Section 206-A. Business in county offices on holidays and Saturdays

1.
  Notwithstanding the provisions of any general or special  law,  holidays
  and Saturdays shall be considered as Sunday for all purposes relating to
  the  transaction  of  business  in county offices in every county of the
  state, except in a county wholly contained within a city.  On all  other
  days,   except  Sundays,  such  offices  shall  be  kept  open  for  the

  which are paid in whole or in part from county funds.
    2. Whenever the last day on which any paper shall be filed or act done
  or performed in any such office  expires  on  Saturday,  Sunday,  public
  holiday  or  a  day  when  such  office is closed for the transaction of
  business, the time therefor is hereby extended to and including the next
  business day such office is open for the transaction of business.
    3. Notwithstanding the foregoing provisions of this section, the motor
  vehicle section of a county clerk's office may,  by  resolution  of  the
  board  of  supervisors,  be  kept  open on Saturdays during the month of
  January.
