Japan descends from China descends from Noah

The Japanese dates 3060bc Feb 2 and 660bc Feb 2 both come from Noah dying on Greek 10th month December 24 Christmas eve in the belief he was raptured to heaven because a spirit appeared to Babel priests for 40 days until the Egyptian date Thoth 24 (on Feb 2 in 2020bc) which in 388bc became Zoroastrian Christmas eve as the 10th month. Part of the Japanese reconstruction in 660bc to find Noah's Flood as 3060bc is by matching Feb 2 to Noah's date 3-27 which ended the 40-day rain.
However, their insisting 3-27 is Feb 2 is wrong. Though Japan is using 3-27 (as the true 3-27-600 on 2369bc Jan 6) thus disagreeing with China's 2952bc Jan 6 being 9-27 debating 2953bc July 10 on 3-27, their Japanese use of Feb 2 is wrong for the Flood's 40 days being stolen from Noah's rapture by himself at death instead of the rapture of all 8 people upward in the ark.
(Additional confusion occurs due to Ur's mass suicide to go to heaven on Koyak 24 which is May 5 in 2029bc. The solstice 4 months earlier was Mesor 24 on Jan 6. But the word Kayak /Kyak means oen-man boat. It's reference in 2029bc is to Peleg who die alone by himself on May 6 so that 365 days later Nahor Alumdug and Haran Meskalumdug committed suicide with their many wives via poison.) Noah died 8.5 years later in 2021bc.
