Difference Between Equinox and Solstice

The difference between the transiting equinoxes is given in tabular form below. But before you know the difference, you need to understand the basic concept of the sun and the solar system.

Difference Between Equinox and Solstice

When the earth rotates around the sun along an elliptical path, its inclined axis (tilted 23 degrees about perpendicular to the plane of the earth’s orbit) the sunlight reaches the surface of the earth at different angles, therefore the length of daylight and night are different and not the same everywhere in the world.

Introduction

These are many words that we hear in our daily life at the beginning of each season. On March 20, 2021, we see spring welcomed with the vernal equinox and on December 21, we welcome the winter seasons with the solstice.

What is SolsticeĜŸ

The two solar eclipses we studied earlier in our junior classes occur every year and are on June 21st and December 21st.

On a solar day, which is also in the hemisphere, there is either the highest daylight of the year which is the summer daylight or the lowest daylight of the year which is the winter solstice for any point other than the equator.

That is, we can say that the seasonal movement of the daily path of the sun visible from the earth that stops at the northern or southern border is retrograde.

What is Equinox?

The equator generally passes through the geometric center of the solar disk. All this happens twice every year on March 20 and September 23. In other words, we can say that it is the time when the center of the visible sun is directly above the equator.

The word comes from the Latin aequinoctium which comes from aequus meaning the same as nox which is the genitive noctis or night.

They are not exactly alike but still that is due to the angular shape of the sun caused by wind fluctuations and the rapidly changing time of day length that occurs at higher latitudes around the equator.

In the hemisphere or in the right hemisphere on the contrary. slightly different dates of leap years and different reasons.

Difference Between Equinox and Solstice

Equinox Solstice
Time of the year when the sun is nearest to the equatorial plane giving equal lengths of day and night. Time of the year when the sun is farthest from the equatorial plane resulting in long nights and days.
An equinox occurs at the start of the spring and fall. The solstice occurs during the summer and the winter.
Occurs on March 21 (Vernal equinox) and on September 23 (Autumnal equinox). Occurs on June 21(Summer Solstice) and on Dec 22 (Winter Solstice).
