The 2025 Jubilee will officially open on 24 December 2024 at 7 p.m., with the rite of the Opening of the Holy Door at St Peter's Papal Basilica by the Holy Father, who will then preside over the celebration of Holy Mass on Christmas Eve inside the Basilica.

In 1867 Don Bosco dedicated a side altar to the Sacred Hearts of Mary and Jesus in the Basilica of Mary Help of Christians; Fr Michael Rua some years later, in 1891, changed it and dedicated it to Saint Francis de Sales and lately it was rededicated to Saint Dominic Savio.

In August 1877 Don Bosco founded the "Bollettino Salesiano" (Salesian Bulletin). Even before this original creation, however, Don Bosco had realised that his work with young people would be effective if he had  books available suitable for poor and abandoned youth. And so he had begun to write small works for the people in general and for young people.
