In
another thread it became apparent that there may be some disagreement about what the equinox is.
The equinox is the moment when the sun is directly overhead the equator.
On the equinox, at all places on earth where it is possible to observe sunrise and sunset, the sun rises directly to the east, and sets directly to the west. On all other days the sun rises and sets in some slightly different direction from due east/west.
The length of the day is approximately equal to the length of the night at all points on earth that can observe sunrise and sunset on the equinox.
Does anybody disagree with these statements?
