Manhattanhenge, Manhattan Solstice, New York City, United States

Manhattanhenge (sometimes referred to as the Manhattan Solstice) is a semiannual occurrence in which the setting sun aligns with the east–west streets of the main street grid in the borough of Manhattan in New York City. The term is derived from Stonehenge, at which the sun aligns with the stones on the solstices. It was coined in 2002 by Neil deGrasse Tyson, an astrophysicist at the American Museum of Natural History. It applies to those streets that follow the Commissioners' Plan of 1811, which laid out a grid offset 29.0 degrees from true east–west. (The 29.0 degrees should be added to true east and west, making the western bearing approximately 299.0 degrees.)
