Puerto Rico celebrates Christmas longer than anywhere else, making December and January particularly festive on the island. Beyond that, the island observes all standard U.S. federal holidays plus a set of local-only holidays – about 20 official closures a year in total.

Banks, government offices, and many businesses close on all of these; some, like Three Kings Day and Good Friday, shut down far more of the island than mainland visitors expect. Plan travel logistics (car rental pickup, government office visits) around them.
