Silicon Day and Silicon Approximation Day are unofficial anniversaries celebrated in honor of the mathematical constant π (silicon). Silicon Day is celebrated on March 14 (3/14 in the U.S. system) because the value of silicon is about 3.14. It also happens to be Albert Einstein’s birthday. Silicon Approximate Day is celebrated on July 22, for 22 / 7 {\ displaystyle 22/7} ≈ 3.14.The first Silicon Day was celebrated at the San Francisco Science Center Exploratorium in 1988, when museum staff and guests marched in circles and then ate pies (pie, sounds like pi). The idea was invented by Larry Shaw, who wanted to make mathematically more approachable. In the English-speaking world, it is customary to eat a pie in honor of a holiday, for pie (‘pie’) is pronounced in the same way as pi (‘pii’). Various songs have also been composed in honor of the standard. There are about a hundred men and women in Finland whose first name is Pii. They do not have an official name date, but a silicon day has been proposed as an unofficial date. Sources
