A watchnight service (also called Watchnight Mass) is a late-night Christian church service. In many different Christian traditions, such as those of Moravians, Methodists, Catholics, Lutherans, Anglicans, Baptists, Adventists and Reformed Christians, watchnight services are held late on New Year's Eve, which is the seventh day of Christmastide. This provides the opportunity for Christians to review the year that has passed and make confession, and then prepare for the year ahead by praying and resolving. The services often include singing, praying, exhorting, preaching, and Holy Communion.
