When is Saint Thomas the Apostle’s feast day? 

The Church celebrates the Feast of Saint Thomas the Apostle on July 3rd. Though Saint’s feast days are typically celebrated on the date of their death, Saint Thomas’ exact date of death is unknown. The date of July 3rd was chosen to commemorate the date his relics were transferred to Edessa (in modern Turkey), possibly from South India, where Christians claim Thomas as the Apostle who evangelized them.
