What does semiannually mean?
Semiannually is an adverb meaning twice a year, or once every six months. It is frequently used in formal and professional settings to describe recurring reports, payments, meetings, reviews, and publications. For example, a company may issue financial results semiannually or conduct employee performance reviews at half-yearly intervals.
