The four seasons.The four seasons are spring, summer, fall (autumn) and winter.Â©bigstockphoto.com/iluzia. Earth spins around the Sun at an angle, which is why we have different seasons. Most modern day calendars around the world reflect this and divide the year into 4 seasons: spring, summer, fall (autumn), and winter. The dates of when these seasons begin and end, vary depending on who you ask.
The astronomical spring begins on 20 March 2017 and ends on 20 June 2017. The astronomical calendar determines the seasons due to the 23.5 degree tilt of the Earth's rotational axis in relation to its orbit around the sun. Both equinoxes and solstices are related to the Earth's orbit around the sun.
