About the Holiday
Yellow Pig Day, held annually on July 17th, is a humorous celebration created and observed by mathematicians at Hampshire College in Amherst, Massachusetts. Yellow Pigs Day was started by Michael Spivak and David C. Kelly who were listing the interesting properties of the number 17 (hence the 7/17 for the holiday's date, where 17 is the 7th prime number) and somehow a 17 eyelashed yellow pig was born.[1]
The day is typically marked by exchanging gifts relating to yellow pigs, mathematics, the number 17, singing yellow pig songs, and playing Ultimate. Some celebrations for this day occur on May 17th and September 17th.
