In Greece, Christmas is called "Kala Christouyenna" (Καλά Χριστούγεννα). It is a time of celebration, family gatherings, and religious observance. Many Greeks also refer to Christmas as "Agios Nikolaos," the Greek name for Saint Nicholas, who is the patron saint of sailors and children. During the holiday season, Greeks exchange gifts, decorate their homes with lights and ornaments, and attend church services to celebrate the birth of Jesus Christ.
