2.  Each local school district may set its opening date each year, which date shall be no earlier than fourteen calendar days prior to the first Monday in September.  No public school district shall select an earlier start date unless, for calendars for school years before school year 2020-21, the district follows the procedure set forth in subsection 3 of this section.  The procedure set forth in subsection 3 of this section shall be unavailable to school districts in preparing their calendars for school year 2020-21 and for subsequent years.

3.  For calendars for school years before school year 2020-21, a district may set an opening date that is more than fourteen calendar days prior to the first Monday in September only if the local school board first gives public notice of a public meeting to discuss the proposal of opening school on a date more than fourteen days prior to the first Monday in September, and the local school board holds said meeting and, at the same public meeting, a majority of the board votes to allow an earlier opening date.  If all of the previous conditions are met, the district may set its opening date more than fourteen calendar days prior to the first Monday in September.  The condition provided in this subsection must be satisfied by the local school board each year that the board proposes an opening date more than fourteen days before the first Monday in September.
