The Solstices' are the longest day [June 21 or 22(in northern hemisphere)] and Shortest day in [December 21 or 22(northern hemisphere)]. The Equinoxes happen every 6 months in September 21st and March 21st, they're also another word for Daylight Savings Time.
Solstices occur when the sun reaches the highest and lowest points in the sky. The summer solstice is on the 21st June and the winter solstice is on the 21st December.
Equinoxes are different, they occur around 20th March and 22nd September, when the Earth is neither pointing towards the sun or away from it. They are roughly between the solstices. At an equinox, day and night will be roughly the same duration.
The axis of rotation round which the earth spins (a line passing through the middle of the Earth and the North and South poles) is not upright in relation to the plane described by the Earth as it orbits the Sun. The axis is tilted some 23.5 degrees of the vertical.
This means at one part of the orbit the north pole is pointing towards the Sun and 180 degrees round the orbit, it is pointing away form the Sun.
For the northern hemisphere, winter solstice is when the Sun is furthest to the South, summer solstice is when the Sun is furtherst to the North. For the Southern Hemisphere, it is the other way round.
The solstices and equinoxes are points on the map of the stars. Regardless of
where you live, the sun reaches and passes those points at the same times ...
the equinoxes on March 21 and near September 22, and the solstices near June 21
and December 22.
The thing that does depend on your hemisphere is the seasons that begin for you
on each of these dates.
March Equinox:
Northern . . . Spring begins
Southern . . . Fall begins
June Solstice:
Northern . . . Summer
Southern . . . Winter
September Equinox:
Northern . . . Fall
Southern . . . Spring
December Solstice:
Northern . . . Winter
Southern . . . Summer
During the Earth's movement around the Sun, the axis tilt. Four times a year this causes the solstice and equinoxes. These are also called our seasons. Spring, Summer, Fall, and Winter.

Equinoxes are when there are twelve hours of daylight and 12 hours of darkness. The autumnal equinox is on September 21st on average, and the vernal equinox is on March 21st on average. You can tell that the seasons have changed and the equinoxes and solstices have occured because the amount of sunlight changes and temperatures also change. Solstices are when there is either the shortest or longest amount of daylight. The summer solstice is when there is the longest amount of daylight. After the summer solstice, days begin to slowly get shorter until the autumnal equinox. The winter solstice is when there is the shortest amount of daylight. After the winter solstice the days get longer until you reach the vernal equinox.
This is not a short answer question. I will provide the equinox and the solstice article below so you can get your answer straight in the related links box below.
The two equinoxes occur every spring and autumn. The "equinoxes" are two points on the map of the stars. The center of the sun reaches and passes one of them at some moment around March 21, and the other one at some moment around September 22. At those moments, the sun is directly overhead some point on the earth's equator, and every place on earth has roughly equal periods of sun-up and sun-down on that day ... the only two times in the year when these things happen.
On the equinoxes day and night are of equal duration. On the solstices the difference between day and night are their maximum (longest day for summer solstice ... shortest day for winter).
The equinoxes and solstices are the first days of seasons. On the equinoxes, night and day is the same length. On the solstices, the day is either the longest or the shortest day of the year, depending on which solstice it is and which hemisphere you are in,
No, the solstices and equinoxes mark the beginnings of the four seasons.
Yes. If we did not insert the leap day during leap year, the calendar date of the equinoxes and solstices would change and eventually come at very different times in the calendar year. The whole purpose of Leap Year/Leap Day is to keep our calendar aligned with the equinoxes, solstices, and seasons in general.
Yes, the date of each of the equinoxes and each of the solstices varies from year to year due to the differences between a calendar year (365 or 366 days) and an average actual year (about 365.24219878 days). The dates of the solstices and equinoxes also vary depending on where you are on earth, since there are always at least two days in progress on earth at any given time.
A lot of things. equinoxes, solstices, (as a few) you need to elaborate more :)
The solstices are generally on June 21 and December 21 each year, but these dates can vary a day either way depending on the cycle of leap years. You can see the precise time of the solstices and equinoxes each year on the U.S. Naval Observatory's web page "Earth's Seasons", at the link below.
The two equinoxes.
equinoxes
Two equinoxes (from the word 'equal') occur each year: one in the Spring, called the vernal equinox from a word for green-ness, and also the autumnal equinox in the Fall. On the day and hour of the equinoxes, days and nights are the same length of time.
The Earth's tilt results in the solstices and euinoxes, depending on where the Earth is in it's orbit around the sun.
91 and a fraction days. The dividing points are the two solstices and two equinoxes. You can see the precise dates of the equinoxes and solstices on the "Earth's Seasons" web site at the US Naval Observatory, at the link below.
