1934 until 8 September 1944 just before World War II ended; he was first sent from Milan to the Greek-Albanian front before serving in other areas. He was also a worker in the Pirelli Industries in Milan around this stage. He married fellow catechist Noemi D'Avanzo on 6 May 1944 (the parish priest Pietro Lajolo presided over the marriage rite) and the pair had three children together (son Pier Giorgio in 1945 and daughters Maria Grazia in 1947 and Paola in 1952). He was a diligent catechist who was noted for his intelligence and cheerfulness and was also known to have possessed a good sense of humor when he did his catechizing and evangelizing. Giordani also helped start the Crusade of Kindness movement in the 1950s which received the blessing of the Cardinal Archbishop of Milan Giovanni Battista Montini (the future Pope Paul VI) and the support of the Cardinal Patriarch of Venice Angelo Giuseppe Roncalli (the future Pope John XXIII). Giordani suffered a heart attack in 1962 which forced him to suspend his usual activities for a long period of rest in Deiva Marina. His three children (Pier Giorgio had married Laura sometime in the 1960s) moved to Brazil to be volunteer missionaries in a mission that was organized in Mato Grosso do Sul under the direction of the priest Ugo De Censi. He himself - after discussing the matter with his wife - decided that the pair would join them in Brazil in 1972 to help in their work despite his ill health which was in gradual decline. He and his wife arrived in Brazil from the Genova port (leaving on 21 June 1972) on board the ship "Giulio Cesare" in Poxoreu. He had some knowledge of the Portuguese language but did not become fluent in it. His daughters Maria Grazia and Paola returned to their homeland in October 1972 for work reasons. He died from a heart attack on 18 December 1972 in Campo Grande. He had been speaking to a crowd of people before he felt weak and suffered a fatal heart attack. He reclined his head on the shoulder of Ugo De Censi before turning to his son Pier Giorgio and managed to whisper to him to continue in his stead. His remains were returned home on 23 December and buried in a grave at Vendrogno but moved later to the Basilica di Sant'Agostino in
