Word Nuance & Usage
Because "biweekly" can mean either "every two weeks" or "twice a week," it is notoriously ambiguous in formal and business contexts; to ensure clarity, many writers prefer using "every two weeks" (or "fortnightly" in British English) for the former and "semiweekly" or "twice a week" for the latter.
