Introduction
Have you ever wondered how the 365 days calendar we use today came into existence? Who invented it, and what was the reason behind it? In this article, we will discuss the history and origin of the 365 days calendar.
The Origin of the Calendar
The origin of the calendar can be traced back to the ancient times when humans used to follow the lunar calendar, i.e., the calendar based on the phases of the moon. The lunar calendar was used by many civilizations, including the Egyptians, Babylonians, and Greeks. However, the lunar calendar had some limitations. It was not accurate, and it did not correlate with the seasons.
As a result, the Egyptians came up with a new calendar based on the solar calendar. They divided the year into 12 months, each consisting of 30 days, and added five days at the end of the year. This calendar was known as the "civil calendar."
The Roman Calendar
The Romans also had their own calendar, which was a lunar calendar. However, it was not accurate, and they faced many problems with it. As a result, they decided to adopt the Egyptian calendar and added two months, January and February, to it. The Roman calendar was a 355 days calendar, and every two years, they added an extra month to align it with the seasons.
Julian Calendar
Despite the changes made to the calendar, it was still not accurate. In 45 BCE, Julius Caesar consulted with the Egyptian astronomer Sosigenes and came up with a new calendar, known as the Julian calendar. The Julian calendar was a 365 days calendar, with a leap year added every four years to account for the extra quarter of a day in the solar year.
Question: Who invented the 365 days calendar?
Julius Caesar, in consultation with Sosigenes, invented the 365 days calendar.
The Gregorian Calendar
Despite the accuracy of the Julian calendar, it was still not perfect. The extra quarter of a day in the solar year was not accounted for adequately, and over time, the calendar fell out of sync with the seasons. In 1582, Pope Gregory XIII introduced a new calendar, known as the Gregorian calendar. The Gregorian calendar was a modified version of the Julian calendar, with a leap year occurring every four years except for years that are divisible by 100 but not by 400.
Question: Who introduced the Gregorian calendar?
Pope Gregory XIII introduced the Gregorian calendar.
Conclusion
In conclusion, the 365 days calendar we use today has been developed over many centuries, with contributions from various civilizations and people. The Egyptians, Romans, Julius Caesar, and Pope Gregory XIII all played a significant role in the development of the calendar. Today, we take the 365 days calendar for granted, but it is essential for our daily lives and helps us keep track of time and seasons.
