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.
The solstices occur around June 21st (summer solstice) and December 21st (winter solstice) each year. The equinoxes occur around March 21st (spring equinox) and September 23rd (autumn equinox) each year.
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.

What are the names of the two equinoxes?
The names of the two equinoxes are the vernal (spring) equinox and the autumnal (fall) equinox.
Why the dates of the solstices and equinoxes vary?
The dates of the solstices and equinoxes vary because Earth's orbit around the sun is not a perfect circle, but an ellipse, causing the speed at which Earth moves around the sun to vary. Additionally, gravitational pull from other celestial bodies, such as the moon and planets, can also influence Earth's orbit and the exact timing of these astronomical events.
What are the two equinoxes?
The two equinoxes are the vernal (spring) equinox, which occurs around March 20th, and the autumnal (fall) equinox, which occurs around September 22nd. During these times, the length of day and night are nearly equal all over the world.
When are the solstices and the equinoxes?
The summer solstice occurs around June 21st, marking the longest day of the year in the Northern Hemisphere and the shortest day in the Southern Hemisphere. The winter solstice occurs around December 21st, marking the shortest day in the Northern Hemisphere and the longest day in the Southern Hemisphere. The spring equinox occurs around March 21st and the autumnal equinox around September 23rd, when day and night are almost equal in length worldwide.
If earth's axis were tilted 45 degrees at what latitudes would the sun be directly overhead on the solstices and the equinoxes?
If Earth's axis were tilted 45 degrees, the sun would be directly overhead at latitudes of 45 degrees north on the summer solstice, 45 degrees south on the winter solstice, and would pass through the equator on both equinoxes.
What are the difference between the equinoxes and the solstices?
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,
Does the leap day affect when equinoxes and solstices occur?
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.
The equinoxes and solstices mark the midpoints of the three seasons?
No, the solstices and equinoxes mark the beginnings of the four seasons.
Are there different end dates for spring depending on the year?
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.
What is happening every half year?
A lot of things. equinoxes, solstices, (as a few) you need to elaborate more :)
What are the dates for each solstice?
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.
What occurs between the two solstices?
The two equinoxes.
How does the revolution of the Earth correlate to the solstices and the equinoxes?
The revolution of the Earth around the sun causes the changing seasons and the positions of the solstices and equinoxes. The solstices occur when the Earth's axis is tilted most toward or away from the sun, leading to the longest and shortest days of the year. The equinoxes occur when the tilt is at a right angle to the sun, resulting in day and night being of nearly equal length.
What occurs midway between the dates of the summer and winter solstices?
equinoxes
When are solstices and equinoxes each year?
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.
How long does a season last?
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.
How are the solstices and equinoxes related to the seasons?
" seasons are the manifestation of solsticesand equinoxesand are markers of the seasons
