International Pillow Fight Day is celebrated worldwide on the first Saturday in April. The holiday originated with its first event on March 22, 2008, featuring coordinated pillow fights in 25 cities globally, including a notable participation of over 5,000 people in New York City. Initially presented as a fun communal activity rather than a competition, the event has evolved into an organized celebration for people of all ages. Participants engage in playful pillow fights using soft, lightweight pillows, adhering to safety guidelines to ensure a fun experience. Although events were canceled in 2020 due to the COVID-19 pandemic and the official website has since gone offline, individuals can still celebrate by hosting their own pillow fights. Organizations such as the Pillow Fight Championship (PFC) and previous events by the Pillow Fight League (PFL) have contributed to the popularity of this quirky holiday.
