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.

∙ 11y agoThere are two solstices the Summer solstice and the Winter solstice. The other two are the Vernal (Spring) Equinox and the Autumnal (Fall) Equinox. The solstices mark the two days when the days are longest in terms of sun light (Summer Solstice) and the shortest in terms of sun light (Winter Solstice) and the Equinoxes are when the day and night last for the same amount of time.

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.

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 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.
