The World Expo is held every five years. It typically lasts for about six months and serves as a global platform where countries showcase their latest innovations, ideas, and solutions around a common theme. For example, the upcoming Expo 2025 will be held in Osaka, Japan, from April to October 2025, following the traditional five-year cycle after the delayed 2020 Expo in Dubai. This frequency has been consistent since 1995 as regulated by the Bureau International des Expositions (BIE).
