March 14 is Pi Day, which is the celebration of the mathematical sign Pi, selected because the numerical date of 3.14 represents the first three digits of Pi. The date has obvious importance to engineers and scientists because the unit of measurement has obvious significance for mathematical calculations and in understanding many phenomena in the physical world.

it is safe to say the average person is either unaware of or attaches no meaning to Pi Day. It is not a day off or national holiday. However, the food business is increasingly taking a vested interest in Pi Day, offering discounts on (of course) pies and some other food items. While their interest is undoubtedly propping up their bottom line on an otherwise uneventful day in March, any promotion to get people even the least bit curious on the meaning of Pi Day cannot hurt.

The site of Good Housekeepingꟷa venerable brand long known for dispensing sound advice on maintaining a householdꟷhas gotten into the action on Pi Day, coming up with lots of delicious suggestions in an article titled, “The Best Pi Day Deals and Freebies of 2023 on Pizza, Pies, and More.” For busy engineers slaving away on their designs, we have listed many of the discounts and deals from the article below, complete with links to the companies’ websites. Remember, many of these companies have apps that enable one to order from their smartphones.

You can now ponder the meaning of Pi Day while you devour a slice of pizza.
