His birthday is March 14...aka 3.14
pi = 3.14 so if he was alive he might have celebrated on March 14...??? but Einstein did not discover pi........the only pi he ever made was pie that he baked in the oven Plus March 14 was also albert einsteins birthday, so it would make sense to also celebrate pi on march 14.

I think the question would more correctly be posed as "why did the United States, decide to celebrate Pi Day on Albert Einstein's birthday?" Pi Day was started by Larry Shaw in 1988. Einstein was born in 1879 and died in 1955. (He was already dead when Pi day came into existence, so there is no way he could have been born on Pi day.)

no, it was William Jones. Albert Einstein founded E=MC2.
