一年两次的罕见日落美景在纽约上空罕见上演, 与英国撒利兹堡(Salisbury)平原上的史前时期巨大石柱群景观一样, 这一独特的城市奇景也颇为壮观, 该现象被称为“曼哈顿悬日”.

该景观一年仅有两次, 而且还不是年年都有, 整个纽约不夜城便沐浴在阳光下. 在“曼哈顿悬日”出现的这几天里, 当太阳落下时, 在纽约曼哈顿地区的格网街道的排列形式就如同巨大石柱群布局一样, 每一处的十字路口都沐浴著金灿灿的阳光长达15分钟.

Manhattanhenge (sometimes referred to as Manhattan Solstice) is a semi-annual occurrence in which the setting sun aligns with the east-west streets of Manhattan's main street grid. 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 28.9 degrees from true east-west.

At sunset, a traveler along one of the north-south avenues on the West Side while 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. The two corresponding mornings of sunrise right on the center lines of the Manhattan grid are approximately December 5 and January 8. As with the solstices and equinoxes, the dates vary somewhat from year to year.

这些街道符合从东西方向偏移28.9度的规律. 由於这些街道刚好在东西线上, 因此该景观出现的时间刚好与春分和秋分时间一致, 形成了自然与人工建筑的和谐搭配. 当太阳落到了纽约克莱斯勒这座具有立体装饰艺术的大厦背后时，整个大厦便显示出一层金色光泽.
