Is 2PM Afternoon? Understanding Time Designations in the US

Time conventions can be confusing, especially in a country as diverse as the United States. One common question that often arises is whether 2PM is still considered afternoon. This article aims to clarify this confusion and provide a broad overview of time designations and traditions in the US.

Before we can delve into the specifics, we must first establish a foundational understanding of time designations. The 12-hour clock system is used widely in the US, and people usually refer to the time using AM (ante meridian) and PM (post meridian) designations. However, the use of military time (24-hour clock) is also common in certain contexts, particularly in the healthcare and transportation sectors.

In this article, we will explore the definition of “afternoon” and the general hours of the day that are considered part of this designation. We will also touch upon cultural factors that influence this classification. Additionally, we will discuss a few unique time-related customs and observances in the US such as daylight saving time and time zones.

By the end of this article, readers will have a better understanding of time conventions in the US and be able to confidently answer the question, “Is 2PM afternoon?”

So, let’s get started and unravel the complexities of time in the United States.

Time Designations in the US

In the United States, time is typically designated using the 12-hour clock system. This means that each day is divided into two 12-hour periods, with AM indicating the time from midnight to noon and PM indicating the time from noon to midnight.

The terms AM and PM are abbreviations of the Latin phrases “ante meridiem” and “post meridiem,” respectively, which translate to “before noon” and “after noon.”

In addition to the 12-hour clock system, the US also uses military time, also known as 24-hour time. This system is commonly used in the military, healthcare, and transportation industries. Military time designates the hours of the day from 00:00 (midnight) to 23:59 (11:59 PM) and eliminates the need for AM and PM designations.

So, is 2PM considered afternoon in the United States? Yes, it is. As noon marks the halfway point between midnight and midnight again, 2PM falls squarely within the PM, or afternoon, designation.

Defining Afternoon

Afternoon is a period of the day that is generally recognized as the time between noon and evening. It is informally defined as the part of the day when the sun is still visible in the sky but is beginning to descend towards the horizon. The exact hours of the afternoon may vary depending on cultural, regional, or individual factors.

In the United States, the afternoon period is typically understood to begin at 12:01 PM and end at 5:59 PM. This convention is widely accepted and used in daily life, but there may be some variation depending on the context. For example, some workplaces or schools may define the afternoon as starting later in the day to accommodate different schedules.

Time-Related Traditions in the US

The United States follows several time-related traditions that impact how people perceive and define afternoon hours. One of the most significant of these is Daylight Saving Time, which is observed in most states across the country.

Daylight Saving Time, or DST, begins on the second Sunday in March and ends on the first Sunday in November. During this period, the clocks are set ahead by one hour to extend the daylight hours in the evening. This means that during DST, 2PM is still considered part of the afternoon, as it falls within the general period of time between noon and evening.

Summer time is another term commonly used in the US to refer to the period during which DST is in effect. During summer time, people are accustomed to longer daylight hours and may schedule events and activities differently than during standard time.

Time zones also play a significant role in determining when 2PM is considered afternoon. The United States has six primary time zones, ranging from Eastern Time to Hawaiian Time. Each time zone is one hour behind or ahead of the preceding zone, with the exception of Hawaii which is two hours behind Pacific Time. The boundaries between the time zones are not always clear-cut, and in some cases, states may observe a different time zone than their geographic location would suggest.

In addition to DST and time zones, the US also has various time-related customs and observances. For example, New Year’s Eve is celebrated with a countdown to midnight in Times Square, New York City, and the 4th of July is marked with fireworks displays across the country.


Understanding time conventions in the US is essential for effective communication and scheduling. Knowing when 2PM is considered afternoon can avoid confusion and misunderstandings. Additionally, being aware of different time-related traditions, such as daylight saving time and time zones, can further enhance one’s understanding of the US time system.
