On This Day in History: October 31
Wikipedia's October 31 page is a secondary source, so treat the entries below as a starting point and follow the links for fuller explainers.
1875: Vallabhbhai Patel is born
Patel, born in Nadiad in present-day Gujarat, became India's first Deputy Prime Minister and Home Minister. Our Sardar Patel anniversary guide covers his life and the 2026 programme.
1984: Indira Gandhi is assassinated
Prime Minister Indira Gandhi was shot at her New Delhi residence by two of her security guards and died the same day. Anti-Sikh violence followed in the days after. Read the explainer on the assassination for the context.
1517: Martin Luther and the 95 Theses
Tradition holds that Martin Luther posted his 95 Theses in Wittenberg on this date, an event associated with the start of the Protestant Reformation. Some historians debate how the theses were first circulated, so treat the "posting" detail as traditional rather than certain. Reformation Day is observed in parts of Germany, Slovenia and Chile, and by many Lutheran and Reformed churches.
Other entries
Wikipedia also lists Nevada's admission as the 36th US state (1864), the completion of Mount Rushmore (1941), the first resident crew arriving at the International Space Station (2000) and the world population reaching seven billion (2011, a symbolic milestone based on estimates). The same date saw the deaths of the magician Harry Houdini (1926) and the Indian composer Sachin Dev Burman (1975), and the Hindi-Punjabi poet Amrita Pritam in 2005. We have not independently researched these entries.
Festivals and Observances on October 31, 2026
Rashtriya Ekta Diwas
India observes National Unity Day on Patel's birthday. The official Incredible India listing places the main 2026 event at the Statue of Unity complex in Ekta Nagar, Gujarat, with a Unity Parade by central and state police forces, a Prime Minister's address, cultural performances by over 900 artists, a tableau parade and an evening light-and-sound show. It also mentions a "Run for Unity" and pledge ceremonies across the country. It is an observance, not a listed national holiday; school and office timings depend on local rules.
World Cities Day
The United Nations observes World Cities Day on October 31. UN-Habitat lists the 2026 global observance in Fuzhou, China, under the theme "Regenerating the City: Adequate Housing for All". Our World Cities Day guide has the details.
Halloween, Samhain and Reformation Day
Halloween is celebrated on October 31 in the United States, Canada, Ireland, the United Kingdom and elsewhere, and its roots are linked to the Gaelic festival of Samhain. It is a cultural celebration rather than a public holiday, and it has no official status in India. Reformation Day, mentioned above, is a church observance.
What the panchang says
Shubh Panchang lists Krishna Shashthi until 4:57 PM on October 31, followed by Saptami, and names Sardar Patel Jayanti as the day's observance with no vrat. The page does not name a city for its timings, so confirm times for your own location. Our Diwali 2026 calendar shows how the festival season continues.
Relevant Current Affairs
We did not find an official source confirming a summit or ministerial meeting on October 31 itself, so we name no meeting, participants or outcomes. Vigilance Awareness Week, which our coverage of the 2026 theme lists as running from October 26 to November 1, includes the date, since it is timed around Patel's birth anniversary.
Clock changes also affect time conversions. Europe and the United Kingdom moved their clocks back on October 25, while the United States changes on November 1, so time gaps with India vary for a few days. Our guide to the Europe clock change explains the arithmetic.
