JUBILEE

A jubilee is a special year of celebration in religious and secular contexts. In the Catholic tradition, it marks a year of grace and forgiveness, occurring every 25 years, or at special times. During a jubilee, people are encouraged to participate in religious practices like pilgrimages and prayers, and they can receive indulgences.
The Opening and Closing of the Holy Doo, in this case, is an important symbolic event during the Jubilee celebrated by the Pope. The Holy Door of St. Peter's Basilica is opened at the beginning of the Jubilee year and closed at the end, marking the start and conclusion of this period of grace. The opening of the door represents a call to spiritual renewal, while its closing symbolizes the completion of the Jubilee and the fulfillment of its sacred time.
