Filtering with Calender

I’d like to use the Calender and Filter the Days that I can make an event on.

I understand I can Make a collection of Holidays and filter those out, but how can I do a larger filter to exclude saturday and Sundays (weekends)?

is there a setting I am missing?

I should be able to filter by using the operators not equal to “saturdays, sundays” but there is no way to select all saturdays or sundays, that i can see
