Though they tend to be associated with days, both solstices and equinoxes are instances in time, when Earth's tilt, relative to the sun, is exactly toward, away, or in between.
A solstice occurs when the sun reaches its apparent maximum northerly or southerly angle. This is due to the planet's tilt. On Earth, this is when the Earth's axis tilts exactly toward the sun (northern-most, or summer solstice), and again, when the tilt is directly away from the sun (southern-most or winter solstice). Solstice occurs twice each orbit (year), at approximately June 20/21 and approximately on December 21/22.
The solstices are associated with the longest and shortest days of the year.
An equinox refers to the point at which the sun's apparent position is directly overhead at the equator. On Earth, this is when the Earth's axis tilts neither toward nor away from the sun, but at 90 degrees from the sun. Equinox occurs twice each orbit (year), at approximately March 20/21 (spring equinox), and approximately on September 22/23 (autumn equinox).
The Equinoxes are associated with the time of the year when day and night are approximately equal in length: 12 hours.
On all planets (including Earth) equinoxes and solstices occur in quarterly intervals of that planets orbit around its sun.

These happen because the axis of Earths spin in inclined at an angle from the normal of to the plane in which it orbits the Sun.

One can learn about solstices from the following sources: "Wikipedia", "solstices benefits", "Almanac", "physical Geography", to mention a few. One can also get more information by buying solstices books of Amazon or reading Google books.

No, the solstices and equinoxes mark the beginnings of the four seasons.
Depending on the calendar shift, the summer solstice occurs on the 20th or 21st of June and the Winter solstice occurs on the 20th or 21st of December.
The northern hemisphere experiences two solstices: the summer solstice in late June and the winter solstice in late December. These solstices mark the longest and shortest days of the year, respectively.
These are the solstices. They happen in late December and late June. 23.5 degrees occurs in the northern and southern hemispheres.
There are two solstices. they are the summer solstice (first day of summer), and the winter solstices (first day of winter An equinox is when day and night are the same length. like solstices, there are two of them. The Autumn equinox (first day of autumn), and then the spring equinox (first day of spring).
