A name day is a tradition in many countries in Europe and America that consists of celebrating the day of the year associated with one's given name.

The celebration of name days has been a tradition in Catholic and Orthodox countries since the Middle Ages. The custom originated with the Greek Orthodox and Roman Catholic calendars of saints, where believers, named after a particular saint, would celebrate that saint's feast day. However, in many countries there is no longer any explicit connection to Christianity. The celebration of name days remains more popular in Southern and Eastern Europe rather than in Northern Europe. In each country, there is a different list called Name Day Calendar.

Some names can be celebrated on more than one day of the year like Valentina or Valentine being celebrated on the 25th of July and on the Catholic Saint Valentine's Day - 14th of February.
