For purposes of calculating any period of time under this part, the period begins to run on the day following the day that a communication is received or an act is completed. If the last day of the period is a Federal, State, or local holiday or a non-business day for one of the parties or the arbitrator, the period runs until the end of the first business day that follows. Holidays or non-business days occurring during the running of the period of time are included in calculating the period.
