The Exaltation of the Holy Cross is observed worldwide every September 14, commemorating the dedication of the Church of the Holy Sepulchre in 355. This feast is closely linked to the discovery of the True Cross, which, according to tradition, was found by Saint Helena in 326 during her pilgrimage to Jerusalem. Following the discovery, a church was built at the site, completed in 335, with its dedication occurring on September 13. The next day, the True Cross was publicly venerated by clergy and the faithful, leading to the establishment of September 14 as the Feast of the Exaltation of the Holy Cross. On this day, many Western Christian churches, including Roman Catholic congregations, observe the occasion by using red as the liturgical color, with priests donning red vestments during services. This feast is one of several holidays dedicated to the Holy Cross within the Christian tradition.
