        (a) 
         In computing any period of time under this
 part or in an order issued thereunder, the time
 begins with the day following the act, event, or
 default, and includes the last day of the period,
 unless it is a Saturday, Sunday, or legal holiday
 observed by the Federal Government, in which event
 it includes the next business day.
     
    
        
        (b) 
         When the period of time allowed is less
 than seven days, intermediate Saturdays, Sundays,
 and legal holidays observed by the Federal
 Government shall be excluded from the computation.
 When the period of time allowed is more than seven
 days, all intervening calendar days are included
 in the computation.
     
    
        
        (c) 
         Where a document has been served or issued
 by mail, an additional five days will be added to
 the time permitted for any response.
