(a) Computing Time. Rules 6(a) and, except for electronically served documents, 6(c) of the Arizona Rules of Civil Procedure govern the computation of any time period set by these Rules, a court order, or an applicable statute.

(b) Modifying Deadlines. A party wishing to modify a deadline in the appellate court must obtain an appellate court order authorizing a modified deadline. An appellate court for good cause may shorten or extend the time for doing any act required by these Rules, a court order, or an applicable statute. But neither an appellate court nor a superior court may extend the time for filing a notice of appeal, except as provided by Rule 9(f).
