The Solstices (Summer & Winter) The summer solstice occurs when the sun is directly over the Tropic of Cancer, which is located at 23.5° latitude North, and runs through Mexico, the Bahamas, Egypt, Saudi Arabia, India, and southern China. For every place north of the Tropic of Cancer, the sun is at its highest point in the sky and this is the longest day of the year.
A solstice is an event occurring when the Sun appears to reach its most northerly or southerly excursion relative to the celestial equator on the celestial sphere. Two solstices occur annually, around June 21 and December 21. The seasons of the year are determined by reference to both the solstices and the equinoxes.
The northward equinox occurs in March when the sun crosses the equator from south to north, and the southward equinox occurs in September when the sun crosses the equator from north to south. These terms can be used unambiguously for other planets. They are rarely seen, although were first proposed over 100 years ago.
WINTER SOLSTICE: The first day of the Season of Winter. On this day (DECEMBER 22 in the northern hemisphere *) the Sun is farthest south and the length of time between Sunrise and Sunset is the shortest of the year. * In the southern hemisphere, winter and summer solstices are exchanged. Summer: December 22. Winter: June 21.
The biggest difference between the equinox and the solstice is that a solstice is the point during the Earth's orbit around the sun at which the sun is at its greatest distance from the equator, while during an equinox, it's at the closest distance from the equator.
Summer solstice is also the longest day of the year, in terms of daylight, and marks the first day of summer. Autumn Equinox. Autumn equinox, like the spring equinox, is a special day in which night and day are of nearly equal lengths, within minutes of one another. It also marks the beginning of autumn or fall.
June Solstice (Summer Solstice) is on Friday, June 21, 2019 at 8:54 am in Palo Alto. In terms of daylight, this day is 5 hours, 10 minutes longer than on December Solstice. In most locations north of Equator, the longest day of the year is around this date.
The autumnal equinox occurs in September, and in the Northern Hemisphere this date marks the end of Summer and beginning of Autumn when the days will start getting shorter and the nights longer. Find out more about the autumnal equinox.
