Sinterklaas is observed on December 05, 2025. Sinterklaas is a traditional winter holiday figure. He is celebrated annually on Saint Nicholas' eve in the Netherlands. Sinterklaas is an elderly, stately and serious man with white hair and a long, full beard. He wears a long red cape or chasuble over a traditional white bishop's alb and sometimes red stola, dons a red mitre and ruby ring, and holds a gold-coloured crosier, a long ceremonial shepherd's staff with a fancy curled top. He carries the big book of Saint Nicolas that tells whether each child has been good or naughty in the past year. He traditionally rides a white horse. (With material from: Wikipedia)
