17 Seasons

A season is a division of the year based on changes in weather, ecology, and the number of daylight hours in a given region. On Earth, seasons are the result of Earth's orbit around the Sun and Earth's axial tilt relative to the ecliptic plane. In temperate and polar regions, the seasons are marked by changes in the intensity of sunlight that reaches the Earth's surface, variations of which may cause animals to undergo hibernation or to migrate, and plants to be dormant. Various cultures define the number and nature of seasons based on regional variations, and as such there are a number of both modern and historical cultures whose number of seasons vary.

The Afghanistan fighting season refers to the cyclical restarting of fighting every spring during the War in Afghanistan due to weather and economic factors. It generally runs from April to October.

The Atlantic hurricane season is the period in a year from June through November when hurricanes usually form in the Atlantic Ocean. Tropical cyclones in the North Atlantic are called hurricanes, tropical storms, or tropical depressions. In addition, there have been several storms over the years that have not been fully tropical and are categorized as subtropical depressions and subtropical storms. Even though subtropical storms and subtropical depressions are not technically as strong as tropical cyclones, the damages can still be devastating.

The Christmas season, also called the holiday season, or the festive season, is an annually recurring period recognized in many Western and other countries that is generally considered to run from late November to early January.

There are a number of deities associated with seasons and personifications of seasons in various mythologies, traditions, and fiction.

The dry season is a yearly period of low rainfall, especially in the tropics. The weather in the tropics is dominated by the tropical rain belt, which moves from the northern to the southern tropics and back over the course of the year.

The fog season is a season of fog that occurs in some places, because of special meteorological and topographical characteristics, after a rainy period. The fog season is usually based in the cooler months.

A season is a division of the year marked by changes in weather, ecology, and the amount of daylight. The growing season is that portion of the year in which local conditions permit normal plant growth. While each plant or crop has a specific growing season that depends on its genetic adaptation, growing seasons can generally be grouped into macro-environmental classes.

The Harmattan is a season in West Africa that occurs between the end of November and the middle of March. It is characterized by the dry and dusty northeasterly trade wind, of the same name, which blows from the Sahara over West Africa into the Gulf of Guinea. The name is related to the word haramata in the Twi language. The temperature is cold in most places, but can also be hot in certain places, depending on local circumstances.

In Greek mythology the Horae or Horai or Hours were the goddesses of the seasons and the natural portions of time.

The liturgical year, also known as the church year or Christian year, as well as the kalendar, consists of the cycle of liturgical seasons in Christian churches that determines when feast days, including celebrations of saints, are to be observed, and which portions of Scripture are to be read either in an annual cycle or in a cycle of several years.

The social season, or season, refers to the traditional annual period in the spring and summer when it is customary for members of the social elite of British society to hold balls, dinner parties and charity events. Until World War I, it was also the appropriate time to be resident in the city rather than in the country in order to attend such events.

In Norse mythology, Sumarr and Vetr are personified seasons. Sumarr and Vetr, personified, are attested in the Poetic Edda, compiled in the 13th century from earlier traditional sources, and the Prose Edda, written in the 13th century by Snorri Sturluson. In both, the two are given genealogies, while in the Prose Edda the two figure into a number of kennings used by various skalds.

A tellurion, is a clock, typically of French or Swiss origin, surmounted by a mechanism that depicts how day, night, and the seasons are caused by the rotation and orientation of Earth on its axis and its orbit around the Sun. The clock normally also displays the age of the Moon and the four-year (perpetual) calendar.

The tropics are the region of Earth surrounding the Equator. They are delimited in latitude by the Tropic of Cancer in the Northern Hemisphere at 23°26′11.2″ (or 23.43645°) N and the Tropic of Capricorn in the Southern Hemisphere at 23°26′11.2″ (or 23.43645°) S; these latitudes correspond to the axial tilt of the Earth. The tropics are also referred to as the tropical zone and the torrid zone. The tropics include everywhere on Earth which is a subsolar point at least once during the solar year. Thus the maximum latitudes of the tropics have the same value positive and negative. Likewise, they approximate, due to the earth not being a perfect sphere, the "angle" of the Earth's axial tilt. The "angle" itself is not perfectly fixed due chiefly to the influence of the moon, but the limits of tropics are a geographic convention, being an averaged form, and the variance is very small.

In Roman mythology, Vertumnus is the god of seasons, change and plant growth, as well as gardens and fruit trees. He could change his form at will; using this power, according to Ovid's Metamorphoses (xiv), he tricked Pomona into talking to him by disguising himself as an old woman and gaining entry to her orchard, then using a narrative warning of the dangers of rejecting a suitor to seduce her. The tale of Vertumnus and Pomona has been called "the first exclusively Latin tale."

The wet season is the time of year when most of a region's average annual rainfall occurs. Generally, the season lasts at least a month. The term green season is also sometimes used as a euphemism by tourist authorities. Areas with wet seasons are dispersed across portions of the tropics and subtropics.
