The seasons have no official dates that carry any legal sanction like the days, months, and years that are the official calendar based units of time. Calendar based dates used by the World Meteorological organization to mark the climatological change of seasons (March 1, June 1, September 1, and December 1) are conventional for the meteorological profession but have limited application outside meteorology. Dates used by the International Astronomical Union using the solstices and equinoxes to define their four season model have been picked up and strongly promoted by the mass media and calendar makers for public comsumption. In fact, the conventional astronomical reckoning has no more official status than any other method of determining seasonal change. Many ecologists use a six season model that uses not the calendar, but changes in animal and plant activity to define seasonal changes. The dates that define the hibernal (winter), prevernal (pre-spring thaw), vernal (spring growing season), estival (high summer), serotinal (late summer), and autumnal (fall) seasons are not fixed on the calendar because they vary from one climate region to another and can fluctuate from one year to the next. Obviously no "official" dates can be applied here either. In conclusion, dating seasonal changes are matters of meteorological, astronomical, and ecological conventions which all differ from each other and are not the product of official laws or regulations.

Why do seasons repeat year after year?
Seasons repeat year after year due to the Earth's axial tilt as it orbits the Sun. This tilt causes different parts of the Earth to receive varying amounts of sunlight at different times of the year, resulting in the changes in seasons. As the Earth completes its orbit around the Sun, the axial tilt ensures that the same seasonal patterns occur annually.

How are the seasons created and what factors contribute to their changing patterns throughout the year?
The seasons are created by the tilt of the Earth's axis as it orbits the sun. This tilt causes different parts of the Earth to receive varying amounts of sunlight throughout the year, leading to the changing patterns of the seasons. Factors such as the Earth's orbit, axial tilt, and distance from the sun all contribute to the changing patterns of the seasons.
How many Seasons in the year?
Astronomical seasons are spring, summer, autumn, winter. Ecological seasons are prevernal (pre-spring thaw), vernal (spring growing season), estival (high summer), serotinal (late summer), autumnal (fall), and hibernal (winter).
What do seasons depend on?
Seasons depend on the tilt of the Earth's axis as it orbits the Sun. The angle of the Sun's rays hitting the Earth's surface changes throughout the year, causing different parts of the Earth to receive more or less sunlight, resulting in seasons.
