How often did Scrooges clerk get paid for a day that he did not work and when in the book A Christmas Story?

In Charles Dickens' "A Christmas Carol," Bob Cratchit, Scrooge's clerk, is paid for a day he did not work on Christmas Day. Although he typically only receives a meager wage for his labor, Scrooge begrudgingly allows him to take Christmas Day off without docking his pay, reflecting the societal norms of the time where workers often had that day off for holiday celebrations.
