The holiday season in Spain is celebrated from December 24th until January 6th, with Christmas Eve being the most important day of the season. The day is typically spent with family, attending a midnight Mass and then sharing a meal together. On Christmas Day, children wake up to find gifts under the tree or at the foot of their beds. The celebrations continue for the next few days with parties and special events until January 6th, known as the Epiphany, which marks the end of the holiday season.
