The electors of each township annually shall assemble and hold a township meeting in the month of March at the place in the township or in an adjacent township designated by the board of township supervisors. Notice of the time and place of holding the meeting must be given by the township clerk at least ten days before the meeting by publication in a legal newspaper published in the township or, if there is no such newspaper, then in the county’s official newspaper. Before a change in the place of holding the annual township meeting is made, notice of the contemplated change may be given by any member of the board of township supervisors to the township clerk, who shall have such change published if time allows. Otherwise, the township clerk shall post notice of the change. If an incorporated city is wholly or partially within the boundaries of the township or an adjacent township, all township meetings may be held at the place within an incorporated city designated by the board of township supervisors.
