Computation of time.

§ 16.27 Computation of time. (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.
