Consider doing something round, today.

Pi Day is celebrated everywhere on March 14th (3/14), since π is the mathematical symbol for the ratio of the circumference of a circle to its diameter – numerically, approximately 3.14159.

But this irrational and transcendental number can go on and on, millions of digits beyond the decimal point, never repeating itself, never forming a pattern.

We know we had you at ‘irrational and transcendental’.

So let’s celebrate. Recite as many of the infinite digits of Pi as you can remember, memorizing is good for the brain anyway. Organize π-reciting contests. Eat pie. Eat pizza, it counts as pie. Eat anything round (and edible, please). Eat cake with friends (it’s also Einstein’s birthday, if you need a reason); eat donuts, eat cookies. Walk around in circles, have circular thoughts, throw pies at your colleagues, appreciate the casual relation between the ratio of the circumference of a circle and the English word for pastries filled with sweet goodness.

Or savory. We don’t want to impose. And have a nice π day.
