This offering revolves around the feasts of two great adolescent saints who were heroic martyrs of chastity —St. Pelagius of Cordoba (June 26th) and St. Maria Goretti (July 6th)—. It concludes with a bonus «grand finale» day on July 7th because it holds the martyrdom of two significant heavenly intercessors: Bl. Peter To Rot —a young man, champion of the sanctity of marriage— and St. Mark Ji Tianxiang —a «surprise saint» described in the order of days tab. 

However, Divine Providence arranged these twelve days in such a way that not only do we celebrate these holy champions of purity as the main bookends of this train of days of grace; but, in addition, our rich Catholic liturgy also makes us partakers —during each of these days in between— of different festivities of other heroic witnesses of holy chastity.

Thus, with at least one heavenly intercessor per day, you'll be assured of an increased value to the merits of your earthly offering on behalf of all souls in grave need for purity, especially those of the youth!
