In the United States, many churches hold special services on Palm Sunday, where congregants receive palm branches and sing hymns to celebrate the occasion. Some people also decorate their homes with palm fronds to acknowledge the holiday. Overall, Palm Sunday is an important day for Christians in the US and worldwide, as it marks the beginning of Holy Week leading up to Easter.
