The significance of this day

And it was said that all the day signs were good all thirteen. And Two Rain, and Three Flower, Four Crocodile, Five Wind, Six House, Seven Lizard, Eight Serpent, Nine Death, Ten Deer, Eleven Rabbit, Twelve Water, Thirteen Dog ?all, in truth all, were as hath been told in their account. All went to be considered and were observed as of, and they followed, the same pattern. They were only one, regarded as only one in their relation and account, as they went in order there day by day, each one of the days in its proper place, so proceeding in order, one, two, three, henceforth until they reached and completed the end of the day count, thirteen.
