(b) The last day of the period being computed shall be included, unless it is a Saturday, Sunday, or a legal holiday, in which event the period runs to the end of the next day which is not a Saturday, a Sunday, or a legal holiday. (c) When the period of time prescribed or allowed is less than seven days, intermediate Saturdays, Sundays, and legal holidays shall be excluded from the computation. (d) A legal holiday for the purposes of 804 CMR 1.17(1)(b) includes those days specified by M.G.L. c. 4, § 7 and any other day appointed as a holiday by the President or the Congress of the United States, or designated by the Laws of Massachusetts. (2) Extensions. (a) Pre-probable Cause. During any stage of the investigation, upon written request and for good cause shown, any party may request an extension of time. The request shall be addressed to the Commission and state the extension of time being requested and the reason(s) for the extension. (b) Post-probable Cause. After an investigative disposition has issued, any request for an extension shall be made to the Clerk's Office and shall be subject to motion practice and other requirements within 804 CMR 1.13.
