, and the Philippines.

Why Does the Twenty-four hours Have 24 Hours?
