Hi All,

Can you please help and show how to list all workdays for a month as shown in the example
The dates for each month in the top row should pick up from the last date of the previous month.

I assume this would be a SEQUENCE formula with EOMONTH in cells C4, F4, I4 etc, but I am stuck.
This would also be nice to have if the list of holidays shown in the image were omitted. These are referenced in a Holidays Tab from Cell A1:C8

You can consider or ignore the following. I initially had trouble getting both Jan and May to show correct answers and then was side tracked.
I didn't notice that Fluff had provided a solution that works.

N.B.
Ensure that your holiday list is for 2024.

Test the following
with Name Manager
Name the function to a name that you prefer; I named it ListWorkdaysMo
The function shows the parameters required Year, Month (full name or 3 letters), and holidays.
Value
=LAMBDA(Year,Month,Holidays,LET(y,Year,m,Month,h,Holidays,d,DATE(y,MONTH(--1&LEFT(m,3)),1),n,WORKDAY.INTL(d-1,SEQUENCE(24),1,h),IF(MONTH(n)=MONTH(d),n,"")))
