It appears from the previous post that really there are 9 days of Creation. The extra three days are in the second group of eight hours, namely the first, the third, and the eigth hour. The tenth day is the day of 24 hours itself. This is Shabbat. It includes all, just like Keter includes all.
In the days of the week of Creation, as referred to by Chazal, the first three days are overloaded. The first day is also the fourth, the second also the fifth, the third also the sixth. This way, the time of Torah, the third and fourth day, in the second reading of the "third day", started in the year 2084. For completeness let it be mentioned that the years of Moshiach started with the fifth day, in 5332.
The hours 4 through 7 of each of the three periods of 8 hours, represent stages of growth, evolution. Hour 4 to 7 has the evolution of species until the advent of hominids, hour 12 to 15 has various stages of the growth of mankind until the advent of the time of Torah, and, finally, hour 20 to 23 has the Aliyot, the stages of Jewish settlement of the Land of Israel, starting with the Aliyah of Talmidei HaG"ra.
P.S. A great resource for studying the evolution of mankind. The enormity of it makes one silent.
