Donald Duck Day is observed on June 09, 2017. It's the official birthday of Donald Duck, the funny animal cartoon character of Walt Disney. Donald Duck first appeared in the 1934 cartoon "The Wise Little Hen" which was part of the Silly Symphonies series of theatrical cartoon shorts. The film's release date of June 9 is officially recognized by the Walt Disney Company as Donald's birthday despite a couple in-universe contradictions. .
Donald is one of the most popular Disney characters. He is an anthropomorphic white duck with a yellow-orange bill, legs, and feet. He typically wears a sailor suit with a cap and a black or red bow tie. Donald is most famous for his semi-intelligible speech and his mischievous and irritable personality. Donald's two dominant personality traits are his short temper and his positive outlook on life. Many Donald shorts start with Donald in a happy mood, without a care in the world until something comes along and spoils his day.
The origins of Donald Duck's name was said to have been inspired by Australian cricket legend Donald Bradman. In 1932 Bradman and the Australian team were touring North America and he made the news after being dismissed for a duck against New York West Indians. Walt Disney was in the process of creating a "friend" for Mickey Mouse when he read about Bradman's dismissal in the papers and decided to name the new character "Donald Duck".
