{ bidder: 'ix', params: { siteId: '555365', size: [160, 600] }}, On Earth, seasons are the result of Earth's orbit around the Sun and Earth's axial tilt relative to the ecliptic plane. Contrary to popular belief, the phenomenon of the seasons – or the periodic change of climate over the months – is not a result of Earth approaching or moving away from the Sun.

These observances are often declared "official" within their respective areas by the local or national media, even when the weather or climate is contradictory. For approximately half of the year (from around March 20 to around September 22), the Northern Hemisphere tips toward the Sun, with the maximum amount occurring on about June 21. { bidder: 'ix', params: { siteId: '195464', size: [160, 600] }}, The effect of axial tilt is observable as the change in day length and altitude of the Sun at solar noon (the Sun's culmination) during the year.

Less common examples include debris flows, waterspouts, and insect plagues.

Ecologically speaking, a season is a period of the year in which only certain types of floral and animal events happen (e.g. On the other hand, people living far to the west (America) whose clocks run behind UTC may experience an equinox as early as March 19.

The magazine is all about the lives of celebrities. The seasons of the year (winter, spring, summer and autumn) are regular changes in the climatic conditions that occur due to the movement of the Earth around the Sun. Over thousands of years, the Earth's axial tilt and orbital eccentricity vary (see Milankovitch cycles).
