Did you order pizza for lunch today? Good choice! Whether you knew it or not, your meal choice was spot on—what better way to celebrate National Pizza Day than by enjoying a delicious slice? Every year on February 9, pizza lovers around the world come together (often unknowingly) to pay tribute to one of the most beloved dishes of all time.
The origins of this tasty holiday remain unclear, even to the most dedicated pizza enthusiasts. But according to one well-known search engine, this unofficial celebration gained momentum in the second half of the 20th century, when pizza became wildly popular in the U.S. and beyond. Some believe it took shape in the 1970s and 1980s, as restaurants and fast-food chains began promoting national food days as part of their marketing strategies.
But why stop at just one pizza holiday? Thanks to clever marketing—and the undeniable appeal of pizza—you can enjoy multiple pizza-themed celebrations throughout the year. Here are two other dates to mark on your food calendar:
- September 5: Celebrate Pizza Margherita Day in Italy, honoring the classic Neapolitan pizza that stole Queen Margherita’s heart.
- January 17: World Pizza Day—this day commemorates UNESCO’s 2017 recognition of “the art of Neapolitan pizza makers” as an Intangible Cultural Heritage of Humanity. The date coincides with the Feast of St. Anthony Abbot, the patron saint of bakers and pizza makers.
About today’s guest of honor—pizza—you could talk for hours, debate its flavors and sizes. But one thing is undeniable: pizza is a reliable, time-tested, and beloved companion of millions of travelers. You’re guaranteed to find it in every corner of the world, and no matter what name it goes by—Margherita, Pepperoni, or Marinara—it will never let you down.
