January 6: Phi Day
Geek Holiday: Phi Day!
The fabulously irrational number φ has two decimal representations (1.618… and -0.618…) so it can be celebrated both on January 6 and on June 18. Crazy, huh? Leave it up to those wacky mathematicians to create two viable party dates from one number. Double the φun, right? Phi is also important to artists and architects because it is the core of the basic aesthetic proportion known as the Golden Ratio or Golden Mean.Geek
