A tropical year or solar year (or tropical period) is the time that the Sun takes to return to the same position in the sky – as viewed from the Earth or another celestial body of the Solar System – thus completing a full cycle of astronomical seasons.
It is also in this frame of reference that the tropical year (or solar year), the year related to Earth's seasons, represents one orbit of Earth around the Sun. The precise definition of a sidereal day is the time taken for one rotation of Earth in this precessing frame of reference.

The wet season, rainy season or green season is the time of year, ranging from one or more months when most of the average annual rainfall in a region falls. [9]
Per tropical calculations, in contrast, persons born between March 21 – April 19 would have the sun sign of Aries. [11] Precession of equinoxes, the changing position of the vernal equinox over the course of about 25,800 years. The yellow line is a section of the ecliptic, the apparent path the Sun appears to follow over the course of an ...
The modern definition of mean tropical year differs from the actual time between passages of, e.g., the northward equinox, by a minute or two, for several reasons explained below. Because of the Earth's axial precession , this year is about 20 minutes shorter than the sidereal year.
Tropical climate is the first of the five major climate groups in the Köppen climate classification identified with the letter A.Tropical climates are defined by a monthly average temperature of 18 °C (64 °F) or higher in the coolest month, featuring hot temperatures and high humidity all year-round.
A pair of siblings have reignited a debate over cake — specifically, what it means to be a chocolate cake. In December, Gia Cooper posted a video to TikTok, and later to Instagram, where the ...
The sidereal year is 20 min 24.5 s longer than the mean tropical year at J2000.0 (365.242 190 402 ephemeris days). [1] At present, the rate of axial precession corresponds to a period of 25,772 years, [3] so sidereal year is longer than tropical year by 1,224.5 seconds (20 min 24.5 s, ~365.24219*86400/25772).
