Second

The second (s) is the base unit of time in the International System of Units (SI). It is defined as the duration of 9,192,631,770 periods of the radiation corresponding to the transition between two hyperfine levels of the ground state of the cesium-133 atom. This precise definition allows for accurate and consistent measurements of time across various scientific and practical applications.

Origin:

The second has its origins in ancient Babylonian astronomy, where the day was divided into 24 hours, each hour into 60 minutes, and each minute into 60 seconds. The concept of dividing time into smaller units became more standardized over time, particularly in the 17th century, when the development of more accurate clocks led to a need for precise measurements of time. The modern definition, based on the cesium-133 atom, was adopted in 1967 by the International System of Units (SI) to ensure consistency and precision in timekeeping across scientific fields. The second is now universally used as the fundamental unit of time.

Year

A year is a unit of time equal to the duration of one complete orbit of the Earth around the Sun. In the Gregorian calendar, which is the most widely used calendar system, a year consists of 365 days, or 366 days in a leap year (every 4 years), to account for the additional 0.2425 days in the Earth's orbital period.

Origin:

The concept of a year is tied to the Earth's revolution around the Sun, which takes approximately 365.2425 days. Early civilizations, such as the Babylonians and Egyptians, recognized the annual cycle of seasons and developed calendar systems based on the Earth's orbit. The Julian calendar, introduced by Julius Caesar in 45 BCE, divided the year into 12 months and established a leap year every 4 years. However, the Julian year was slightly too long, so the Gregorian calendar, introduced by Pope Gregory XIII in 1582, corrected this by shortening the average year to 365.2425 days, and refined the leap year rule to keep the calendar year in sync with the solar year. This calendar system is now the global standard.
