Manhattanhenge is when the sun sets on Manhattan’s street grid

Manhattanhenge are days when the sun lines up with Manhattan’s crosstown street grid.

The name is a reference to the way the prehistoric monument Stonehenge in England is designed to frame the sunrise of the summer solstice and the sunset of the winter solstice. Those days mark the change of seasons.

The Manhattan grid alignment is accidental, but it is still a little magical when the sun rises or sets straight across Manhattan streets.

Manhattanhenge happens twice on summer sunsets and twice on winter sunrises. Plus each Manhattanhenge is actually two days. One day the sun’s full disk aligns with the street grid. The other day half the sun’s disk aligns with the street grid.

There are eight Manhattanhenge days every year.

Best Manhattanhenge Viewing Spots

Wide cross streets are the best viewing spots. Go at least an hour early if you want to get a good spot. The best spots get crowded.

• 79th Street
• 59th Street
• 42nd Street includes the Chrysler Building.
  The Tudor City Bridge is a good spot for Manhattanhenge sunsets.
• 34th Street includes the Empire State Building
• 14th Street

It’s good to be alive.

Looking directly at the sun is dangerous

It has to be said that looking directly at the sun can burn your eyes.

Be careful even using solar viewing glasses. During recent eclipses, many people hurt themselves because their viewing glasses did not actually provide protection.
