# Did you know, Pi day is also Einstein’s Birthday?

**Pi Day** is an annual celebration commemorating the mathematical constant π (pi). Pi Day is observed on March 14 (or 3/14 in the U.S. *month/day* date format), since 3, 1, and 4 are the three most significant digits of π in the decimal form. In 2009, the United States House of Representatives supported the designation of Pi Day. (Wikipedia)^{}

National Pi Day is actually a U.S. holiday.The House of Representatives passed House Resolution 224 in 2009, designating March 14 as National Pi Day. The resolution “encourages schools and educators to observe the day with appropriate activities that teach students about Pi and engage them about the study of mathematics.” (Source:http://www.usatoday.com/story/tech/2014/03/13/pi-day-friday-31415/6369483/)
