What are the summer solstice and winter solstice?
user
The solstices are when the days and nights are exactly of the same length. The summer solstice, which in the northern hemisphere occurs on June 20th or 21st, is the longest day and the winter solstice, which occurs on December 22nd or 23rd, is the shortest day.

That's partially wrong. The solstices have nights and days equal in length if they are also the longest and shortest days of the year.

Oh, you're right! I'm going to update the page to correct that.

Okay, great. What are the equinoxes?
