The Te Deum is traditionally sung on December 31. It is enriched with a plenary indulgence under the usual conditions, as listed in the Raccolta (1950) n. 684 and in the Enchiridion (1999) n. 26, for those who attend the sung Te Deum on the last day of the year in order to give thanks to God for the blessings received from Him during the whole year.
