Year (Tropical) as a Unit of Time
A tropical year, also known as a solar year, is the time it takes for the Earth to complete one full orbit around the Sun, measured from one vernal equinox to the next. This duration is approximately 365.2422 days, which is the basis for the calendar year most commonly used today. The tropical year is crucial for understanding the changing seasons, as it aligns with the Earth's axial tilt and its relation to the Sun's position.
To account for the fractional day in the tropical year, the Gregorian calendar incorporates leap years, adding an extra day every four years, with exceptions every century unless the year is divisible by 400. This careful adjustment ensures that our calendars remain synchronized with the seasons over long periods, reflecting the natural cycles that govern agricultural and ecological processes.
