Pi Day, observed annually on March 14th (written as 3/14 in the US date format), is a celebration of the mathematical constant pi (π), which represents the ratio of a circle’s circumference to its diameter. The date corresponds to the first three digits of pi, 3.14. While rooted in mathematics, the day has evolved into a significant marketing event for food retailers, capitalising on the phonetic similarity between "pi" and "pie" and the circular nature of pizzas and pies.
According to the provided documentation, Pi Day 2025 falls on a Friday.

These offers generally require specific actions, such as joining loyalty programmes, using promo codes, or making a purchase.
