November marks a diverse array of cultural, historical, and awareness observances across the United States and worldwide.

National American Indian Heritage Month, originally established as American Indian Week in 1976 through legislation authored by Jerry C. Elliott-High Eagle (Osage/Cherokee), became a monthlong tribute in 1990. It aims to provide Native American communities a platform to share their traditions, culture, and beliefs.

The month also features National Novel Writing Month, widely known as NaNoWriMo, a challenge encouraging participants to draft 50,000 words of original fiction. Although the official forums supporting the event closed in early 2025, participants continue to engage independently. Several novels originating from this challenge have achieved commercial success, including bestsellers and inspiring film adaptations.

Movember, originating in Australia, encourages men to grow mustaches throughout November to raise awareness of men's health issues, including testicular and prostate cancers as well as mental health challenges.

On November 1 and 2, Día de los Muertos (Day of the Dead) is observed primarily in Mexico and among Mexican communities globally. The holiday honors deceased loved ones, with customs such as decorating home altars with marigolds, sugar skulls, and favorite foods. The origins are debated, potentially reflecting a blend of Indigenous, pre-Hispanic traditions and Christian observances. The holiday is recognized by UNESCO as an intangible cultural heritage of Mexico.

Federal and many state and local elections will be held on November 3, consistent with established U.S. practice of voting on the Tuesday following the first Monday in November during even-numbered years. The timing historically reflected agricultural schedules and voters’ travel conditions. States vary in their provisions for early voting, vote-by-mail, and time off to vote.

Diwali, the Hindu festival of lights, begins on November 6 and lasts several days. Celebrated by Hindus, Jains, and Sikhs with regional variations, it symbolizes the triumph of light and knowledge over darkness and ignorance. Traditions include lighting lamps, creating rangoli designs, and sharing food and sweets.

The Bahá’í Faith marks the Twin Holy Birthdays on November 10 and 11, celebrating the births of its central figures, the Báb and Bahá’u’lláh. Observances include prayer, reflection, and service.

Veterans Day on November 11 honors those who have served in the military, originally commemorated as Armistice Day on the end of World War I. Activities typically include parades and a moment of silence at 2:11 p.m. Eastern time.

World Diabetes Day on November 14, led by the International Diabetes Federation, coincides with the birthday of insulin co-discoverer Frederick Banting. The 2026-2027 theme emphasizes early detection and intervention to reduce risks related to diabetes.

America Recycles Day, observed on November 15 and managed by Keep America Beautiful, promotes recycling and environmental stewardship.

Also on November 15, World Prematurity Day raises awareness about premature birth, a leading cause of infant mortality worldwide.

November 19 observes World Toilet Day, highlighting global sanitation challenges. Approximately 3.4 billion people lack access to safely managed sanitation, a key target in the United Nations’ Sustainable Development Goals.

International Men’s Day, also November 19, focuses on positive male role models, men’s health, gender relations, and equality, addressing social challenges affecting men.

November 20 is recognized as Children’s Day, commemorating the adoption of the U.N.’s Declaration of the Rights of the Child in 1959 and the Convention on the Rights of the Child in 1989, although the U.S. has not ratified the latter. The day also marks the Transgender Day of Remembrance, which honors those killed due to anti-transgender violence, often through vigils and public readings.

National Adoption Day on November 21 promotes finalizing adoptions, with efforts leading to permanent homes for over 95,000 children since 1999.

The Sikh festival Guru Nanak Gurpurab, celebrated on November 24, honors the birth of the religion’s founder. The day includes processions, hymns, and community meals called Langar.

Thanksgiving in the United States, observed on the fourth Thursday of November (November 26 in 2026), is a longstanding harvest celebration featuring family gatherings, feasting, parades, and football games. The holiday’s federal status was established by Congress in 1941.

Finally, November 27 features two contrasting observances: Black Friday, the traditional start of the Christmas shopping season marked by sales and crowds, and Buy Nothing Day, a protest against consumerism during the holiday season, sometimes involving acts of civil disruption.

These observances collectively reflect a wide spectrum of cultural heritage, public health awareness, social justice, and community engagement throughout the month.
