Christmas is celebrated annually on December 25th as the birth of Jesus Christ. It is a public holiday in many countries and celebrated by Christians and non-Christians alike. Popular traditions include gift giving, decorating Christmas trees, attending church services, and the exchange of greeting cards. Santa Claus, known by various names around the world, is said to bring gifts to children during Christmas. Traditions vary between countries but often involve religious observances, special meals, carol singing, and the exchanging of greetings. In El Salvador, children celebrate by playing with fireworks and families have parties with traditional foods like tamales and hot chocolate.
