Christmas is celebrated in Spain on December 25th, just like in many other countries around the world. However, the holiday is celebrated in a slightly different way compared to other countries. In Spain, the Christmas season officially starts on December 8th, which is the feast day of the Immaculate Conception. During this time, families typically decorate their homes with beautiful lights and nativity scenes. The main event of the season is Christmas Eve, when families gather together to have a large dinner and exchange presents.
