Today is the first day of summer. Google is celebrating the summer solstice with a hot, new Google Doodle.
"When does summer start?" is always one of the most popular questions people ask. Today is the longest day of the year.
There are lots of ways to celebrate the summer solstice. Here are a couple proven ones handed down through the ages:
Modern-day druids (no, not the Grail Movement) meet at England's Stonehenge to celebrate the summer solstice. Many still wear Celtic attire, even though a civilization known as the Beaker People finished Stonehenge a millennium before the Celts were known to exist.
The Tropic of Cancer—the latitude on Earth where the sun is directly overhead at noon on the summer solstice—got its name because the sun appeared in the constellation Cancer.
