Victoria Ritvo and John Pribyl launched Hengefinder, a website and app that lets users enter a city or address to find the nearest street or canal where sunset aligns with the grid.
The tool works by matching a road’s bearing against the sun’s changing sunset azimuth, identifying the few dates each year when the two angles line up.
Manhattanhenge returns from May 28 through July 12, but similar events also appear in cities including Chicago, Baltimore and Toronto, typically twice a year.
Neil deGrasse Tyson coined the term Manhattanhenge in 1997, comparing the effect to Stonehenge’s solstice alignment; Ritvo says the app opens that phenomenon to places far beyond New York.
