Christian celebrations are important events that commemorate significant moments in the life of Jesus Christ and the Christian faith. Major celebrations include Christmas, which marks the birth of Jesus, and Easter, which celebrates His resurrection. These events often involve special church services, family gatherings, and various traditions that vary by culture. In addition to these major holidays, Christians also observe other celebrations such as Pentecost, which commemorates the descent of the Holy Spirit, and Advent, a season of preparation leading up to Christmas. Each celebration has its own unique customs and rituals, reflecting the diverse practices within Christianity.
