Manhattanhenge, additionally called the Manhattan Solstice, is an occasion during which the setting sun or the rising sun is lined up with the east– west avenues of the primary road lattice of Manhattan, New York City. The dusks and dawns each adjust two times per year, on dates equitably divided around the late spring solstice and winter solstice. The nightfall arrangement happens around May 28 and around July 13.
The dawn arrangement happens around December 5 and around January 8. The term "Manhattanhenge" was promoted by Neil deGrasse Tyson, an astrophysicist at the American Museum of Natural History and a local New Yorker. It is a reference to Stonehenge, an ancient landmark situated in Wiltshire, England, which was built so the rising sun, seen from the focal point of the landmark at the season of the midyear solstice, lines up with the external "Foot sole area Stone". In agreement with the Commissioners' Plan of 1811, the road framework for the vast majority of Manhattan is pivoted 29° clockwise from genuine east-west.
In this way, when the azimuth for nightfall is 299° the dusk lines up with the bouleds on that framework. A more noteworthy visual exhibition, and the one usually alluded to as Manhattanhenge, happens several days after the principal such date of the year, and two or three days before the second date, when a passerby looking down the centerline of the road westbound towards New Jersey can see the full sun based circle marginally over the skyline and in the middle of the profiles of the structures. The date shifts are because of the dusk time being the point at which the remainder of the sun just vanishes beneath the skyline.
