The merging of event horizons of binary black holes is investigated. Although the recent development of the numerical study of binary black hole coalescence has shown that their apparent horizons can orbit for many periods, we study the orbital motion of event horizons. We discuss how many periods the event horizons of binary black holes orbit before their coalescence. We find that they soon merge into one horizon and that black holes cannot orbit for half a period, while apparent horizons can orbit many times.
