Welcome back to Fun with Calendars. As you probably know, May 4 is now widely referred to as May the Fourth, a play on Star Wars’ famous saying, “May the Force be with you.” March 10 has evolved into the Nintendo-centric Mario Day, because “Mar10.” And let’s not forget the best day in the whole wide world: March 14, otherwise known as Pi Day because of the eponymous mathematical constant that begins with “3.14.”
Wait, we’re celebrating math this weekend? No, food: Say it out loud and it becomes “Pie Day.” Hence an abundance of deals and promotions centered on pizzas and pies. Below I’ve rounded up some of my favorites, as I do every year, though this list is by no means complete. There may be local stores and restaurants offering discounts and giveaways as well, so check in with your nearby pizza joints, bakeries and the like.
Pi Day pizza deals
What’s better than pizza? Nothing. It’s the perfect food. You can even make it healthy(ish) if you’re weird and like to load it up with veggies. (Actually, I typically opt for light cheese and extra sauce, so I may be the weird one.) Here are the best Pi Day pizza deals I’ve found:
7-Eleven: Participating stores will be offering up large pizzas — cheese, pepperoni and “extreme meat” varieties — for $3.14 each. You can get this in-store or via the 7-Eleven app. 7-Eleven will also donate one meal to Feeding America for every whole pizza purchased on Pi Day.
Blaze Pizza: As in Pi Days past, the chain is offering any regular-size pizza for $3.14. You’ll need to download the Blaze Pizza app, create an account and access the deal in the Rewards section.
BJ’s Restaurant & Brewhouse: From now through Sunday, you can get half off a large pizza for takeout or delivery with the promo code HALFOFF.
Hungry Howie’s: Between March 13 and 16, you can get a $3.14 medium one-topping pizza with the purchase of Howie Bread.
Marco’s Pizza: Buy any large pizza at menu price and get a second one (of equal or lesser value) for only $3.14. Use promo code code PIDAY.
Papa John’s: Order one large pizza, get a second for $3.14.
Save A Lot: If you have one of these grocery stores nearby, stop in on March 14 for a Mantia frozen pizza for $3.14.
Your Pie: Get a 10-inch pizza for $3.14 off when you install the Your Pie Rewards app and redeem the Pi Day offer. 
Other Pi Day deals
Fresh Market’s pies (apple, cherry and chicken) will be $3.14 off for Pi Day.
Fresh Market
Turns out there are other kinds of pies: fruit, chicken pot and so on. (Also: smoothies?) These are some notable deals on them:
Boston Market: Buy one pot pie and a drink, get a second pot pie free. Also known as a BOGO, this deal requires you to use the Boston Market app. It’s good only on Pi Day. 
The Fresh Market: On March 14, you can save $3.14 on the store’s 9-inch apple and cherry pies and chicken pot pies.
Jamba Juice: It’s not a pizza or a pie, but from March 12-14, My Jamba Rewards members can get one small smoothie free with the purchase of a large one.
