National Pi Day!

Today we celebrate that memorable day on March 14, 1592 when Pi Day became an official holiday!
At 6am, all 535 mathematicians and mathematics students at Dublin University convened for a scheduled 89-minute colloquium. It wasn't the original 79 minutes as reported at the time. The purpose was to expand the previously-calculated 32 decimal points of Pi to 38. 46 of the students spent more than 264 minutes on the task, but calculated the solution! 33 of them speculated that the number of decimal places might be as large as 83. Of the last 279 minutes of the day-long session -- the session went over-long -- 50 of them were spent confirming the numbers. 288 of the attendees signed the Pi Accord that day. 41 signed it conditionally. Only 9 said "no." To celebrate, the assembly ratified this date as Official Pi Day.
7 of the attendees vowed to establish a second colloquium in 1693. 99 people showed up then. At that point, the decimal count was up to 375, effectively 10 times what it had been a century earlier.
