Imagine that on March 1, your train is at 1 o’clock. You woke up early in the morning and started preparing to go to the station. After packing your luggage, you left home at 11 am so that you have enough time to catch the train. By 1 o’clock you start waiting for your train, but you don’t see any name-o-mark of the train. Then you contact the inquiry center at the station and you find out that your train was at 1am last night and not 1am in the day! You cannot call this situation imaginary because thousands of people fall into such a situation and make mistakes. Its root is our clock system (Why 12 clock system in used) means the system used in the clock.

In most places in the world including India, the system of 12 hours (Why clock have 12 numbers) is mainly used. In such a situation, you must have thought that if there are 24 hours in a day, then why there are only 12 numbers in the clock, keeping the full 24 numbers can solve a lot of people’s problems. Between 12 in the day or 12 in the night, people get entangled in such a way that they find it difficult to catch the train-flight. However, many places online now have a 24-hour clock system, so 24 hours are shown on tickets using numbers such as 00, or 16, but a wall clock or hand clock But still there are only 12 digits.

trend started from ancient civilizations
Let us know what is the reason behind doing this. According to the report of Medium website, the reason is related to the ancient civilizations of ancient Mesopotamia and Egypt. These civilizations had divided the day into 2 cycles. The cycle of the day, which was measured by the movement of the sun, and the cycle of the night, which was measured by the movement of the moon. This is the reason that later people created the concept of AM and PM. Egyptians used to keep clock face of 12 hours in their sun dial and water dial. Water dials were special clocks made using water to measure the time after sunset.

12 counting system was used in Egypt
Now the question arises that why only 12 numbers are used, why not 11 or 10. Ancient people found that there are 12 lunar cycles in a year. Apart from this, people of that time used 12 counting systems for counting, but today 10 are used. The reason for this is that we have 10 fingers, so it is easy to count. But earlier people used to count the 12 compartments of the fingers with the thumb, in this case they chose only 12.
