October is the tenth month of the year in the Julian and Gregorian calendars. Its length is 31 days. The eighth month in the old calendar of Romulus c. 750 BC, October retained its name (from Latin and Greek ôctō meaning "eight") after January and February were inserted into the calendar that had originally been created by the Romans. In Ancient Rome, one of three Mundus patet would take place on October 5, Meditrinalia October 11, Augustalia on October 12, October Horse on October 15, and Armilustrium on October 19. These dates do not correspond to the modern Gregorian calendar. Among the Anglo-Saxons, it was known as Winterfylleth (Ƿinterfylleþ), because at this full moon, winter was supposed to begin. [1]
October is commonly associated with the season of autumn in parts of the Northern Hemisphere, and spring in parts of the Southern Hemisphere, where it is the seasonal equivalent to April in the Northern Hemisphere and vice versa.
October's birthstones are the tourmaline and opal. [2] Its birth flower is the calendula. [3] The zodiac signs are Libra (until October 22) and Scorpio (from October 23 onward). [4] [5]

(All Baha'i, Islamic, and Jewish observances begin at the sundown prior to the date listed, and end at sundown of the date in question unless otherwise noted.)
The last two to three weeks in October (and, occasionally, the first week of November) are normally the only time of the year during which all of the "Big Four" major professional sports leagues in the U.S. and Canada schedule games; the National Basketball Association begins its preseason and about two weeks later starts the regular season, the National Hockey League is in the first month of its regular season, the National Football League is about halfway through its regular season, and Major League Baseball is in its postseason with the League Championship Series and World Series. Days on which all four leagues play are colloquially known as a sports equinox. [18]
April is the fourth month of the year in the Gregorian and Julian calendars. Its length is 30 days.
August is the eighth month of the year in the Julian and Gregorian calendars. Its length is 31 days.
Arbor Day is a secular day of observance in which individuals and groups are encouraged to plant trees. Today, many countries observe such a holiday. Though usually observed in the spring, the date varies, depending on climate and suitable planting season.
December is the twelfth and final month of the year in the Julian and Gregorian calendars. Its length is 31 days.
February is the second month of the year in the Julian and Gregorian calendars. The month has 28 days in common years and 29 in leap years, with the 29th day being called the leap day. February is the third and last month of meteorological winter in the Northern Hemisphere. In the Southern Hemisphere, February is the third and last month of meteorological summer.
January is the first month of the year in the Julian and Gregorian calendars. Its length is 31 days. The first day of the month is known as New Year's Day. It is, on average, the coldest month of the year within most of the Northern Hemisphere and the warmest month of the year within most of the Southern Hemisphere. In the Southern hemisphere, January is the seasonal equivalent of July in the Northern hemisphere and vice versa.
June—abbreviated Jun—is the sixth month of the year in the Julian and Gregorian calendars—the latter the most widely used calendar in the world. Its length is 30 days. June succeeds May and precedes July. This month marks the start of summer in the Northern Hemisphere and contains the summer solstice, which is the day with the most daylight hours. In the Southern Hemisphere, June is the start of winter and contains the winter solstice, the day with the fewest hours of daylight out of the year.
July is the seventh month of the year in the Julian and Gregorian calendars. Its length is 31 days. It was named by the Roman Senate in honour of Roman general Julius Caesar in 44 B.C., being the month of his birth. Before then it was called Quintilis, being the fifth month of the calendar that started with March.
March is the third month of the year in both the Julian and Gregorian calendars. Its length is 31 days. In the Northern Hemisphere, the meteorological beginning of spring occurs on the first day of March. The March equinox on the 20 or 21 marks the astronomical beginning of spring in the Northern Hemisphere and the beginning of autumn in the Southern Hemisphere, where September is the seasonal equivalent of the Northern Hemisphere's March.
May is the fifth month of the year in the Julian and Gregorian calendars. Its length is 31 days.
November is the eleventh and penultimate month of the year in the Julian and Gregorian calendars. Its length is 30 days. November was the ninth month of the calendar of Romulus c. 750 BC. November retained its name when January and February were added to the Roman calendar. November is a month of late spring in the Southern Hemisphere and late autumn in the Northern Hemisphere. Therefore, November in the Southern Hemisphere is the seasonal equivalent of May in the Northern Hemisphere and vice versa. In Ancient Rome, Ludi Plebeii was held from November 4–17, Epulum Jovis was held on November 13 and Brumalia celebrations began on November 24. These dates do not correspond to the modern Gregorian calendar.
September is the ninth month of the year in the Julian and Gregorian calendars. Its length is 30 days.
Summer or summertime is the hottest and brightest of the four temperate seasons, occurring after spring and before autumn. At or centred on the summer solstice, daylight hours are the longest and darkness hours are the shortest, with day length decreasing as the season progresses after the solstice. The earliest sunrises and latest sunsets also occur near the date of the solstice. The date of the beginning of summer varies according to climate, tradition, and culture. When it is summer in the Northern Hemisphere, it is winter in the Southern Hemisphere, and vice versa.
Father's Day is a holiday honoring one's father, as well as fatherhood, paternal bonds, and the influence of fathers in society. The holiday complements similar celebrations honoring family members, such as Mother's Day and, in some countries, Siblings Day, and Grandparents' Day. The day is held on various dates across the world, and different regions maintain their own traditions of honoring fatherhood.
In the United States, public holidays are set by federal, state, and local governments and are often observed by closing government offices or giving government employees paid time off. The federal government does not require private businesses to close or offer paid time off, as is the case for most state and local governments, so employers determine which holidays to observe.
Children's Day is a commemorative date celebrated annually in honour of children, whose date of observance varies by country. In 1925, International Children's Day was first proclaimed in Geneva during the World Conference on Child Welfare. Since 1950, it is celebrated on 1 June in many countries, which follow the suggestion from Women's International Democratic Federation. World Children's Day is celebrated on 20 November to commemorate the issuance of the Declaration of the Rights of the Child by the UN General Assembly on 20 November 1959, along with the adoption of the Convention on the Rights of the Child on that date in 1989. In some countries, it is Children's Week and not Children's Day.
An Armed Forces Day, alongside its branch-specific variants often referred to as Army or Soldier's Day, Navy or Sailor's Day, and Air Force or Aviator's Day, is a holiday dedicated to honoring the armed forces, or one of their branches, of a sovereign state, including their personnel, history, achievements, and perceived sacrifices. It's often patriotic or nationalistic in nature, carrying propaganda value outside of the conventional boundaries of a military's subculture and into the wider civilian society. Many nations around the world observe this day. It is usually distinct from a Veterans or Memorial Day, as the former is dedicated to those who previously served and the latter is dedicated to those who perished in the fulfillment of their duties.
World Vegetarian Day is observed annually around the planet on October 1. It is a day of celebration established by the North American Vegetarian Society in 1977 and endorsed by the International Vegetarian Union in 1978, "To promote the joy, compassion and life-enhancing possibilities of vegetarianism." It brings awareness to the ethical, environmental, health, and humanitarian benefits of a vegetarian lifestyle. World Vegetarian Day initiates the month of October as Vegetarian Awareness Month, which ends with November 1, World Vegan Day, as the end of that month of celebration. Vegetarian Awareness Month has been known variously as "Reverence for Life" month, "Month of Vegetarian Food", and more.
