In some Roman Catholic and Eastern Orthodox countries such as फ्रांस, Poland, Russia, Bulgaria, Hungary, or Greece, it is common to have a 'name day'/'Saint's day'. This is celebrated in much the same way as a birthday, but is held on the official day of a saint with the same Christian name as the birthday person; the difference being that one may look up a person's name day in a calendar, or easily remember common name days (for example, "John" or "Mary"); however in pious traditions, the two were often made to concur by giving a newborn the name of a saint celebrated on its birthday, or even the name of a feast, for example, "Noel" or "Pascal" (French for Christmas and "of Easter").
