When did Zhuge Liang borrow Dongfeng?

So on the 2th of November, Kong Ming took a bath and fasted, was clothed in Taoist clothes, and let out his feet, and went up to the altar to start offering sacrifices to the wind. Kongming went to the altar three times a day and went down three times, but there was no southeast wind. It was late at night, and the sky was bright and the breeze did not move. Until nearly midnight, I suddenly heard the wind and the flags were turning. When Zhou Yu went out to look at the account, the flag was floating in the northwest. At the moment, the southeast wind is strong. After the southeast wind rose, Zhuge Liang had already come down to the river, left Zhou Yu's camp in the boat that Zhao Yun came to meet, and went back to Xiakou where Liu Bei was.

The time-keeping method with the combination of branches and branches was invented by China people, and it is in hexadecimal. Therefore, "Jiazi" year cycles once every 6 years. "Jiazi" month cycles once every five years (6 months). "Jiazi" Day circulates every 2 months (6 days). The "Jiazi" hour circulates every five days (6 hours X 2 hours/hour). So as long as you remember the latest year, month, day and time of Jiazi, you can calculate all the time.

For example:

: on January 1, 198 (Gregorian calendar) =

(Lunar calendar) On the fourteenth day of November, the eight characters: I have not been married to my son (that is, the representation of trunk and branch timing)

Then you can press the previous year, the next year, the last few months, the next few months and so on.

the calculation table is as follows:
