Nochevieja is the Spanish name for New Year's Eve, the night when the twelve grapes tradition takes place. The compound word literally refers to the “old night,” distinguishing December 31 from New Year's Day.
Spanish families and friends often gather for a late meal, watch a televised clock, and eat 12 grapes at the midnight chimes. The celebration may continue with parties, music, and visits after the countdown. Madrid's Puerta del Sol is the best-known public focal point, but the custom is practiced throughout Spain and in many Spanish-speaking communities.
Nochevieja is sometimes confused with Nochebuena, which means Christmas Eve and falls on December 24. Día de Reyes refers to Three Kings' Day on January 6, another important date in the Spanish festive calendar. These names identify separate occasions, even though holiday celebrations may form one extended winter season.
