The equinox is not really when the day and night are equal. We know that "equinox" derives from the Latin: aequinoctium - "aequi" or "equi" + noct (nox) or night or "equal night"... but No, not equal by a few minutes of the day
At the precise moment of the equinox there are three things happening:
1.) the sun is at zenith over the equator
2.) where the sun rises, it does so exactly in the east and where it sets it does so exactly in the west and
3.) both northern & southern hemispheres are EQUALLY illuminated on the side of the planet that the sun is shining on.
For us, here in Las Vegas, the EXACT moment of the equinox happened at 1:22 AM, earlier today. That's it. That one precise moment in time at 1:22 AM was the equinox.
Here in Las Vegas, dawn was at 6:29 AM and sunset was at 6:36 PM; giving us 12 hours and 6 minutes of daylight. Not equal. (But it's only six minutes... you can't forgive 6 minutes?!) No.
There are two reasons for this inequality: First, the sun is not a point in the sky. It is a disk. The apparent size of the sun (it's BIG & CLOSE) matters. Second, the atmospheric refraction of the sunlight in relation to the ltitude of your loction. The erth's atmosphere bends the light adding or subtracting how much actual daylight you have.

Somewhere in the early 2000's, someone (probably my soul twin), usurped the word "Equilux" to mean 'equal day and night'... taken from a lighting term meaning 'equal illumination' or 'equal light'.
The equilux for Las Vegas will occur on September 26.... and guess what? It's the whole day!
But despite that most don't exactly know the astronomical details, the Autumnal Equinox is a time to give "Thanks" for the success of our harvests, whether literal or metaphorically, and to prepare and look to the future return of that bounty.
We pay respects to the coming forces of night and Winter and learn from them as we ourselves prepare for the dark season ahead. The night starts waxing and the day begins waning and we are reminded that nothing ever remains without change.
The Inner Circle Sanctuary celebrates all these aspects of the Autumn Equinox in it's ritual. We honor the Old Ones and pay respects to our ancestors by doing as they did in this season; by giving offerings from the harvest back to Mother Earth and to mark the season.
We hope your Autumnal Equinox was filled with love, laughter, family, and friendship... and a deep and loving connection with all that envelops us.
