The various astronomical days, months and years really do exist; but the calendrical day and month and year do not. They are creations of the calendar, which approximate the astronomical periods in some ways. But they aren't just inaccurate measurements; to use the astronomical units would be wrong by the calendar. So these units have no existence without the calendar. -- SJK
