A Jacobean Holy Year (Galician: Ano Santo Xacobeo), also known as the Compostela Holy Year, is a Catholic celebration that takes place in the Spanish city of Santiago de Compostela, Galicia. It occurs in the years in which 25 July, the Feast of Saint James, falls on a Sunday. This occurs with a regular cadence of (6, 5, 6, 11) years, so that fourteen Jacobean Holy Years are celebrated every century (except when the last year of a century is not a leap year, resulting in a lapse of 7 or 12 years).
The celebration of each holy year grants a plenary indulgence to all those faithful who: visit the Santiago de Compostela Cathedral, say a prayer (at least the Apostles' Creed or the Our Father), and pray for the intentions of the Pope. It is also recommended to attend Holy Mass and receive the sacraments of penance and communion; that is, to confess and take communion (in the fifteen days before or after the visit to the cathedral). It is customary, moreover, to access the cathedral through the Holy Door, which is opened only on the occasion of the Holy Year.
