ROME — Pope Francis and top officials of the Roman Curia will leave the Vatican March 1-6 for their annual Lenten retreat, the Vatican announced.

And, as is customary when first publishing the pope’s calendar for Holy Week, the Vatican did not provide the time or place for his celebration of the Mass of the Lord’s Supper on Holy Thursday, April 9. Francis has made it a tradition to celebrate the Mass and foot-washing ritual at a prison or detention center, refugee center or rehabilitation facility.

Here is the schedule of papal liturgical ceremonies for February, March and April released by the Vatican Feb. 12 (times listed are local):

— Feb. 26, Ash Wednesday, 4:30 p.m. penitential procession from Rome’s Church of St. Anselm to the Basilica of Santa Sabina for Mass with the imposition of ashes.
