Manhattanhenge is a twice-yearly sunset phenomenon in New York City in which the setting sun aligns with the Manhattan street grid. Observers on the relevant avenues and streets see the sun appear to rise or set between skyscrapers, giving the effect of the sun meeting the horizon in a “canyon” of buildings. Several outlets describe Manhattanhenge as a predictable event that draws both residents and visitors who plan their viewing around the alignment. The concept is tied to the city’s grid layout and the sun’s seasonal position, so the effect occurs during specific times of year rather than daily. While details on exact dates and viewing locations are not included in the provided excerpts, the reporting agrees on the core description: Manhattanhenge happens twice each year, it involves the sun’s alignment with Manhattan’s streets, and it is observed as the sun sinks below the horizon framed by tall buildings. Overall, sources present Manhattanhenge as a clear, skyline-focused spectacle created by astronomy and the geometry of the city.
