Get ready....a bunch of special days will soon occur....
Why should the number pi get all of the special attention, when we also could celebrate the following days as well:
The list could go on...perhaps we could search out more math constants and thereby create a math holiday to celebrate every week....and our students might learn some more mathematics as well.
- January 1st at 2:35 pm: Fibonacci-Day [Uses sequence 1, 1, 2, 3, 5...]

Or, your students could creatively invent some new numerical holidays....please send them for possible inclusion on this list (with credit given of course). Note that the months August-December are begging for some attention.
I know. All of this is folly amidst weird numerical celebrations (i.e. some are actual days...you determine which). They may seem irrational to outsiders....but then what can be expected, given so many of the numbers involved are irrational!
