March 14 is more than just another date on the calendar. Each year the day—written as 3/14—turns into a nationwide celebration of Pi Day, inspiring restaurants and grocery stores to introduce special promotions on pizza and dessert pies.
For Pi Day 2026, several major restaurant chains and food retailers are marking the occasion with discounts tied to the famous mathematical number π (3.14). From $3.14 pizza deals to buy-one-get-one offers, the annual celebration has become a popular opportunity for customers to enjoy their favorite comfort foods at lower prices.
Pi represents the ratio between a circle’s circumference and its diameter, and the first digits—3.14—are why March 14 has become the official day to celebrate it. The date also carries a historical coincidence: physicist Albert Einstein was born on March 14, 1879, adding another scientific connection to the celebration.
