Summer Solstice 2013, Longest Day Of The Year

While many calendars identify the summer solstice as occurring on Friday, June 21, it actually occurs in Los Angeles at 10:04 p.m. on Thursday.

The summer solstice is the moment when the Earth's orbital motion points the Earth's North Pole most closely in the direction of the Sun.

In the Southern Hemisphere, today marks the first day of Winter Solstice. "This date marks the start of astronomical summer in the Northern Hemisphere, making it the longest day of the year!"

Both the winter and summer solstice events are traditionally celebratory, and in many cultures throughout history they have held a great deal of significane.

National Geographic said that the solstices are the results of Earth's north-south axis being tilted 23.4 degrees relative to the ecliptic, the plane of our solar system.

"This tilt causes different amounts of sunlight to reach different regions of the planet during Earth's year-long orbit around the sun", the report said.

During the summer solstice, the sun appears to shine farthest to the north of the equator, over the Tropic of Cancer, and begins its trip southward.

Though just because they say "directly overhead", doesn't really mean it will be directly overhead for everyone.

So with the 2013 summer solstice finally marking the first official days of summer, are you excited to start the season?
