Vernal equinox (about March 21): day and night of equal length, marking the start of spring. Summer solstice (June 20 or 21): longest day of the year, marking the start of summer. Autumnal equinox (about September 23): day and night of equal length, marking the start of autumn.
What Is the Equinox? And What Is the Solstice? By Graham Jones. Equinoxes and solstices are a result of two things: Earth’s tilt and its orbit around the Sun.
The seasons (with the transition points of the June solstice, September equinox, December solstice, and March equinox) and Earth's orbit characteristics. For an observer at the North Pole, the Sun reaches the highest position in the sky once a year in June. The day this occurs is called the June solstice day.
Mar 2, 2024 · The astronomical phenomenon of solstice and equinox are familiar to most. But what do they mean, what are events related to them, and how do they influence the seasons on Earth- these are some of the in-depth questions that will be answered here. Read further to learn more. Equinoxes and solstices are radically opposing.

Far left: June solstice. The equinoxes are the only times when the solar terminator (the "edge" between night and day) is perpendicular to the equator. As a result, the northern and southern hemispheres are equally illuminated.
Dec 21, 2023 · What is the difference between an equinox and a solstice? When the equinox occurs, as the equi-prefix might suggest, day and night are of equal length, and it marks the onset of spring (vernal equinox) and autumn (autumnal equinox).

Oct 19, 2023 · This is the December solstice. As its name suggests, an equinox indicates equally illuminated hemispheres, with the solar terminator equally dividing Earth from north to south. (The solar terminator is the shadowed line indicating daylight and sunlight on a globe.) A true equinox would indicate 12 hours of both day and night.
