"Triennial" refers to an event that occurs every three years. This term is often used in the context of art exhibitions, conferences, or festivals that take place on a three-year cycle. For example, the Venice Biennale is a famous art exhibition that showcases contemporary art from around the world, but it is held every two years, while a triennial would occur once every three years. In addition to art, triennial events can also be found in various fields such as education, business, and environmental studies. These gatherings allow participants to share knowledge, discuss advancements, and collaborate on projects that may take time to develop. By meeting every three years, attendees can reflect on progress and set new goals for the future.
