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.

What are some dates of the event of an solstice and an equinox?
The solstices are generally on June 21 and December 21; the equinoxes are usually on March 21 and September 21. These dates can vary a day or two either way, depending on the cycle of leap years. The U.S. Naval Observatory publishes a web page called "Earth's Seasons" which lists the dates and times of the solstices and equinoxes for each year, down to the minute. See the link below.
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.
When do the the equinoxes occur?
On Earth, the equinoxes occur around March 21 and September 21, but these dates can vary a day or so either way depending on the cycle of leap years. The US Naval Observatory's "Earth's Seasons" web page can show you the precise time of the equinox each year.
When does the annual equinox occur in the southern hemisphere?
At the same time as in the Northern Hemisphere The equinoxes are around March 21 and September 22 each year (the calender date shift slightly due to the uneven number of days in a year - that's why we have leap years almost every fourth year- to bring the equinox es and solstices back to the same calender date).
Are days and nights the same length?
At the "equinox"; "equi-" from "equal", and "nox" from the Latin word for "night". The equinoxes are generally on March 21 and September 21 each year, plus or minus one day because of the cycle of leap years. The US Naval Observatory has a web site for "Earth's Seasons" at which you can see the precise times of the solstices and equinoxes.
In which months do equinoxes take place?
September 22-23 & March 21-22. They mark the beginnings of autumn and spring respectively, in the northern hemisphere. They mark the beginnings of spring and autumn, respectively, in the southern hemisphere.The Spring equinox and the Autumnal equinox occur when the length of daytime and the length of nighttime are exactly equal to each other.
How many days in summer leap year?
As the extra day is in February, it does not affect the amount of days in summer in a leap year. As to how many days there are, well that depends on different interpretations of when exactly summer is. Some people assign it to different months, while others base it on the equinoxes and solstices. In the northern hemisphere some would say it is May, June and July, others that it is June, July and August, and others that it is from the 21st of June to the 20th of September. Those are different again in the southern hemisphere. For there, you would also have different interpretations of when summer is, and in that instance, the month of February could be included, in which case there would be an extra day.
Does the date of the equinox vary?
Any calendar is a man-made idea; so is the idea of "date". There are a number of calendars commonly used throughout the world, and unless the calendar is adjusted to FORCE the vernal equinox to occur on a certain date, then yes, the "date" of the vernal equinox will vary.
What is the approximate date for each year for vernal equinox?
In the northern hemisphere, it is about March 21, and in the Southern Hemisphere, the vernal (spring) equinox is about September 21. Those dates can fluctuate a day or two either way depending on the cycle of leap years. You can look up the precise time of the equinoxes and solstices on the U.S. Naval Observatory's web site "Earth's Seasons" at the link below.
How many leap years occur in 50 years?
As least 11 but no more than 13 leap years occur in 50 years.
What time on septenber 21 does summer end?
We think of the equinoxes as always occurring on March 21 and September 21, but this can vary a day or two either way depending on the cycle of leap years. This year, in 2010, the northern hemisphere end of summer occurs on September 23, 2010. at 03:09 Greenwich Mean Time. If you live in North America, summer ends for you late in the evening of September 22, depending on your time zone. The U.S. Naval Observatory lists the dates and times for the solstices and equinoxes on their "Earth's Seasons" web page at the link below.
WHEN IS THE OLYMPIC NOT A LEAP YEAR?
The winter Olympics are never held during a leap year, they occur mostly in February of even-numbered non leap years. The summer Olympics occur in leap years (most of the time), with the exception of century years like 1900 and 2100, which are not leap years.
