On June 28, 2008, the sun set in New York City at approximately 8:30 PM Eastern Daylight Time (EDT).
This late sunset reflects New York's northern latitude (40.7° N) near the summer solstice, when the Northern Hemisphere experiences its longest daylight hours. Civil twilight—when outdoor activities remain feasible without artificial light—extended until roughly 9:00 PM.
For context, the summer solstice in 2008 occurred on June 20, so June 28 was just eight days past peak daylight. Sunset times gradually shift earlier through July and August.
