Hello,

I am looking for a function that would allow me to know the number of a given day of the week in a month.
Assuming that this function is: NbJSMois
and that we had the days of the week as follows:
Monday = 1, Tuesday = 2, ..., Sunday = 7

Eg. NBJSMois (4, 1, 2009) = 5

There are 5 Thursdays in effect in January 2009.

Thank you for any response.
