However, I'm saddened, because I'm also working on my own personal zodiac calendar, inspired by International Talk Like a Pirate Day. Seems to me that the Pirate is an important archetype, but alongside other important figures like the Robot, Monkey, and Ninja. So, I divided the year up evenly and assigned each their own holiday, which put Sneak Like a Ninja Day on March 20th, which isn't even a week after Pi Day. Maybe people will be pied out and not be able to sneak appropriately, or they're practicing their wall-jumping in advance of the ninja day and they'll forget to eat pie.
Either way, I'm going to have to think harder.
