Halloween

Halloween traces back to Samhain, an ancient Celtic festival marking the boundary between the living and the dead, later folded into the Catholic calendar as All Hallows’ Eve — making it, like Day of the Dead, a holiday built on the collision of pre-Christian ritual and European Catholic tradition, just from a different continent’s roots.

Here is how Halloween plays out across New York City, from the Village Halloween Parade to the Jackson Heights Halloween Parade, to the Tompkins Square Halloween Dog Parade.
