biyearly
Every six months
Biyearly suffers from the same ambiguity as biweekly and bimonthly—it can mean either twice a year or every two years.
Context usually clarifies: biyearly dental checkups suggests twice yearly, while biyearly elections likely means every other year.
When precision matters, use semiannual for twice yearly or biennial for every two years.
