In computing any period of time specified in this chapter, the day of the act, event, or default shall not be counted, and the last day of the period shall be counted unless it is a Saturday, Sunday, or legal holiday, in which event the time period shall continue until the next day that is not a Saturday, Sunday, or legal holiday.
An ALJ may waive any of the prescribed time periods established in this chapter or the Act, if the respondent requests a waiver in writing within one year of the date of service of the infraction, and shows to the satisfaction of the ALJ why the time period should be waived.
