In early January 2018, a mother and father started saving for a new apartment. They received their salaries on the 15th of each month, and each time the mother saved 12,000 rubles, while the father saved 22,000 rubles. At some point, the father's income decreased, and the family decided to spend all of his salary on current expenses and save only from the mother's salary. On October 11, 2020, it turned out that the mother's savings were twice as much as the father's savings. From which month and year did the father's salary go towards the family's current expenses? Indicate the month and year.
