Saints days

traditional Christian method of organizing a liturgical year by associating each day with one or more saints

The calendar of saints is a traditional Christian method of organizing a liturgical year by associating each day with one or more saints and referring to the day as that saint's feast day. The system arose from the very early Christian custom of annual commemoration of martysr on the dates of their deaths, or birth into heaven, and is thus referred to in Latin as dies natalis ("day of birth").
