(a) Computing time. In computing any period of time prescribed or allowed by order or directive of the agency, or by any applicable statute, unless otherwise specified, the period shall begin on the day after the act or event in controversy and conclude on the last day of such computed period, unless it be a Saturday, Sunday, or legal holiday, in which event the period runs until the end of the next business day which is neither a Saturday, Sunday, nor a legal holiday.
(b) Extension. Unless otherwise provided by statute, the time for filing any pleading, motion, or request may be extended by order of the executive director, upon written motion filed prior to the expiration of the applicable period of time for the filing of the same, showing that the need for extension is not caused by the neglect, indifference, or lack of diligence of the requesting party.
