Problem with CountA - Calendar table - working day

[Arnaud81]

Hello everyone,

I am trying to have in a column "WorkingDay(Month)" the consildated number of working days for a particular month.
My calendar is 2 years (day level).

I have succeded so far to have the number of working days by month but with no distinction between years...so for example April has 43 working days.
I don't know how to fix this...

My calculated column formula :

= IF (
Calendar [WorkingDay] = "Y" ;
COUNTAX (
FILTER(
Calendar; Calendar[FiscalMonthNumber] = EARLIER (Calendar[FiscalMonthNumber];1)
)
;Calendar[WorkingDay]
)
)


Thank you for your help

Arnaud
