In the world of Binance, the term primarily refers to the celebration of "Bitcoin Pizza Day." This day falls on May 22 each year and commemorates the first real-world purchase using Bitcoin, where a programmer named Laszlo Hanyecz bought two pizzas for 10,000 Bitcoins in 2010.

Although the original purchase did not occur on the Binance platform (which was established later), Binance and the broader cryptocurrency community celebrate this day as it marks an important historical moment in the evolution of the use of cryptocurrencies in the real world.
