how often is mayor elected

Direct answer: The frequency with which a mayor is elected depends on the city and country. In the United States, mayoral term lengths are typically four years in many major municipalities, though some cities use two-year terms or have term limits that cap the number of terms a mayor can serve. There is wide variation: a handful of cities elect mayors for two-year terms, several use four-year terms, and a few have unique arrangements or dual-year cycles. Because different jurisdictions set their own terms and term-limit rules, there isn’t a single universal answer. If you specify the city or country you’re interested in, a precise term length and any term-limit rules for that mayoral office can be provided.
