I think the code above run every 15 minute , you have SPMinuteSchedule , you must use SPDailySchedule . See msdn documentation

However when Job run you can get the current DayOfWeek and run your code when you want

        switch (DateTime.Now.DayOfWeek)
        {
            case DayOfWeek.Friday:
                break;
            case DayOfWeek.Monday:
                break;
            case DayOfWeek.Saturday:
                break;
            case DayOfWeek.Sunday:
                break;
            case DayOfWeek.Thursday:
                break;
            case DayOfWeek.Tuesday:
                break;
            case DayOfWeek.Wednesday:
                break;
            default:
                break;
        }

Or you can save inside Job Property Bag the last run. At this link you can find an example for SPWeb but is the same for SPJob.
