 The calendar of 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 the feast day or feast of said saint. The word feast in this context does not mean a large meal, typically a celebratory one but instead an annual religious celebration, the day dedicated to a particular saint. The system arose from the early Christian custom of commemorating each martyr annually on the date of his or her death, or birth into heaven, the date therefore referred to in Latin as the martyr's dies nataly's day of birth. In the Eastern Orthodox Church, the calendar of saints is called a monologon. Monologon may also mean a set of icons on which saints are depicted in the order of the days of their feasts, often made into panels.
