March 14th is recognized as Pi day because the first digits of π(PI) are 3.14. Today is even more significant because the first 5 digits are 3.1415, which would correspond to March, 14th 2015. I contend that Pi Day is a Masonic holiday because Masonry and Geometry were anciently synonymous terms. Pi is arguably the most important mathematical constant, and is absolutely essential to geometry. π is the ratio of a circle’s circumference to its diameter.
Even the Holy Bible alludes to π in 1 Kings 7:23 where it describes the altar inside King Solomon’s temple: “And he made a molten sea of ten cubits from brim to brim . . . and a line of thirty cubits did compass it round about.” These measurements procure the following equation: 333/106 = 3.141509. King Solomon being noted as the first ancient Grand Master of Masons.
