No, Yom Kippur is not a person! Yom Kippur means "the Day of Atonement." It is a Jewish Holiday of complete fasting (even from water) and introspection. It is actually a happy day, with festive meals before and after. We are happy because God promises to forgives our sins on this day, if we truly resolve to be better. (See Levicticus 23:26-32)
