no is the abbreviation of which month?

The abbreviation of November.

November is the 11th month of the year. Its English name is November. It is located between October and December. The eleventh month of the lunar calendar is called the winter month.

Every year between November 7 and 8 in the Gregorian calendar, that is, when the sun is at 225° of ecliptic longitude, the northern hemisphere receives less and less solar radiation, because at this time there is still a certain amount of heat stored on the surface in the summer half of the year. There is leftover, so it’s generally not too cold. When the weather is clear and windless, there is often warm and comfortable "Indian Spring" weather, which is not only very pleasant, but also very beneficial to the growth of winter crops.

Origin of the name:

The Roman emperors Augustus and Caesar both had months named after themselves. The Roman citizens and the Senate asked the then Roman Emperor Tiberius to use The month of November is named after it. But Tiberius did not agree. He wisely told everyone that if every emperor in Rome named the month after his own name, what would happen if the 13th emperor appeared?

As a result, November still retains its old name Novem, which means "9" in Latin. This month was originally the ninth month in the old calendar. The English November evolved from this. It is also called the Winter Moon, Frost Moon, and Frost Moon.
