The regular town election shall be held on the first Tuesday following the first Monday in November in each odd-numbered year.
A preliminary election for the purpose of nominating mayoral candidates shall be held on the third Tuesday in September in every other odd-numbered year, but the town clerk may, with the approval of the town council, reschedule this election to the fourth Tuesday to avoid a conflict with any civil or religious holiday. Whenever a special election to fill a vacancy in the office of mayor is to be held, a preliminary election shall be conducted 35 days preceding the date established for the special election.
