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.

∙ 9y agoThe year has two equinoxes, which are the days on which the night and day are of equal length. They happen when the apparent position of the Sun (on the ecliptic) crosses the Earth's equator.
The equinoxes are usually March 21 and September 22, and on those days the Sun has a declination of zero and is overhead at the equator.

If earth's axis were tilted 45 degrees at what latitudes would the sun be directly overhead on the solstices and the equinoxes?
north and south
Why the dates of the solstices and equinoxes vary?
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.
What are Similarities of summer solstice and winter solstice?

When are the solstices and equinoxes each year?
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.
What are the two equinoxes?
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.
The equinoxes and solstices mark the midpoints of the three seasons?
No, the solstices and equinoxes mark the beginnings of the four seasons.
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,
What occurs between the two solstices?
The two equinoxes.
What occurs midway between the dates of the summer and winter solstices?

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.
How does the revolution of the Earth correlate to the solstices and the equinoxes?
The Earth's tilt results in the solstices and euinoxes, depending on where the Earth is in it's orbit around the sun.
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.
