Pi Day: March 14, 2023

Press Release Number CB23-SFS.33

In 2009, the U.S. House of Representatives passed “H.Res.224 - Supporting the designation of Pi Day...”

“Whereas Pi can be approximated as 3.14, and thus March 14, 2009, is an appropriate day for ’National Pi Day’: Now, therefore, be it Resolved, That the House of Representatives—

(1) supports the designation of a ’Pi Day’ and its celebration around the world;

(2) recognizes the continuing importance of National Science Foundation’s math and science education programs; and

(3) encourages schools and educators to observe the day with appropriate activities that teach students about Pi and engage them about the study of mathematics.”
