Clocks are everywhere; you can find them at your house, at work or school, on computers, and in public places like train stations, bus stops, stores, and libraries. See how many different types of clocks you can find by taking a look around. Why do clocks have 12 hours? Or why is there only 12 number in a clock? The answer is that the Ancient Egyptians ultimately divided the day and night into 12 hours due to the finding of 12 stars that night. The clock is therefore only up to 12 instead of 24 in the 15th and 16th centuries. Only a small number of people and nations utilize the phrase from 13:00 on. Will you personally mention it around 1:00 or 13:00?
Why is there only 12 number in a clock?
For thousands of years, people have been keeping track of time and thinking about it. Sand, water, or the location sun in the sky were utilized as time markers by the earliest timekeepers. We use clocks and watches to tell the time these days. But regardless of how to measure time, it is based on how Earth moves around Sun. The North Pole and the South Pole are imaginary lines around which the Earth revolves or spins. It is daytime when the location where you live faces the Sun and you can see the light of sun; it is nighttime when the location faces the Sun but is dark. One “day” is the length of time it takes for the Earth to complete one full rotation.
But since they are a little bit too long, days are not helpful enough on their own to aid us in keeping track of time. Therefore, we break them into smaller units of time known as hours, minutes, and seconds. The Ancient Egyptians enjoyed counting in multiples of twelve and split the day into two groups of twelve hours: twelve for the day and twelve for the night. As a result, a day is made up of 24 hours. Each hour has a fixed duration of one hour, which can be divided into 60 minutes, each of which can be further divided into 60 seconds.
Why is there only 12 number in a clock? The 12 hours are denoted in a circle on mechanical or analog clocks. The numbers are uniformly spread out in sequence along the circle’s edge, with the number 12 always at the top and the number 6 always at the bottom. The hour and the minutes are displayed by two pointers, known as hands. On a 12-hour clock, we count the hours from one in the morning until noon and then from one in the afternoon until twelve in the morning. We refer to the morning hours as a.m. and after midday as p.m.
On digital clocks, however, we can count a day as having 24 hours. If we do this, the numbers 1 to 12 will represent the morning (or a.m.) hours, and the numbers 13 to 24 will represent the afternoon (or p.m.) hours. Thus, 2 p.m. or the afternoon hour would be 14 o’clock.
What does AM and PM mean?
Latin terminology for the hours of the day, AM and PM, are commonly employed. The abbreviations AM and PM stand for Ante meridiem and Post meridiem, which indicates before noon and afternoon, respectively. The first 12-hour period, from midnight to noon, is referred to as AM, and the second 12-hour period, from midday to midnight, is referred to as PM.
Facts about clocks
- A Colorado institute built a clock that is so precise it won’t advance or recede by a second in 20 million years. This clock is used to keep track of internet time.
- Do you know about the first clock ever? Tower clocks constructed in the region extending from northern Italy to southern Germany between 1270 and 1300 during the Renaissance are regarded to have been the earliest clocks ever made. These clocks kept time by ringing bells; they did not yet have dials or hands.
- A pendulum clock accurate at sea level will lose around 16 seconds per day if relocated to a height of 4000 feet due to variations in the local gravity.
- It was intended for the clock’s hands to move “clockwise” to mimic how a sundial’s shadow would move during the day in the Northern Hemisphere.
- The Salisbury Cathedral Clock in Salisbury, England, is the oldest clock in the world which is still operating. This mechanical clock was originally created in 1386.
- The Great Bell of the clock at the north end of the Palace of Westminster in London is known by the nickname “Big Ben,” which is frequently used to refer to both the clock and the clock tower. 3.2 meters (8 feet) is the length of the hour hand. The minute hand, in contrast, is 4.3 meters (14 feet) long. Similar to a stained-glass window, the clock dials are mounted on an iron frame that is 7 meters (23 feet) in circumference and supports 312 pieces of opal glass (on each side).
