A pattern (Irish: pátrún) in Irish Roman Catholicism refers to the devotions that take place within a parish on the feast day of the patron saint of the parish, on that date, called a Pattern day, or the nearest Sunday, called Pattern Sunday. In the case of a local folk saint from Celtic Christianity, there may be archaeological remains traditionally associated with the saint, such as holy wells reputed to have healing powers. Often the parish priest will say Mass or lead prayers at such a site, sometimes processing between several locations. In some parishes, Pattern Sunday coincides with Cemetery Sunday, an annual ancestor veneration observance held in cemeteries which typically includes the cleaning and decoration of family graves as well as religious rituals.[1]
