Year (Tropical)
A year (tropical) is the period of approximately 365.24 days, representing one cycle of the Earth's seasons based on the vernal equinox.
History/Origin
The tropical year has been used since ancient times to track seasons and calendar systems, with the Gregorian calendar refining the measurement to align with the Earth's orbit around the Sun.
Current Use
The tropical year is used as the basis for the Gregorian calendar, which is the most widely adopted civil calendar worldwide, to organize years and seasons.
Second (Sidereal)
A second (sidereal) is the time measurement based on Earth's rotation relative to distant stars, approximately 3 minutes shorter than the solar second, used in astronomy.
History/Origin
The sidereal second has origins in astronomical observations of Earth's rotation relative to distant celestial objects. It was established to provide a precise time standard for celestial measurements, differing from the solar second used in everyday timekeeping.
Current Use
The sidereal second is primarily used in astronomy and astrophysics for precise time measurements related to celestial events, star tracking, and satellite navigation systems.
