Details In the field of Time, a unit "c" (century) in the Gregorian calendar is equal to 100 years. The Gregorian calendar, introduced by Pope Gregory XIII in 1582, is the most widely used calendar system in the world today. It is a solar calendar based on a 365-day year divided into 12 months, with a leap year occurring every four years (except for years divisible by 100 but not 400).

A Gregorian century is a way to express a period of time that spans 100 years, often used to categorize historical events or eras. For example, the 18th century would refer to the time period between 1701 and 1800, while the 21st century refers to the time period between 2001 and 2100.
