As the earth revolves around the sun, the north pole is tilted toward the sun half the year and the south pole is tilted toward the sun the other half. Today is the day with the longest period of daylight because the sun takes its longest path through the sky. In the Northern Hemisphere the summer solstice always falls on June 20th, 21st or 22nd.
The winter solstice, the shortest day of the year, takes place between December 21st and December 23rd. This occurs when the north pole is at maximum tilt away from the sun.
The name "solstice" is derived from the Latin word "solstitium," which is a combination of sol (sun) and stitium (stand still). Some people say the sun appears to stand still on the solstice.
