How often does a biennial event take place?

• Once every two years:The term "biennial" is used as an adjective in the English language, but can also be used as a noun. As an adjective, it describes something that takes place every other year, or once every two years. As a noun, it implies an event that occurs or is celebrated every two years, or a plant that blooms once every other year. Biennial is often used interchangeably with biannual but the two terms actually have different meanings. Biannual means something takes place twice per year. A solstice, for example, is a biannual event. The Olympic games are biennial, with the summer games taking place one year, and the winter games following two years later. In another two years, the summer games come around again. Source: Grammar.com
