If you’re like most people, you probably don’t think about the solstices and equinoxes all that much. But for those of us in the agricultural industry, they’re very important—especially when it comes to planting and harvesting crops. Each year, the Earth moves around the sun at a certain speed. This is called the orbital velocity, or revolution. It’s this speed that affects how long it takes for seasons to come and go. For example, during the summer, the Earth is moving closer to the sun.
This means that days are getting longer and it’s harder for plants to photosynthesize. As a result, we have summertime crops such as tomatoes. At the same time, during winter, the Earth is moving away from the sun. This means that days are getting shorter and it’s easier for plants to photosynthesize. Consequently, we have wintertime crops such as wheat. These two things are called the solstices and equinoxes because they mark points where these things happen in relation to the sun. Just like everything else in life—including our circadian rhythms—these cycles are influenced by our orbit
What is a Solstice?
The two most important days of the year for the sun are the summer solstice and winter solstice. They are also called the “summer” and “winter” solstices, respectively. The summer solstice is on or about June 21st and marks the point at which the sun’s apparent northward travel (from east to west) slows to a stop. The winter solstice is on or about December 21st and marks the point at which the sun’s apparent southward travel (from east to west) slows to a stop.
What is an Equinox?
An equinox is the point in the year when the Earth’s axis of rotation is perpendicular to its orbit around the sun. This makes for equal hours of daylight and darkness all around the world. The two equinoxes are March 21st and September 22nd, but there are also three other equinoxes throughout the year.
Why are they important?
The two most important astronomical events of the year are the summer and winter solstices. The summer solstice is the moment when the sun reaches its highest point in the sky on the northern hemisphere, and the winter solstice is the moment when the sun reaches its lowest point in the sky on the southern hemisphere.
The equinoxes are halfway points between these two events. They happen twice a year, once in spring and once in autumn.
Difference Between Solstices and Equinoxes
The two major events in the year are the summer and winter solstices and the spring and fall equinoxes. The solstices mark the point where the sun’s apparent motion in the sky changes from west to east, while the equinoxes mark points where day and night are of equal length (due to Earth’s orbit around the sun).
While these events happen twice a year, there is more than just a simple difference between them. Here are some key differences:
1) The summer solstice is June 21st and marks the longest day of the year. The winter solstice is December 21st and marks the shortest day of the year.
2) The spring equinox is March 20th and marks the first day of spring. The fall equinox is September 22nd and marks the last day of fall.
3) The summer solstice always occurs when Earth is closest to the sun, while both winter solstice and spring equinox occur when Earth is farthest from the sun.
4) Because autumn happens when Earth is farthest from the sun, days tend to be shorter than in other seasons. Conversely, because winter happens when Earth is closest to the sun, days tend to be longer than in other seasons.
How do we celebrate a Solstice or Equinox?
Different cultures have different ways of celebrating a Solstice or Equinox. For example, in the United States, we usually celebrate the Winter Solstice on December 21st, and the Summer Solstice on June 20th.
In many countries around the world, such as England and Ireland, the two solstices are celebrated with a large feast called a Sabbat. There are also ceremonies associated with each solstice that vary from culture to culture.
Whatever your chosen celebration may be, make sure to enjoy it! These events are important not only because they mark the changing of seasons, but also because they’re opportunities to connect with nature and appreciate all that it has to offer.

Frequently Asked Questions on the difference Between Solstices and Equinoxes
What are the two solstices?
The two solstices are the shortest and longest days of the year. The winter solstice is on December 21st, and the summer solstice is on June 21st.
Why do equinoxes and solstices occur?
The equinoxes and solstices occur because the Earth’s rotational axis is not always pointed directly at the sun. During the year, our planet makes one complete orbit around the sun. The north pole points towards the constellation Ursa Major, while the south pole points towards Crux. This imaginary line called the axle of rotation (or ecliptic) crosses through the center of the sun every year, causing seasons to come and go.
During spring and summer, when the Earth is closest to the sun, sunlight strikes directly on our planet’s south pole. This causes intense heat to rise from below and cause plants to grow quickly. In autumn and winter, when we are farthest from the sun, sunlight hits our planet’s north pole instead. This causes cold temperatures in areas near the poles because it takes longer for sunlight to reach these regions.
Why is it called the solstice?
The solstice is the shortest day of the year and the longest day of the year. The word “solstice” comes from the Latin solstitium, which means “the time of the sun’s winter declination.” The summer solstice is on June 21, and the winter solstice is on December 21. The autumnal equinox is on September 22, and the spring equinox is on March 20.
The terms “solstice” and “equinox” are often used interchangeably, but there is a difference. The difference between the two terms is that an equinox is the point in the year when the sun crosses from one sign of the zodiac to another, while a solstice marks the point in the year when daylight hours peak. For example, June 21st marks the summer solstice, while December 22nd marks winter Solstice. Knowing these important dates will help you understand why certain things happen at these times of year and how they can impact your life.
