Pi(e) Day

I was just reminded that today is that special day: 3.14 (2008).

Around the year 480, "the Chinese mathematician Zu Chongzhi gave the approximation π = 355/113, and showed that 3.1415926 < π < 3.1415927, which would stand as the most accurate value for π over the next 900 years."*

I wonder if on March 13, 1592, anyone realized what a neat-o day it was?
