WARREN, NJ - The longest day of the year arrives on Saturday, June 21 at 6:51 a.m. EDT and the weather forecast is predicting a beautiful day.
As Earth orbits the sun, it tilts 23.5 degrees on its axis. The summer solstice occurs in the Northern Hemisphere, when Earth faces most directly towards the sun.
Solstice comes from the Latin words "sol" and "sistere" meaning "sun stands still"--a reference to how, when seen from Earth, the sun appears to pause before its position in the sky reverses direction.
The solstice marks the first day of summer in the Northern Hemisphere.
In southern England, thousands flocked to Stonehenge to see the sun rise from the vantage point of the 4,000-year-old solar monument.
For those in the Southern Hemisphere, June 21 marks the winter solstice, the shortest day of the year.
