The tradition report that the day when the miracle happened in Corbetta, was the first Thursday after Easter and this date remained linked to the celebration of the feast of Our Lady of Corbetta.

It was Pope Pius IV who, on the intercession of his nephew, archbishop of Milan, Saint Charles Borromeo, with the bull  Unigeniti Filii Dei  of 31 August 1562 granted the extraordinary plenary indulgence in jubilee form to all those faithful who, spiritually disposed, were bound to visit the sacred image preserved in Corbetta.
This exclusive privilege, of course, did nothing but increase the number of faithful who flocked to the sacred temple, catalysing the population of Milan and Novara.

Charles Borromeo himself will renew his devotion to the Corbettese Madonna, stopping here in prayer during his pilgrimage to Turin on a visit to the Shroud and other pastoral visits that he made to Corbetta.
