I don't believe that "6 hours a day" is an answer any historian would give when asked how much workers in any period in history worked.
There have been indications that there were approximately 150 days per year which were most active for medieval farmers, but if I had a time machine I wouldn't stay there very long if my desire was to experience good working conditions.
