la cena de Nochebuena Christmas Eve dinner
Most Spanish and Latin American families eat their Christmas dinner on Christmas Eve, or Nochebuena, unlike families in the States or the UK, who usually eat their Christmas dinner on Christmas Day (el día de Navidad).
Traditional Latin American Christmas Eve celebrations also include going to Midnight Mass, la Misa del Gallo, named after the rooster (or gallo) that heralds the break of day.
