Ancient farmers watched the moon's cycles change at regular intervals every 29 or 30 days, and they followed the moon to predict their crop growing seasons. Later, they used the sun because it told them when the rains would come and when the snows would melt. People on Easter Island built stone monuments to forecast dates, while Egyptians drew calendars on papyrus. After Johann Gutenberg invented his printing press, we printed our calendars. Our affairs are controlled by those billions of pieces of paper called calendars. We schedule our lives based on the calendar.
