Congress Overwhelmingly Approves Juneteenth as New Federal Holiday

As a longtime fed employee, I’ll happily take off as many days as they give me, but I wonder if there will ever be a maximum as to how many fed holidays there are? Maybe if Congress adds a new one, they have to eliminate an old one…. Maybe combine Vet’s w/ Memorial? Or elim Columb (unless renamed for indigenous). Or add Juneteenth and cut MLK?
