This calendar, known as the Egyptian civil calendar, did not factor in leap years and was used for administrative purposes.
Another influential civilization in the realm of timekeeping was the ancient Greeks. They developed the concept of the “metonic cycle,” a 19-year period that was based on the cycles of the moon. This cycle helped synchronize lunar and solar calendars, contributing to a more accurate measurement of time.
Similarly, ancient Romans also had their own calendar. They followed a lunar calendar initially, but it was later replaced by the Julian calendar, introduced by Julius Caesar in 45 BCE. The Julian calendar consisted of 365 days, with an extra day added every four years to account for leap years. This calendar played a crucial role in the establishment of the modern concept of a century.
How These Systems Influenced the Concept of a Century
The various ancient calendars and timekeeping systems laid the foundation for the concept of a century. The Egyptians’ use of a 365-day calendar, for example, indirectly influenced the idea that a century consists of 100 years. This notion later became prevalent in different civilizations and cultures, shaping the way people perceive and measure time.
Furthermore, the introduction of the Julian calendar by the ancient Romans also had a significant impact on the concept of a century. By including the leap year system, the Julian calendar refined the measurement of time, aligning it more closely with the Earth’s orbit around the Sun. This accuracy played a pivotal role in defining and calculating the length of a century.

The Gregorian Calendar
Overview of the adoption of the Gregorian calendar
The Gregorian calendar, named after Pope Gregory XIII, was introduced in 1582 as a reform of the Julian calendar. The Julian calendar had inaccuracies in calculating the length of a year, resulting in a discrepancy between the calendar year and the solar year. The Gregorian calendar aimed to rectify this issue and bring the calendar year more in line with the actual time it takes for the Earth to orbit the sun.
The adoption of the Gregorian calendar was a gradual process and varied across different countries. Initially, it was adopted by Catholic countries, including Italy, Spain, and Portugal. The Protestant countries, however, were initially resistant to the reform as it was seen as a Catholic measure. Eventually, they also adopted the Gregorian calendar.
Impact on the length of a century
One of the major changes implemented by the Gregorian calendar was the adjustment in the length of a year. The Julian calendar had defined a year as 365.25 days, which resulted in a slight overestimate of the length of a solar year. The Gregorian calendar corrected this by introducing the concept of leap years, but with certain exceptions.
According to the Gregorian calendar, a year that is divisible by 100 is not a leap year unless it is also divisible by 400. This adjustment ensures that the length of a year is more closely aligned with the actual time it takes for the Earth to complete its orbit around the sun. By making these adjustments, the Gregorian calendar reduced the average length of a year to 365.2425 days, which is a closer approximation to the solar year.
The impact of these adjustments on the length of a century is significant. In the Gregorian calendar system, a century is defined as 100 years. However, due to the exceptions for leap years, the average length of a century is slightly shorter than 100 years. This means that if we calculate the number of days in a century according to the Gregorian calendar, it is approximately 36,525 days.
The adoption of the Gregorian calendar and its adjustments to the length of a year have had a profound impact on the timeline of an epoch. It has provided a more accurate measure of time and has influenced the way we perceive and study historical and cultural events within the context of a century.
