Manhattanhenge, Manhattan Solstice, New York City, United States

At sunset, a traveler along one of the north-south avenues on the West Side looking east can observe the phenomenon indirectly, being struck by the reflected light of the many windows which are aligned with the grid. An observer on the East Side can look west and see the sun shining down a canyon-like street.
The dates of Manhattanhenge are usually May 28 and July 12 or July 13 (spaced evenly around Summer Solstice).
