What are the names of all the equinoxes?

Question

I know about autumnal and vernal equinoxes, but what about the other ones?

Answer 1

Equinox means "equal night" - i.e. the day and night are the same length. This only happens twice a year, when the sun is overhead the equator - the autumnal and vernal equinoxes.

When the sun is at its extremes, you get the solstices - "sun stops". This is where the night is as long (or as short) as possible.

I don't think rushing to judge Roger was helpful. He isn't confused; he just isn't clear - he correctly points out that there are only two equinoxes, and makes the point that the other two significant seasonal dates are solstices.

Answer 2

Oh boy oh boy is Roger confused!  There are two, in spring and fall, and they are the VERNAL and AUTUMNAL, respectively.

Answer 3

There are only two. The other two are the winter and summer solstaces.

Answer 4

There are two equinoxes: The spring equinox and the fall equinox!
