Pi Day, celebrated annually on March 14 (3/14), is a math-inspired holiday that has been widely adopted by the food and retail industries to offer promotional deals. While the day honors the mathematical constant π, approximately 3.14, it has become an occasion for restaurants and brands to offer discounts, special pricing, and free items, particularly on circular foods like pizza pies and dessert pies. For U.S. consumers, deal seekers, and food enthusiasts, Pi Day represents an opportunity to access limited-time offers from a variety of national and regional chains. The following article details the specific promotions, eligibility requirements, and redemption processes for Pi Day offers based on available information from 2024 and 2025.
