A name day is a tradition celebrated in many countries of Europe and the Americas. It is the celebration of the day of the year that is associated with one's baptismal name.

Name days are an ancient practice, a relic of a time when birthdays were indulgences reserved for the elite. The tradition began centuries ago as a way of venerating the Greek gods and Christian saints. In recent years, name days have experienced something of a renaissance. Largely divorced from their religious origins.

Whereas birthdays celebrate individuals, name days are collective holidays marked by national calendars, radio stations and news outlets, days when people are feted just for answering to particular name. Name Days can vary from country to country.
