I need an expression to get 5th last working day of the month.

Question

Is there any solution for this ?

My first inclination is that you can make use of the Workday() function . For this you would pass in the last day of the month, and "-5" for the number of work days to count from.

Seems like workday(date(ri!year, ri!month + 1, 01), -5) works when the first of the month after the one you're looking at is a work day. 
 When it's not a work day, workday(date( ri!year , ri!month + 1 , 01), -4) seems to do the trick. Something about it being counted when going backward or not counted. 
 You have the calisworkday() to to see if first of the following month is a workday, using year, month + 1, 1, and probably for best results noon. 
 so if( 
 calisworkday("first of the following month"), 
 workday("first of the following month" minus 5), 
 workday("first of the following month" minus 4) 
 ) 
 Let me know how that goes
