November

November is the eleventh month of the Gregorian calendar and has 30 days. Its name derives from the Latin novem, meaning "nine," reflecting its origin as the ninth month in the early Roman calendar before calendar reforms added January and February. With the reform, November moved to the eleventh position but kept its name.

In the Northern Hemisphere, November marks late autumn, characterized by cooling temperatures and falling leaves; in the Southern Hemisphere, it is late spring as days lengthen and flowers emerge.

The month hosts several holidays and observances. All Saints' Day on November 1 and All Souls' Day on November 2 are observed in many Christian traditions. Remembrance Day or Armistice Day is observed on November 11, to honor those who died in war; Veterans Day is the U.S. counterpart. Thanksgiving is celebrated in the United States on the fourth Thursday of November; Canada observes Thanksgiving earlier, in October. Other observances include Guy Fawkes Night on November 5 in the United Kingdom, and Movember, a global charity campaign held during the month to raise awareness of men's health. In many cultures, the beginning of November also features the Day of the Dead celebrations in parts of Latin America.

Among astronomical events, the Leonid meteor shower often peaks in mid-November, drawing interest from observers in both hemispheres. The Sun moves from Scorpio into Sagittarius during the month, signaling late autumn in the north and late spring in the south.
