Yellow Pig Day

Yellow Pig Day is a mathematics holiday observed all around the world on July 17 of every year. Yellow Pig Day celebrates the number 17. The number 17 is celebrated because it is a unique prime number and has much importance in mathematics. 17 is sum of the first four prime numbers 2, 3, 5, and 7. Prime numbers have its uniqueness of getting divided by 1 or by itself. A psychology study reveals that many people tend to choose the number 17 when they are asked to select a number from 1-20.

History of Yellow Pig Day

Yellow Pig Day was created by two mathematician that is Michael Spivak and David C. Kelly in the year 1960. They were students at Princeton University and were studying mathematics. It is assumed that they were making research on interesting proprieties of the number 17, which led to the invention of the Yellow Pig Day. But anyways the reason for naming the day yellow pig is unclear. The yellow pig mentioned by them is believed to have 17 toes, 17 teeth, 17 eyelashes, etc. and the number 17 has always been linked with it ever since. David C. Kelly ran Hampshire College Summer Studies in Mathematics and also lectured and developed classes based on it. Micheal Spivak had written several math books which had references to yellow pigs and the number 17 indirectly. Spivak always had the habit of referring something to something; some books contain references to Chinese Policeman.
