While musing about pumpkin-creamcheese pie I realized that I'd completely forgotten that today is Pi Day! Alas, it was already past the traditional 1:59pm celebration time.
The "ultimate" pi moment occurred on March 14, 1592, at 6:53 AM and 58 seconds. When written in American-style date format, this is 3/14/1592 6:53.58, which corresponds to the value of pi to twelve digits: 3.14159265358. However, considering this was well before any kind of standardized world time had been established, and the general public had no concept of π, the occurrence likely went unnoticed.
