First week: 1 to 7 October

1 October: International Day of Older Persons, International Coffee Day, World Vegetarian Day
2 October: Gandhi Jayanti, International Day of Non-Violence
4 October: World Animal Day
5 October: World Teachers' Day, World Habitat Day
6 October: World Cerebral Palsy Day
7 October: World Cotton Day

Gandhi Jayanti, marking the birth anniversary of Mahatma Gandhi on 2 October 1869, is also observed worldwide as the International Day of Non-Violence, one of the few Indian national holidays with a matching UN-designated day attached to it. The week otherwise leans quiet, built around teachers, animals and cotton rather than any single headline event.

Second week: 8 to 14 October

8 October: Indian Air Force Day, World Sight Day

11 October: International Day of the Girl Child, National Coming Out Day
12 October: World Arthritis Day
13 October: International Day for Disaster Risk Reduction, World Thrombosis Day, Ada Lovelace Day
14 October: World Standards Day

Indian Air Force Day, on 8 October, marks the establishment of the IAF in 1932 and is usually marked with parades and air shows at Chandigarh or Hindon. The rest of the week is dense with health-linked observances, from mental health on the 10th to arthritis on the 12th, making this stretch a favourite for GK questions on medical awareness days.

Third week: 15 to 21 October

15 October: World Students' Day, International Day of Rural Women, Global Handwashing Day, White Cane Safety Day
16 October: World Food Day, World Spine Day, National Mammography Day, Boss's Day
17 October: International Day for the Eradication of Poverty, International Archaeology Day
20 October: Dussehra (Vijayadashami), World Osteoporosis Day, International Chefs Day
21 October: Police Commemoration Day (India)

World Students' Day, on 15 October, marks the birth anniversary of Dr APJ Abdul Kalam, while World Food Day the next day is organised by the Food and Agriculture Organization and has run since 1945. Dussehra on the 20th brings the week to its loudest point, with Ravan Dahan events drawing large crowds in cities across North India.

Fourth week: 22 to 28 October

24 October: United Nations Day, World Polio Day, World Development Information Day
25 October: Sharad Purnima
27 October: World Day for Audiovisual Heritage

United Nations Day, on 24 October, marks the anniversary of the UN Charter coming into force in 1945, and is often bundled with World Polio Day the same date, a coincidence that trips up quiz-takers most years. Sharad Purnima on the 25th is the only major festival in an otherwise UN-heavy week.

Final days: 29 to 31 October

29 October: Karva Chauth, World Stroke Day, World Psoriasis Day
31 October: National Unity Day (Rashtriya Ekta Diwas), World Savings Day, World Cities Day, Halloween

Karva Chauth on the 29th and National Unity Day on the 31st bookend a short final stretch that also carries three separate UN or civic observances on the same last day of the month. It is a reminder of how crowded 31 October gets, between Halloween, World Cities Day and World Savings Day all landing together.
