National Pig Day- always March 1st

Yellow Pig Day - always July 17th

About Pig Days- -

National Pig Day recognizes and gives thanks to domesticated pigs. For some unknown reason, big, pot-bellied pigs seen in zoos, are often the symbol of the day. Pigs are clever and intelligent animals. But, most people are unaware of this high level of intelligence. They can be taught to do tricks. Some people even keep them as pets. Today is a day to give pigs the respect that they deserve.

National Pig day is celebrated by zoos, too. Activities include Snort Offs, Pig Outs, and online Pig Chats. However you choose, do not miss celebrating this day.

Yellow Pig Day is a mathematician's holiday celebrating yellow pigs (is there such a thing!?!), and the number 17. It is celebrated annually since the early 1960's, primarily on college campuses, and primarily by mathematicians. On campus, Yellow Pig Cake and Yellow Pig Carols are tradition!

If you are a mathematician, spend part of the day thinking and working in multiples of 17. And, while you do so, give a little thought to yellow pigs.

Another Pig Day? There is also some references to a "Pig Day" on January 17th. We found it in online calendars and on Ecard companies. We did not find it in any published documents. We did not find any factual evidence supporting this day on January 17th.

Color of the Day: pink, of course!

Origin of National Pig Day and Yellow Pig Day:

Ellen Stanley, a Texas art teacher created National Pig Day in 1972. Her intent was to to recognize and be thankful for pigs as intelligent domestic animals.

There is no evidence to suggest that this is truly a "National" day, which requires an act of congress.

The Yellow Pig was the brainstorm of mathematicians Michael Spivak and David C. Kelly in the early 1960's. They were students at Princeton University, studying mathematics. History was made as they were listing interesting properties of the number 17 (can you imagine the interesting properties!?). During this thought wave, the yellow pig was born. Most likely, it had 17 toes, 17 teeth, 17 eyelashes, etc. The yellow pig and the number 17 have been linked ever since.
