FAQ
Why do the dates change from year to year?
Because the tropical year is about 365.2422 days, so each event drifts about six hours later annually until a leap day pulls it back. Over a leap cycle the date moves within a range of a day or two.
Why are the seasons different lengths?

Is the equinox exactly 12 hours of daylight?
Not quite. Atmospheric refraction lifts the Sun\
