>>I am trying your approach. I don't quite understand the resulting "image" your code creates though.

>>But I was thinking last night, after I turned off the computer. Maybe there is a simpler way to do what I need to do. Let me describe what this code is suppose to do. The code sets the Target Date based on the Current Date and the Days2Advance (the number of days that should be given for the job). Some customers consider Saturday non working day and therefore, skip it. Others consider Sunday a non working day and skip it. And then others consider both Saturday and Sunday as non working days.
>>I could simply create a loop and advance the date from current date, adding 1 day in the loop (until Days2Advance is reached). And in the loop, on every advance check the Day of the Week and if it is Saturday/Sunday, do not add it to the Days2Advance.
>>
>>But I am still curious how your formula works but I will change the code to real dates and create to FOR: one iterating the Today's day, say from Jan 1, 2017 to March 1, 2017. Then, within this FOR I will change the DaysToAdvance from 1 to 20 (very reasonable range). And then, using your formula, calculate the Target/End date. And if it is NOT Saturday or Sunday, the formula works. Does it make sense?
>>
>>UPDATE: Unfortunately when I run my code with real dates, many ending dates fall on either Saturday or Sunday. Don't waste your time on my problem. I will try the LOOP approach that I described above.

>The visualization code loops through different DaysToAdvance just to demonstrate that the calculation of real days to advance (this is just one line of code) is getting a pair of extra days for each weekend it encounters (that is, trying with 1 day to advance, then with 2, and so on). In the visual list, the dot is the starting day, each + represents a business day that was advanced, and each | a weekend day (Sat. or Sun.). So, each iteration must end with a + (that is, a business day), and in my runs that occurs no matter which DaysToAdvance, and no matter which TodayDow (from 1 to 5).

>Can you give an example of a situation for a real date for which some advance of days falls on the weekend? Don't worry, it's an academic interest... What is important is that you have a working solution (I think that going through a loop is a sensible solution, considering your full requirements and also the questions that Dragan pointed out).

This is the code I used to apply your formula:

I starting with the first day of this year and scan 40 days. Then scan through up to 20 advance days. If the resulting date falls on Saturday or Sunday, show the message. Let me know if you see anything I missed.

dStartDate = CTOD('12/31/2016')
FOR i = 1 TO 40
	dStartDate = dStartDate + i
	
	FOR nDays2Advance = 1 TO 20 
		m.TodayDow = DOW(dStartDate)
		m.RealDaysToAdvance = m.nDays2Advance + INT((m.TodayDow + m.nDays2Advance - 1) / 5) * 2	
		dEndDate = dStartDate + m.RealDaysToAdvance
		IF DOW(dEndDate) = 1 OR DOW(dEndDate) = 7
			MESSAGEBOX("Wrong day. " + " Start Date: " + DTOC(dStartDate) + ;
			" Days to Advance " + ALLTRIM(STR(m.nDays2Advance)) + "  Real days to advance: " + ALLTRIM(STR(m.RealDaysToAdvance)) + CHR(13) + ;
			"End Date: " + DTOC(dEndDate) + " which is " + ALLTRIM(STR(DOW(dEndDate))))
                ENDIF
	ENDFOR 

ENDFOR
