The pope said that the Vatican’s Dicastery for Evangelization will publish resources to help Catholic communities to more fully participate in the Year of Prayer. The Holy See Press Office has also announced that a press conference on the Year of Prayer will take place on Jan. 23.

The Vatican and the city of Rome are expecting an estimated 35 million people to flock to the Eternal City for the 2025 Jubilee Year of Hope — the first ordinary jubilee since the Great Jubilee of 2000.

A jubilee is a special holy year of grace and pilgrimage in the Catholic Church. It typically takes place once every 25 years, though the pope can call for extraordinary jubilee years more often, such as in the case of the 2016 Year of Mercy or the 2013 Year of Faith.

Jubilees have biblical roots. The Book of Leviticus called for jubilee years to be held every 50 years for the freeing of slaves and forgiveness of debts as manifestations of God’s mercy. The practice was reestablished by Pope Boniface VIII in 1300.

The 2025 Jubilee Year begins on Dec. 24, 2024 (Christmas Eve), and concludes on Jan. 6, 2026.

The Holy Doors are a central part of any jubilee. These doors, found at St. Peter’s Basilica and Rome’s other major basilicas, are sealed from the inside and opened during a jubilee year.
