November

November closes the year's third quarter with Children's Day, National Integration themes, and a run of scientific and legal observances.

• 7 November — National Cancer Awareness Day, marking the birth anniversary of Marie Curie (born 7 November 1867), the physicist and chemist whose pioneering research on radioactivity laid the foundation for later cancer-treatment technologies.
• 9 November — Legal Services Day, marking the date in 1995 that the Legal Services Authorities Act, 1987 came into force, establishing a nationwide network for providing free and competent legal services to weaker sections of society.
• 12 November — National Bird Day (also observed in some Indian sources as National Public Health Day tied to other dates — treat this loosely, as regional variation exists).
• 14 November — Children's Day (Bal Diwas), marking the birth anniversary of Jawaharlal Nehru, India's first Prime Minister, who was widely known for his deep fondness for children (affectionately called "Chacha Nehru") — observed since shortly after his death in 1964, distinct from Universal Children's Day (20 November), established by the UN in 1954 and later fixed to that date in 1959 to mark the adoption of the Declaration of the Rights of the Child (see Commonly Confused Days).
• 14 November — World Diabetes Day, also observed on the same date, marking the birth anniversary of Sir Frederick Banting, co-discoverer of insulin in 1921 — another example of one calendar date carrying two entirely unrelated observances.
• 17 November — National Epilepsy Day, an Indian observance raising awareness of epilepsy, its treatment, and the social stigma surrounding it.
• 19 November — International Men's Day, observed in many countries (though not a formal UN day) to focus attention on men's and boys' health, gender relations, and positive role models.
• 20 November — Africa Industrialisation Day, designated by the UN General Assembly in 1989, promoting awareness of the challenges and opportunities facing Africa's industrial development.
• 20 November — Universal Children's Day, established by the UN, marking the anniversary of both the 1959 Declaration of the Rights of the Child and the 1989 UN Convention on the Rights of the Child, both adopted on this same date thirty years apart — a deliberate double-anniversary choice, distinct from India's own 14 November Children's Day.
• 21 November — World Television Day, marking the date in 1996 that the first World Television Forum was held at the United Nations.
• 26 November — Constitution Day (Samvidhan Diwas), marking the date in 1949 that the Constituent Assembly of India adopted the Constitution of India — it came into force two months later, on 26 January 1950 — observed as Constitution Day since 2015, on the occasion of the 125th birth anniversary of Dr B.R. Ambedkar, chairman of the Constitution's Drafting Committee. The same date, 26 November, is also observed internationally as a memorial for the 26/11 Mumbai terror attacks (2008).
• 29 November — International Day of Solidarity with the Palestinian People, established by the UN General Assembly in 1977.

Memory hook — "Two months, one Constitution": the Constitution was adopted on 26 November 1949 (Constitution Day) and came into force on 26 January 1950 (Republic Day) — a two-month gap that is one of the single most frequently tested date-pairs in the entire Indian polity-and-observances syllabus.

Practice Recall: Without checking, state the precise difference between Children's Day (India) and Universal Children's Day (UN) — the date, the person or document behind each, and the year each was first observed.
