Computation of time: acts due on a closed court or office are timely if done the next open day, subject to limitation exclusion. Where a Central Act or Regulation requires an act or proceeding to be done on a certain day or within a prescribed period, performance on the next day the court or office is open is treated as timely if the court or office was closed on the required day or the last day of the prescribed period; this does not apply to acts governed by the Indian Limitation Act, 1877, and applies to Central Acts and Regulations made on or after the specified January 1887 date.
