Midnight is the term used to describe a specific point in time on the 24-hour clock indicating the exact moment when one day ends and the next one begins. The word ‘mid’ indicates the middle of something, and in this particular case, it marks the mid-point of the 24 hour cycle.
Historically, the concept of marking time in hours dates back to the ancient civilizations of Greece and Egypt. However, it was the Romans who first divided the day into two 12-hour periods, with midday and midnight serving as the transitional moments. These periods were referred to as ante meridiem (a.m.) and post meridiem (p.m.).
The term “midnight” itself has its roots in the Anglo-Saxon era of England, where it was referred to as “midt-niht,” meaning “middle of the night.” It served as a point of reference for people who needed to know when to eat, sleep, or tend to their duties based on the time of the day.
Today, midnight continues to be an essential time marker. It is a critical moment for various fields and industries such as astronomy, astrology, and navigation. For example, astronomers study celestial events such as the movements of the planets, comets, and stars, and often specify the time of their occurrence in relation to midnight.
Midnight is called such because it marks a special moment of transition between two different days, with roots in ancient civilizations and an important reference point in various fields of study.

Why is it 12 pm and not 12 am?
The reason why it is 12 pm and not 12 am is due to the nature of timekeeping and the way that we have divided our day into two separate 12-hour periods. These two periods, known as a.m. and p.m., refer to ante meridiem (before noon) and post meridiem (after noon). Noon is the exact midpoint of these two periods, so it is neither before noon nor after noon, but exactly at noon.
This system of timekeeping dates back to ancient civilizations like the Egyptians and Babylonians, who used the sun’s position in the sky to determine the length of a day. However, it wasn’t until the 16th century that the 24-hour clock was introduced in Europe, which helped standardize timekeeping and reduce confusion caused by varying local times.
In this system, midnight is considered the beginning of a new day, so it is designated as 12 am. Conversely, noon is the middle of the day, and therefore it is designated as 12 pm. If we were to label noon as 12 am instead, it would cause confusion because it would imply that noon is the beginning of a new day, which it is not.
So in summary, the reason why it is 12 pm and not 12 am is simply because noon is the middle of the day and not the start of a new day.
Why is 12 PM called noon?
The term noon originated from the Latin word ‘nona hora,’ which means ‘ninth hour.’ In ancient Rome, the first hour of daylight was around 6 o’clock in the morning. Therefore, the ninth hour would fall around 12 noon as they used a 12-hour clock system. Over time, the term noon evolved into referring to the exact moment when the sun crosses the celestial meridian over a location, which means it is at its highest point in the sky.
Today, noon refers to the midpoint between sunrise and sunset or the time when the sun reaches its peak position in the sky. In simple terms, it is the moment when the sun is at its highest point in the sky, and shadows are the shortest. The exact timing of noon varies from location to location depending on the geographic location and the time of the year.
Noon is called noon because it comes from the Latin term for the ninth hour of daylight, and it has evolved over the years to refer to the moment when the sun is at its highest point in the sky, which is usually around 12 noon on a 12-hour clock system.
Why does 12 am come before 1 am?
12 AM comes before 1 AM because of the way that we measure and divide time. Time is divided into 24 hours, with each hour consisting of 60 minutes and each minute consisting of 60 seconds. The 24 hours of a day are divided into two sets of 12 hours each: the first set runs from midnight (12 AM) to noon (12 PM), and the second set runs from noon (12 PM) to midnight (12 AM).
When we count the hours of the day, we start at midnight, which is technically the first hour of the day. So, the hour immediately following midnight is 1 AM. This means that, in the context of our 24-hour day, 12 AM comes before 1 AM simply because it is the first hour of the day.
It is worth noting that the 12-hour clock that we commonly use in the United States and other countries can sometimes create confusion about the order of the hours. This is because the 12-hour clock resets at noon and midnight, so that 12 PM (noon) follows 11 AM, and 12 AM (midnight) follows 11 PM.
However, in the 24-hour clock that is used in many other parts of the world, the order of the hours is always unambiguous, with 12 AM coming before 1 AM, and so on.
Is it correct to say 12 am?
Yes, it is correct to say 12 am, and it refers to the time of midnight. However, this can also be a bit confusing because when we use a 12-hour clock system, the transition from one day to another is noticed when the clock strikes 12 o’clock. The abbreviation “AM” stands for ante meridiem, which is a Latin term for “before noon,” so it is technically incorrect to use it to indicate midnight.
Nevertheless, it is still widely used in many countries as a matter of convention and tradition.
To avoid confusion, some people prefer to use a 24-hour clock system, where time is represented from 00:00 to 23:59, without the need to distinguish between AM or PM. In this system, midnight is represented by 00:00, and any time after midnight up to 11:59 is in the AM portion of the day, while any time after 12:00 is PM.
It is correct to say 12 am in the 12-hour clock system to refer to midnight, even though it can be a bit confusing or technically incorrect. On the other hand, using a 24-hour clock system may provide a clearer and less misleading way of indicating time, especially for those who prefer accuracy or convenience in their timekeeping.
Do 12am and 12pm exist?
The answer to the question whether 12AM and 12PM exist depends on the context being discussed. In the traditional 12-hour clock system, 12PM (midday or noon) and 12AM (midnight) technically do exist, and they both represent specific points in time during the day.
Midday, which is officially designated as 12:00 PM, refers to the time when the sun is at its highest point in the sky. Similarly, midnight, represented as 12:00 AM, is the time when it is darkest and the sun is on the opposite side of the earth.
It’s, however, worth noting that the 12-hour clock system can be confusing since it can be challenging to distinguish between times that are close to midnight or midday. To alleviate this confusion, the 24-hour clock system, also known as the military time, clearly distinguishes between the two times.
In the 24-hour clock system, midnight is represented as 00:00, and midday is denoted as 12:00.
It’s important to note that in some countries, such as the UK, the 12-hour clock system is commonly used, while others, like the US and Canada, use the 12-hour clock system alongside the 24-hour clock system.
While the 12-hour clock system can be ambiguous, 12AM and 12PM exist, and they both represent two specific times during the day – midnight and midday – although the use of the 24-hour clock system offers less confusion and more precision in terms of differentiating the two times.
Why does AM and PM change at 12 and not 1?
AM and PM are used to indicate the different halves of a day in the 12-hour clock system. AM stands for “ante meridiem” which means “before midday,” while PM stands for “post meridiem” which means “after midday.” The reason why AM and PM change at 12 and not 1 is because 12 o’clock can be either noon or midnight depending on the context.
When the clock strikes 12 noon, it is the exact midpoint of the day, and it is neither morning nor afternoon. Therefore, it makes sense for the time to change from AM to PM at this point. Similarly, when the clock strikes 12 midnight, it marks the end of one day and the beginning of the next. Again, it makes sense for the time to change from PM to AM at this point, marking the start of a new day.
If the time were to change from AM to PM at 1 o’clock, it would not accurately reflect the midpoint of the day, and it would cause confusion when referencing times in the morning or afternoon. For example, if someone were to say that an event starts at 1 PM, it could be interpreted as either 1 hour past noon or 1 hour past midnight, depending on the context.
By keeping the change at precisely 12 o’clock, it avoids this confusion and provides clarity in communication.
Am and PM change at 12 o’clock because it is the exact midpoint of the day, and it marks the transition from one day to the next. Changing the time at 1 o’clock would cause confusion and lack clarity in communication.
Does 1am come after 12 AM?
Yes, 1 am comes after 12 am. To understand this better, we need to understand the concept of time keeping and the twelve-hour clock system. The twelve-hour clock system is a timekeeping method that divides the day into two 12-hour cycles – the period from midnight to noon, known as AM (Ante Meridiem), and the period from noon to midnight, known as PM (Post Meridiem).
The clock uses the figures 1 to 12 twice in the day. So, 12 am is the start of the first 12-hour cycle, and it marks the beginning of a new day at midnight. The time after 12 am is still considered the same day that began at midnight. As the clock progresses, each hour is numbered sequentially from 1 to 12, and this numbering system repeats every 12 hours.
Therefore, when the clock strikes 1 am, it means that one hour has elapsed after 12 am, indicating that the first hour of the new day has begun. So, 1 am comes after 12 am and is a part of the AM cycle. In contrast, if the clock were to strike 1 pm, it would mean that it’s one hour past noon, and the PM cycle has begun.
The 12-hour clock system divides a day into two 12-hour cycles, starting at midnight and noon, respectively, with numbers 1 to 12 applied twice in a day. When the clock hits 1 am, it marks the beginning of the new day after 12 am, indicating that an hour has passed in the AM cycle. Therefore, 1 am undoubtedly comes after 12 am.
Is 12 AM before 1pm?
No, 12 AM is not before 1 PM. The 12-hour clock system divides the day into two periods, namely AM (Ante Meridiem) and PM (Post Meridiem). AM refers to the time before noon, and PM refers to the time after noon. The system starts counting from midnight, which is denoted as 12 AM, and ends at noon, which is denoted as 12 PM.
Therefore, 12 AM is the exact moment when the day starts, and it is followed by the hours 1 AM, 2 AM, and so on until noon, which is 12 PM. After noon, the hours are denoted as 1 PM, 2 PM, and so on until midnight, which is 12 AM again.
12 AM is the first hour of the day and occurs at midnight, while 1 PM is in the afternoon and occurs after noon, which means that 12 AM is not before 1 PM.
Why is 12 AM considered morning?
The reason why 12 AM is considered morning is due to the way time is structured in the 24 hour format. The 24 hour format is used to divide the day into 24 equal parts of one hour each where the day starts at 12 AM or mid night and ends at 11:59 PM or just before midnight. In this format, each hour of the day is numbered from 0 to 23 hours with 12 AM representing both the start of the day and the start of the hour cycle.
The word “AM” stands for “ante meridiem” in Latin, meaning “before mid-day”. Similarly, “PM” stands for “post meridiem”, meaning “after mid-day”. Hence, 12 AM represents the first hour after midnight, which is technically before mid-day, and hence considered as morning.
Further, the concept of dividing the day into two parts, morning and afternoon/evening, is a common practice globally, regardless of the time format used. In the 12 hour format commonly used in the United States, 12 AM is still considered the start of the morning, and the time between 12 AM and 11:59 AM is still considered morning.
12 AM is considered morning since it is the first hour of the day in the 24 hour format and is technically before mid-day. The time format and the global practice of dividing the day into morning and afternoon/evening also contribute to this consideration.
Why is it called noon and not midday?
Noon is defined as the time of day when the sun is at its highest point in the sky, which typically occurs around 12 p.m. in most parts of the world. The term noon comes from the Latin word ‘nona’ which means ninth hour, as it was deemed the ninth hour of daylight, with daylight being divided into twelve hours between sunrise and sunset.
On the other hand, midday is simply defined as the middle of the day, or the point halfway between sunrise and sunset. While the two terms may seem interchangeable, they actually have slightly different meanings and origins.
Historically, midday was a more general term used to refer to any time in the middle of the day, whereas noon referred specifically to the time when the sun was highest in the sky. In modern times, however, the term midday has fallen out of common usage in favor of the more precise term noon.
Furthermore, the term noon has been used for centuries in various cultures and languages to refer to the middle of the day when the sun is highest in the sky. It has become a common and accepted term in many parts of the world, whereas midday is often seen as more informal and colloquial.
While the terms noon and midday may have similar meanings, the term noon has become the more widely accepted and precise term for the point in the day when the sun is at its highest point in the sky. Its Latin roots and centuries-old usage have contributed to its popularity and recognition across different regions and cultures.
How did 12 PM become noon?
The term ‘noon’ entered the English language during the 14th century and was derived from the Latin word ‘nona’, which referred to the ninth hour of the day. This was because Roman timekeeping systems divided daylight hours into twelve hours, which started at sunrise and ended at sunset. Consequently, the ninth hour of the day, which was around 3 PM, was referred to as ‘nona’.
However, during the Middle Ages, mechanical clocks began to grow in popularity, and the hours on these mechanical clocks were numbered from one to twelve. This meant that the ninth hour of the day, which was previously called ‘nona’, became the twelfth hour on these mechanical clocks. Thus, the time of day that was formerly called ‘nona’ was now referred to as ‘midday’ or ‘noon’.
Over time, the meaning of the term ‘noon’ evolved, until it became the universally accepted term for the time of day precisely halfway between sunrise and sunset. In modern times, the term ‘noon’ is used interchangeably with ‘midday’ to refer to the time of day when the sun is at its highest point in the sky, and most people take their lunch break or pause for a midday meal.
The term ‘noon’ emerged as a result of the development of mechanical clocks during the Middle Ages, which led to a shift in the way that hours were numbered, and the ninth hour of the day came to be known as the twelfth hour. Through the centuries, the meaning of ‘noon’ evolved until it became the widely recognized term for the time of day halfway between sunrise and sunset, and an integral part of everyday life.
Is 12 noon called pm?
No, 12 noon is not called PM. PM stands for “post meridiem” which means “after midday” in Latin. It is used to refer to the period of time between noon and midnight. On the other hand, 12 noon is exactly halfway between midnight and midnight the following day, hence, it is neither after nor before midday.
It is simply referred to as “noon” or “12:00 PM” for convenience in modern timekeeping.
However, it’s important to note that some cultures may use different timekeeping systems, and as such may refer to noon as something else entirely. For example, in the Jewish tradition, noon is known as “chatzot” and is considered an important time for prayer and reflection. Similarly, in some Islamic cultures, noon is called “Dhuhr” and is one of the five daily prayers observed by Muslims.
The term “PM” is not used to refer to 12 noon. It is an acronym that specifically denotes the time period between noon and midnight. While different cultures may have unique ways of referring to noon, in contemporary Western society, it is simply known as “noon” or “12:00 PM”.
Who invented noon?
The concept of noon is not something that has been invented by a single person, but rather it is a natural occurrence that has been observed and utilized by humans for thousands of years. Noon is traditionally defined as the point in time when the sun is at its highest point in the sky, and it occurs midway between sunrise and sunset.
Historically, the concept of noon has been used to measure time and to determine the length of the day. Early civilizations such as the Babylonians, Egyptians, and Greeks all used the movement of the sun to measure time, and noon was a crucial part of their understanding of the solar cycle.
One of the earliest devices for measuring noon was the sundial, which was used by civilizations such as the Egyptians and Greeks to track the movement of the sun across the sky. The sundial worked by casting a shadow onto a marked surface, and the position of the shadow indicated the time of day. Later, more sophisticated sundials were created, which were capable of tracking the seasonal changes in the sun’s path.
As time progressed, new technologies were developed for measuring time, such as water clocks and mechanical clocks. These devices were able to measure time more accurately than the sundial, and they allowed for the development of more precise calendars and schedules.
Today, noon is still a critical concept in modern society, and it is used as a reference point for many different aspects of our lives. From business meetings to school schedules, the time of day is often defined and organized around the concept of noon.
While no single person can be credited with inventing noon, the concept has been critical to human understanding of time and has been utilized by civilizations throughout history. Today, the importance of noon continues to shape our daily lives and our understanding of the world around us.
How is the time from 12 midnight to 12 noon?
The time from 12 midnight to 12 noon is typically referred to as the morning hours. This time period is usually associated with the beginning of a new day and is characterized by a gradual increase in daylight as the sun rises in the sky.
Most people are asleep during the early hours of the morning and wake up to begin their daily routine at around 6 am to 8 am. This is a time when people start getting ready for work, school or any other activities that they have planned for the day.
The atmosphere during this time of the day is noticeably different from the late night hours. The morning air is usually fresh and cool, and the surroundings are calm and serene. There is generally less traffic on the roads, and the streets are relatively quiet.
The energy during the morning hours is generally high, and people tend to be more alert and focused compared to the late-night hours. Many people find it easier to focus on tasks during this time of the day and are often at their most productive.
Additionally, the morning hours are a great time for physical activities such as jogging, cycling, yoga, or even a simple walk. This is a time when the weather is usually pleasant, and the surroundings are peaceful, making it an ideal time for outdoor activities.
The time period from 12 midnight to 12 noon is a crucial part of the day. It marks the beginning of a new day, and the energy and atmosphere of the morning can set the tone for the rest of the day. It is a time of the day that people should make the most of by engaging in healthy activities and getting their day started on the right foot.
