At seasons are the periods in which the year is divided according to its climatic characteristics.
They exist four seasons: spring, summer, autumn and Winter. They occur over a period of one year.

O translation movement and the differences in the Earth's inclination relative to the Sun determine the seasons of the year.
While the equinox marks the beginning of autumn and spring, the solstice marks the beginning of summer and winter.
