Nochevieja, or New Year's Eve, is celebrated on December 31st in Spain and many Spanish-speaking countries. It marks the final night of the year, where people gather with family and friends to bid farewell to the old year and welcome the new one. A popular tradition during Nochevieja is eating twelve grapes at midnight, one for each stroke of the clock. Each grape represents good luck for the upcoming year. Many also celebrate with fireworks, parties, and special meals, making it a festive occasion filled with joy and hope for the future.
