By the first day of the Noah's next year the earth was completely dry. November 30, 1991, the financial reserves of the Soviet Union are exhausted, and the Soviet Union warns of bankruptcy. The Duma would reject printing money to prevent inflation, handling the government to Yeltsin and Russia. Yeltsin agrees to fund the Soviet Union effectly taking over the collapse.
On the first day of the first month of Noah's 601st year the earth was completely dry. That date maps to Saturday, November 30, 1991.
On the Friday before the Soviets had hinted that they had enough money for maybe two more days of operation. At that point they would be out of funds. Empty. Dry. The Soviet Union was about to screech to a halt.
On Saturday, November 30, 1991, Yeltsin, the leader of the Russian Republic, announced that they would assume all financial obligations of the Soviet Union and take over all financial institutions. The hand-off was complete by the start of business on Monday.
To add insult to injury the Ukraine, who had voted a transitional form of independence the previous August now voted on December 1, 1991, for full independence. By December 2, 1991, Yeltsin had recognized the Ukraine's independence from the Soviet Union.
By December 26, 1991, the Soviet Union formally voted to disband.
The trunk day-for-a-year timeline puts the last year of Noah's life in a year that maps to Sunday, January 5, 1991. A date we look at next.
