Sinterklaas (or more formally Sint Nicolaas) traditionally arrives in the Netherlands each year in mid-November (usually on a Saturday) by steamboat from Spain. His birthday is celebrated annually on Saint Nicholas' eve (5th of December). He brings gifts to the children. Sinterklaas is the basis for the North American figure of Santa Claus.
