At the time of the Fall equinox (always near September 21),
and the Spring equinox (always near March 21), the days and
nights are nearly the same duration.
The shortest days of the year are around the Winter solstice ...
always near December 21.
The longest days of the year are around the Summer solstice ...
always near June 21.
Eclipses can happen on any day or night of the year. They're
totally not connected with the equinoxes or solstices.
