Because the Earth is going around the sun every 365-366 days. The equinoxes create the seasons such as spring, summer, fall, and winter. Each equinox is a place on the circle of the Earths path.

Why are the equinoxes special times during the year?
The year has two equinoxes, which are the days on which the night and day are of equal length.

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.
