Why sleep is so good for your memory



Calendar structure

📆When it’s about the calendar the biggest thing that baffles me is, how is a said year continued and not completed. In instance 2014 is followed by 2015. Why isn’t it these years would comple themselves? 2013(2013complete year)2014(complete year)2015
Thinking it out it makes more sense to not call a half rotation a whole
