What is bi annual?

The term "biannual" can be confusing because it is used to mean two different things, depending on the context. Here are the two primary interpretations:

1. Twice a Year: In this interpretation, "biannual" refers to something that occurs twice in one calendar year, such as a biannual meeting or publication. Events or publications that happen biannually might occur every six months.

2. Every Two Years: Some use "biannual" to mean once every two years. However, to avoid confusion with the first meaning, this is more commonly referred to as "biennial."

To ensure clarity, it is often better to use the terms "semiannual" for twice a year and "biennial" for every two years. This avoids misunderstanding and communicates the intended frequency more accurately.
