Advent Catholic is a special time in the Catholic Church that leads up to Christmas. It starts four Sundays before December 25th. It is a time for people to get ready for the celebration of Jesus’s birth. During Advent, people go to church, pray more, and do good things for others. It’s like preparing for a big, important guest. You would clean your house and get everything ready. In the same way, Catholics use Advent to prepare their hearts for Jesus. It’s a time of waiting and getting ready for the big celebration of Christmas.
