I assume this is a calendar table with rows on the day? And you want to specifically mark each 7th day of the working month? 
You could do something like this: 
Create 1 calculated column that is a Year-Month column. If you're in fiscal periods, you can even make this a number format such as "202401" which is 'Calendar Table'[Fiscal Year] & FORMAT('Calendar Table'[Period],"00")
Or if it's just a regular calendar table, just do something like: 
Year Month = 
YEAR('Calendar Table'[Day]) & " - " & MONTH('Calendar Table'[Day)

So now that you have the 'year - month' column create one or two more columns, depending on how you want to do it. You could create a column that marks whether each row is a weekend and then count that. Doing something like = 
Working Day = 
VAR weekDay = WEEKDAY('Calendar Table'[Day])
VAR weekend = weekDay = 1 || weekDay = 6
RETURN
NOT weekend

You might also want to work off a holiday calendar and you can add additional logic for holidays. 
But the other way which might be simpler to return your one issue is just: 

7th Working Day = 
VAR curYearMonth = 'Calendar Table'[Year Month]
VAR startMonth = 
MINX(
    FILTER(
       'Calendar Table'[Year Month] = curYearMonth
    ),
    'Calendar Table'[Day]
)
VAR curDay = 'Calendar Table'[Day]
VAR curWorkDays = NETWORKDAYS(startMonth,curDay)
RETURN
curWorkDays = 7

Hi , Thank you, I need 7th working day of next month. For example I have column of month and if month is Jan'24, then I need 7th working day of Feb'24 (excluding weekends and if any holiday list i have). Itried below but still it is not giving exact 7th working day for all the months. I think I am missing something,

Hi,

Here is one way to do this:

7th workday =
var _year = [Year]
var _month = MONTH([Date])
RETURN

CALCULATE(MAX([Date]),
FILTER('Calendar',
NETWORKDAYS(STARTOFMONTH('Calendar'[Date]),[Date])=7
&&'Calendar'[Year]=_year && MONTH('Calendar'[Date])=_month
))

End result:
