Platypus Day

 (also known as National Platypus Day) is a Phineas and Ferb promotion and accompanying marathon by Disney Channel US and Disney XD in an attempt to "create a new holiday to celebrate one of our most valuable semi-aquatic undercover agent," as Major Monogram describes it. The event was on Saturday, March 5, 2011. Based on it's airdates on 2011 and 2012, Disney has apparently chosen the first Saturday of March to celebrate the date every year. The event was on Saturday, March 5 in 2011, and was held on Saturday, March 3 in 2012.
