    Here is my code for those who need it.

    DynamicTimeSpan-Class:

    using System;
    using System.Text;
    
    namespace fooLib
    {
        /// 
        /// Timespan where you can define the number of hours a day can last (+ days of week).
        /// Optimal for calculating bussinesshours.
        /// 
        public class DynamicTimeSpan
        {
            private int _hoursPerDay = 8;
            private int _daysPerWeek = 5;
            private int _totalMinutes = 0;
    
            public int HoursPerDay
            {
                get { return _hoursPerDay; }
                set { _hoursPerDay = value; }
            }
    
            public int DaysPerWeek
            {
                get { return _daysPerWeek; }
                set { _daysPerWeek = value; }
            }
    
            public int Weeks
            {
                get
                {
                    return  (int)(((_totalMinutes / 60) / this.HoursPerDay) / this.DaysPerWeek);
                }
            }
    
            public int Days
            {
