Century

A century is a unit of time equal to 100 years. It is commonly used to refer to a period of 100 years in history, often to describe significant cultural, historical, or societal changes over a long span of time.

Origin:

The word "century" comes from the Latin word "centuria", meaning a group of 100. The concept of dividing time into centuries has roots in the Roman system of organizing time and military units. The idea of measuring time in centuries became more formalized during the Middle Ages, as historians began to structure history into manageable periods for recording and analysis. By the time of the Gregorian calendar, the century became a standard way to refer to a 100-year span, often used to discuss developments in history, such as "the 19th century" or "the 21st century." The century is now a common unit used in various fields like history, economics, and demographics.

Day

A day is a unit of time equal to 24 hours, which is the time it takes for the Earth to complete one full rotation on its axis relative to the Sun. It is commonly used to measure the duration of activities, sleep cycles, work schedules, and other daily occurrences.

Origin:

The concept of the day has its roots in ancient astronomy, particularly in the observation of the Earth's rotation. The division of time into days dates back to early civilizations such as the Babylonians, Egyptians, and Greeks, who divided the day into two parts: daylight and nighttime. The 24-hour day originates from the Egyptians, who divided the daytime into 12 hours based on their use of sundials and the nighttime into 12 hours based on star movements. This 24-hour division was later adopted by other cultures and has remained the standard for modern timekeeping, with the cycle of one full rotation of the Earth defining the length of a day.
