The exact timing of the equinoxes changes from year to year, but in 2025, the northern hemisphere's Vernal (Spring) Equinox and the southern hemisphere's Autumnal (Fall) Equinox, occur on March 20, at 9:01 UTC or 5:01 a.m. EDT. DON'T MISS: What's the differ...
Precession of the equinoxes, motion of the equinoxes along the ecliptic (the plane of Earth’s orbit) caused by the cyclic precession of Earth’s axis of rotation. The precession is a cyclic wobbling of Earth’s axis with a period of 25,772 years. Learn
During anequinox, the Suncrosses what we call the “celestial equator”—an imaginary extension of Earth’s equator line into space. The equinox occurs precisely when the Sun’s center passes through this line. For those in the Northern Hemisphere, when the Sun crosses the equator going from ...
Precession of equinoxes - calendar makingJust like the axis of a rotating top, the axis of the Earth moves in a conical path about the ecliptic pole and completes it in about 25800 years. This motion of the Earth is known as precession. Due to this precessional motion, the equinoctial ...

What defines each season? Below is a brief explanation of the four seasons in order of calendar year. For more information, refer to the link of the equinoxes and solstices pages. Spring On the first day of spring, the length of day and night is about the same, lasting around 12 hours...
The meaning of PRECESSION OF THE EQUINOXES is a slow westward motion of the equinoxes along the ecliptic caused by the gravitational action of sun and moon upon the protuberant matter about the earth's equator.
The Master invokes the Augoeides; the pupil through sympathy is almost rapt away. The Augoeides hath given the Master a message; namely, to manifest the New Way of the Equinox of Horus, as revealed in Liber Legis. He does so, and reconciles it with the Old Way by inviting the ...
Equinoxes and Solstices on Other Planets Everyplanetin thesolar system, apart fromMercury, is tilted on its axis of rotation. This means each planet has its own equinoxes and solstices. VenusandJupiterhave small axial tilts of 2.6* and 3.1 degrees, respectively. Venus orbits the Sun more qu...
precession of the equinoxes n. A slow westward shift of the equinoxes along the plane of the ecliptic, resulting from precession of the earth's axis of rotation, and causing the equinoxes to occur earlier each sidereal year. The precession of the equinoxes occurs at a rate of 50.27 second...
