The astronomy event of Aphelion happens two weeks after the June Solstice or around July 4th. However, the actual date of Aphelion changes every year!
The autumnal equinox.
no, the vernal solice i think
The four days that separate the seasons are; March 20th or 21st ~ Vernal Equinox, December 22nd or 23rd~ Winter Solstice, September 22nd or 23rd~ Autumnal Equinox, and June 21st or 22nd~ Summer Solstice.
The winter solstice for the southern hemisphere happens around the 21st of June.
The main events are: 1. Winter solstice - when the earth is tilted towards the sun. 2. Spring equinox - when day and night are equal in length. 3. Summer solstice - when the earth is tilted away from the sun. 4. Autumnal equinox - when day and night are equal in length.

fall equinox partial equinox
Autumn starts on the date of the Autumnal Equinox and winter starts on the day of the Winter Solstice.
The autumnal equinox is not in December. In the northern hemisphere it is in September. In the southern hemisphere it is in March. In December you have the winter solstice in the northern hemisphere and the southern hemisphere has the summer solstice. Equinoxes and Solstices happen on the 21st of their respective months, though occasionally then can be on the 20th or 22nd.
Different places have different definitions for when summer begins and ends. I go by the rule that summer begins at the moment of the summer solstice and ends at the moment of the autumnal equinox. In the northern hemisphere the date of the summer solstice ranges from June 19 to June 23, and the date of the autumnal equinox ranges from September 21 to September 24. In the southern hemisphere the date of the summer solstice ranges from December 20 to December 23, and the date of the autumnal equinox ranges from March 19 to March 22.
no actually its because of the earths 23.5 degree tilt and so one half of the earth( northern hemisphere, southern hemisphere) is either facing away or toward the earth. But in spring and fall neither of the hemispheres are facing the sun. so basically the distance of the sun does not matter for temature because the earths orbit is not eliptical enough to make a difference in tempature.
The solstice is day of the year with the longest period of light (the summer solstice) or the longest period of night (the winter solstice). The vernal equinox (spring) and autumnal equinox (fall) are the two days in the year in which the periods of light and periods of darkness are exactly the same duration.
There is only two equinoxes, Autumnal equinox(fall) starts on Sept. 22 or 23, and Vernal equinox(spring) starts on March 20 or 21.
March and September Equinoxes: the Equator (zero latitude)June Solstice: Tropic of Cancer, 23.5 degrees north latitudeDecember Solstice: Tropic of Capricorn, 23.5 degrees south latitude
