Celebrated annually on February 9, Pizza Day recognizes thin crust, Chicago-style, deep dish, and every other incarnation of the national dish of Italy.

Observed primarily in the United States, where pizza is a favorite food, this food holiday is dedicated to enjoying and promoting pizza.

Approximately 3 billion pizzas are sold in America each year, which averages to about 46 slices or 23 pounds of pizza per person annually.

On this day discounted pizzas can be found at many restaurants, pizzerias, and food outlets.
