Pi Day, celebrated on March 14 (3/14), honors the mathematical constant Pi, which represents the ratio of a circle's circumference to its diameter and has practical uses in various fields. Originating in 1988, the holiday gained national recognition in 2009 and is marked with pie-themed events and activities, including NASA's "Pi Day Challenge." Pi's significance extends to science, engineering, and even NASA's daily operations, while also serving as a tribute to Albert Einstein, whose birthday coincides with the celebration.
