can someone explain what equinox is

When it officially becomes autumn or spring etc. It is usually worked out by the numbers of sunlight hours or the sun angle like on this one everywhere in the world on that day will have 12 hours of daylight and 12 hours of night.

I think it is the point in time at which the Sun's 'overheadness' crosses from the Northern to the Southern hemisphere, and vice verca?

To make it a bit easier to understand.

23 Sep 2010

(Sunrise) 06:56

(Sunset)19:06

(Length of day)12h 09m 26s

(Time of daylight losing until Dec 21st) − 4m 12s

Or to put it into context, break the Calendar down into half first. You have Midwinter where daylight is at its shortest and night is at its longest. Then you have Midsummer 6 months later, as theres 12 months in a year) where daylight is at its longest and night is at its shortest.

Between these 2 Mid-Sols there are Equinoxes, where the transition from the short and long daylight have to counterbalance each other out. This is when Day and Night become equal in the 1/4 Calendar or Equinoxes. This happens in March (20th/21st) and September (22nd/23rd) of every year also.

yep, equi = equal and nox = night.

So equal night.

Other than that, the explanation of its other terms has been answered above.

It seems a little late this year. How often does the Equinox drift out to the 23ed. If you wre at the north pole the sun would just be setting, not to reappear untill the Spring Eqiniox

More or less. It's when sun moves southward across the celestial equator and fall begins in the NH. If you are in the States of course.:D

Just in case, the celestial equator divides the sky into southern and northern hemispheres, just as the earth's equator divides the earth into two hemispheres.

Oops, sorry if this has already been answered.:fool:
