A. A bank is authorized to fix from time to time the days and hours when each of its banking offices that are located in this state will be open to the public for its banking business. The days and hours need not be the same for each office. The bank shall notify the superintendent of the days and hours of each banking office and of any change in the scheduled days and hours of each office. The bank shall give further notice by whatever means it selects as best calculated to advise the public of any change.
B. In an emergency or threat of an emergency or other circumstances beyond the control of the bank which would imperil persons or property or impede normal operations, all or any of its banking offices that are located in this state may be or remain closed. Notice of the closing shall be given to the superintendent as promptly as conditions will permit. The superintendent may order the reopening of any office on his finding that conditions justifying the closing under this subsection do not then exist.
C. Any day on which a bank shall pursuant to this section be or remain closed shall with respect to the bank be deemed a legal holiday.
D. Any office of a bank may be closed under subsection A or B, even though other offices of the bank are open, but any day of such closing shall not be a legal holiday in respect to any acts to be performed by or at the bank on such day unless the act is to be performed only by or at the office which is closed.
E. Where pursuant to agreement or law any act is to be performed by or at a bank on any day when such bank shall pursuant to this section be or remain closed, the act may be performed on the next succeeding banking day with the effect as though performed on the appointed day.
F. Nothing in any law of this state shall in any manner whatsoever affect the validity of or render void or voidable the payment, satisfaction or acceptance of any check or other negotiable instrument or any other transaction by a bank because done or performed on any holiday or partial holiday or during any time other than regular banking hours, but nothing in this subsection shall be construed to compel a bank to perform any of the acts or transactions aforesaid except at its own option.
