Formula to determine the number of work hours per month
 

I am trying to figure out the summary of work hours for a month. The problem is that we work 24hrs on Mon to Thu and on Fridays we only work 8hrs.
Therefore a short month will have less hours than a long month and a month with more Fridays will have less hours than other months.

Please help me with a formula which determines the number of work hours per month as
per above schedule.

I have named a certain cell "Month_no". The number in the cell is changing according to a macro. The formula should refer to the name: Month_no and determine the number of hours for that specific month.

Thanks for helping

the number of the month in A1.
Then try:

=SUMPRODUCT((WEEKDAY(ROW(INDIRECT(DATE(2021,A1,1)& ":"&EOMONTH(DATE(2021,A1,1),0))),2)<5)*24)+SUMPROD UCT((WEEKDAY(ROW(INDIRECT(DATE(2021,A1,1)&":"&EOMO NTH(DATE(2021,A1,1),0))),2)=5)*8)
