Puerto Rico celebrates the New Year on January 1st, aligning with the Gregorian calendar used by most of the world.
Festivities typically begin on New Year's Eve (December 31st) and continue into the early hours of January 1st. Traditions include family gatherings, fireworks, music (like plena and salsa), eating 12 grapes at midnight for luck, and the "Año Viejo" ritual of burning effigies to symbolize leaving the past behind.
