And here's Boston:
Well that explains why I feel like winter nights are somehow worse and darker than summer ones. In summer, it's mostly not night at all: the twilight periods eat half the clock-nighttime. In winter, twilight gets cut in half and combines with the losses of daylight to extend nighttime.
Nowhere in Manhattan is that true (though perhaps I'll grant that a building might occlude the sun, but you're exaggerating). Conservatively, if we pick Albany, NY as the "northernmost extent of Manhattan", the earliest sunset is ~4:21pm.
