Answer 2

"(salary / (working days of month)) * (working days of last week)" Above line should be your formula for calculating last week salary. So, you need a method which calculates working days of given date interval.

function getWorkingDays(startDate, endDate){
    var totalWorkingDays= 0;
    var currentDate = startDate;
    while (currentDate <= endDate)  {
        var weekDay = currentDate.getDay();
        if(weekDay != 0 && weekDay != 6) {
            totalWorkingDays++;
        }
        currentDate.setDate(currentDate.getDate()+1); 
    }
    return totalWorkingDays;
}

Then, give the dates and apply the formula.

I have used below code in Jaggeryjs and working fine for me. I haven't tested yet but getting expected result.

 var currentDate = new Date();
    var requiredDate;
    log.info(currentDate)
    var set=currentDate.setHours(0)
    if(currentDate.getDay() == 1)
    {
     requiredDate=new Date(currentDate.getFullYear(),currentDate.getMonth(),currentDate.getDate()-7)
    }
    else if(currentDate.getDay() == 2)
    {
     requiredDate=new Date(currentDate.getFullYear(),currentDate.getMonth(),currentDate.getDate()-8)
    }
    else if(currentDate.getDay() == 3)
    {
     requiredDate=new Date(currentDate.getFullYear(),currentDate.getMonth(),currentDate.getDate()-9)
    }
    else if(currentDate.getDay() == 4)
    {
     requiredDate=new Date(currentDate.getFullYear(),currentDate.getMonth(),currentDate.getDate()-10)
    }
    else if(currentDate.getDay() == 5)
    {
     requiredDate=new Date(currentDate.getFullYear(),currentDate.getMonth(),currentDate.getDate()-4)
    }
    else if(currentDate.getDay() == 6)
    {
     requiredDate=new Date(currentDate.getFullYear(),currentDate.getMonth(),currentDate.getDate()-5)
    }
    else if(currentDate.getDay() == 7)
    {
     requiredDate=new Date(currentDate.getFullYear(),currentDate.getMonth(),currentDate.getDate()-6)
    }
    var start=Date.parse(requiredDate)
    log.info("Start-Date["+start+"]")         
    log.info("End----------------------------------------------")
    var currentDate = new Date();
    log.info(currentDate)       
    var end;
    if(currentDate.getDay() == 7)
    {
     end=new Date(currentDate.getFullYear(),currentDate.getMonth(),currentDate.getDate()-2)
    }
    else if(currentDate.getDay() == 6)
    {
     end=new Date(currentDate.getFullYear(),currentDate.getMonth(),currentDate.getDate()-1)
    }

    else if(currentDate.getDay() == 5)
    {
     end=Date.parse(currentDate)
     log.info("End Date ["+end+"]")
    }
    else if(currentDate.getDay() == 4)
    {
     end=new Date(currentDate.getFullYear(),currentDate.getMonth(),currentDate.getDate()-6)
    }
    else if(currentDate.getDay() == 3)
    {
     end=new Date(currentDate.getFullYear(),currentDate.getMonth(),currentDate.getDate()-5)
    }
    else if(currentDate.getDay() == 2)
    {
     end=new Date(currentDate.getFullYear(),currentDate.getMonth(),currentDate.getDate()-4)
    }
    else if(currentDate.getDay() == 1)
    {
     end=new Date(currentDate.getFullYear(),currentDate.getMonth(),currentDate.getDate()-3)
    }


    end=Date.parse(currentDate);
    log.info("End-Date["+end+"]")         
    query="taskCreateTimestamp:["+start+" TO "+end+"]";
