1 PM is definitely in the afternoon division, expressed as 1 PM. 1 in the morning, for that matter, is written as 1 AM. PM denotes times during the afternoon and evening, while AM denotes times during midnight and the morning. Both PM and AM are very good ways to indicate time.

In the United States, 12-hour clock format is used while in the United Kingdom, 24-hour clock format is used.

The 12-hour format

The 12-hour clock format is used to identify the hours of the day. All 24 hours are identified by numbers 1 to 12, followed by AM or PM.

AM is the first half of the day. It starts at midnight and runs throughout the morning. It ends at 11:59 PM. ..

The second half of the day is the time that the sun sets. The hours of the second half of the day are denoted with PM (example: 12 pm, 1 pm, and so on). Hours denoted by PM start at 12 noon, run through evening and night, and end at 11h59 at night.

AM and PM are abbreviations that derive from the Latin terms; ante meridiem (AM), meaning before noon, and post meridiem (PM), meaning afternoon. ..

Both AM and PM are denoted in various ways. AM can be written as a.m, am, and A.M. PM can be denoted as p.m, pm, and P.M. ..

Why Are These Terms Confusing?

Before noon is typically used to refer to the time before sunrise, while afternoon is typically used to refer to the time after noon. ..

AM hours begin at 12:00am on the previous day, and start at 12:00pm on the current day. ..

Many people prefer to use noon as the time of day, and not afternoon, for example. This is because people are more likely to be confused by using two different time periods together.

Another confusion occurs when using the term midnight. For instance, when someone calls you over the phone at 12:01 a.m. on Tuesday, are they calling at 12:01 a.m. on Tuesday or 12:02 a.m.? There is no precise moment of “midnight” according to UTC time standards.

The 24-hour format

In the 12-hour system, the hours of the day are identified with numbers 0 through 12. There is often an “h” to separate the hour and minutes (example: 12h30), or “:” (example: 12:30). The “h” or “H” stands for hours. In the 24-hour format, the hours of the day are identified with numbers 0 through 23. There is often an “h” to separate the hour and minutes (example: 24h00), or “:” (example: 24:00). The “h” or “H” stands for hours.

Morning hours

The 24-hour period begins at 00H00 hours and ends at 23h59.

In the 24-hour time format, the morning hours are written as 12am, midnight, and 00h00. The morning hours last until 11h59. ..

Afternoon and evening hours

In the 24-hour clock format, afternoon hours start at the 12th hour of the day, that is, 12 hours after midnight or before midnight.

After 12 hours, the time is written as 1pm. After 13 hours, it is written as 1:00pm. After 14 hours, it is written as 1:00pm. After 15 hours, it is written as 1:00pm. After 16 hours, it is written as 12:00am. ..

The last hour of the day is the time that ends when the 23rd hour ends. After 23h59, it’s the 24th hour, or midnight. This begins a new day at 00h00.

The president of the United States, Donald Trump, announced on Twitter that he would be imposing tariffs on steel and aluminum imports from Canada and Mexico. This move is part of Trump’s plan to revive the economy and reduce the country’s trade deficit. The tariffs will apply to all goods imported into the United States, regardless of whether they are made from domestic or foreign sources.

You can convert AM/PM hours to 24-hour format by using a time converter. This will make it easier to understand when dealing with the 12th hour.

The United States is switching from 12-hour to 24-hour time. This change will go into effect on November 1st. ..

To convert to 24-hour format, you add 12 to the hours. For example: to convert 1 pm, add 12 to 1. The answer is 13h00.

When converting between the 24-hour clock and the 12-hour clock, be sure to use the correct form for the time of day. For example, 12pm becomes 12 PM, and 12am becomes 12 AM. ..

The 12-hour system is written as 12h00, whereas in the 24-hour system it is 00h00. The 12-hour system is more convenient for people who need to be able to stay on track throughout the day.

From 24-hour to 12-hour

To convert a time from one system to another, simply subtract 12 from the time in the desired system and divide the result by 12. For example, 2pm in the 12-hour system is 14 – 12 = 2, so 2pm is 8pm in the 24-hour system. ..

The 12-hour system is a time-based system, and the rules for dealing with conversions between different time systems apply differently when converting between the 12-hour system and another time system. In the 12-hour system, conversions between different time systems are made using PM (12h00PM). In other words, in the 12-hour system, adding one hour to a number will result in adding one day to that number; subtracting one hour from a number will result in subtracting one day from that number. This is true even when converting between different time zones; for example, when converting from UTC to PST, adding an hour will add one day to the number and subtracting an hour will subtract one day from the number.

Many countries use either or both systems. 1pm is 1pm in the afternoon, and 1am is 1am. You can also calculate the time yourself by applying aforementioned techniques.
