when the law states 'within 20 days' is that within 20 days or business days
Under the rules of civil procedure you start count days the day after the paper was filed. So if it was the paper was filed Nov. 1st. day 1 is November 2nd. If the 20th day is a weekend or court holiday you get until the day following the weekend or holiday. It's covered under rule 106 of the Pennsylvania Rules of Civil Procedure.
