NATIONAL YELLOW PIG DAY
National Yellow Pig Day is observed on July 17 and is a holiday especially for the mathematicians of the world!
Look for the not so random occurrence of the number 17. Look! Yellow pig!
HOW TO OBSERVE
Brush up on your calculus and round up your yellow pigs. Post on social media using #NationalYellowPigDay.
Our research found that National Pig Day originated sometime during the early 1960s when two mathematicians named Michael Spivak and David Kelly analyzed the random properties of the number 17 and a mysterious yellow pig. It seems the process became excessive and professional. Kelly lectured and developed classes around it. Spivak published several mathematics texts, while not based upon it, does subtly reference the number 17 and Yellow Pig.
There are over 1,500 national days. Don’t miss a single one. Celebrate Every Day with National Day Calendar!
