While many of us will refer to March 14 as Tuesday -- Taco Tuesday even -- math and numbers enthusiasts will soak up the day known to them as "Pi" Day.
That is the two-letter Pi, the mathematical value of 3.14..., not the delicious dessert devoured during the holidays. An easy mistake to make, though not as tasty.
To celebrate, some businesses are taking advantage of the opportunity to offer guests a prime deal.
We've gathered a few of them below. As more come into the newsroom, we will update.
