Today is π-day, because of the approximation 3.14. It seems that the holiday had not, unfortunately, been invented in 1592.
Wikipedia lists a few other days that approximate π:
- April 26 (when the distance of the Earth's orbit divided by the time it has traveled so far is equal to pi; on leap years the 25th)
- July 22 (22/7 in some date formats, a popular approximation of pi)
- November 10 (the 314th day of the year; on leap years the 9th)
- December 21, 1:13 p.m. (the 355th day of the year, celebrated at 1:13 for the Chinese approximation 355/113)
