The exchanging of gifts is one of the core aspects of the modern Christmas celebration, making it the most profitable time of year for retailers and businesses throughout the world. Gift giving was common in the Roman celebration of Saturnalia, an ancient festival which took place in late December and may have influenced Christmas customs.[55] On Christmas, people exchange gifts based on the tradition associated with St. Nicholas.The best known of these figures today is red-dressed Santa Claus, of diverse origins. The name Santa Claus can be traced back to the Dutch Sinterklaas, which means simply Saint Nicholas. Nicholas was a 4th-century Greek bishop of Myra, a city in the Roman province of Lycia, whose ruins are 3 kilometres (1.9 mi) from modern Demre in southwest Turkey.[169][170] Among other saintly attributes, he was noted for the care of children, generosity, and the giving of gifts. His feast day, December 6, came to be celebrated in many countries with the giving of gifts.[93]
