Wikipedia's October 25 page is a secondary source, so treat the list below as a starting point and follow the links for fuller accounts.
1971: the China seat at the United Nations
On this date the General Assembly adopted Resolution 2758 by 76 votes to 35, with 17 abstentions. It recognised representatives of the People's Republic of China as the only legitimate representatives of China at the UN. Our full guide is UN Resolution 2758 explained.
1415: Agincourt
Wikipedia records that Henry V's lightly armoured English infantry and archers defeated the heavily armoured French cavalry at Agincourt. The page does not give casualty figures in the excerpt we checked, so we give none.

Festivals and Observances on or Around October 25, 2026
Sharad Purnima
HinduTone, using Hyderabad timings, gives Sunday, October 25 for Sharad Purnima. The Purnima tithi begins at about 11:55 AM that day and runs until about 9:41 AM on October 26, with moonrise at 5:07 PM. DekhoPanchang also lists Sunday, October 25, and says the date follows the midnight (Nishita) rule. Bengal observes Kojagari Lakshmi Puja and Odisha observes Kumar Purnima on the same night. Read our Sharad Purnima 2026 guide for the tithi logic and customs.
Not every calendar agrees. One site we checked gave Monday, October 26 and another, set to Houston time, gave a different evening. Local sunrise, moonrise and the tithi window all shift by city, so check a panchang for your own location.
Valmiki Jayanti
HinduTone lists Maharishi Valmiki Jayanti on Monday, October 26, the day after Sharad Purnima. We did not open an official calendar for it, so confirm the date locally.
The end of the festival run
Dussehra falls on October 20 in most calendars, and Diwali follows in November. See our Dussehra guide and Diwali 2026 calendar for the sequence.
Relevant Current Affairs
Clocks go back in Europe
Universal Time Date reports that the UK moves from British Summer Time back to Greenwich Mean Time on Sunday, October 25, at 01:00 UTC, so clocks go from 2:00 AM to 1:00 AM. Central European clocks go from 3:00 AM to 2:00 AM at the same instant. The United States changes a week later, on November 1. India does not observe daylight saving time, so the gap between Indian and UK time becomes 5 hours 30 minutes from October 25.
International meetings
We did not open an official calendar confirming a summit or ministerial meeting on October 25 itself, so we name no meeting, participants or outcomes.
Upcoming Sporting Events
Formula 1: United States Grand Prix
The official F1 page lists the race at the Circuit of the Americas in Austin on Sunday, October 25, 56 laps or two hours, whichever comes first. The grand prix runs 15:00 to 17:00 local time (UTC-5 on the page), and this is not a sprint weekend. Subject to the page's note that times may change, that is about 1:30 AM IST on Monday, October 26 for the 3 PM local start, a conversion we calculated ourselves, so confirm it with your broadcaster.
Crash.net reported after the Singapore round that Andrea Kimi Antonelli led the drivers' standings on 340 points, ahead of George Russell on 238 and Lewis Hamilton on 229, and that he could clinch the title as soon as Austin. That is a possibility, not a result. Qualifying is on Saturday, October 24.
India women v Zimbabwe women, second ODI
The ICC lists the second ODI in Vadodara on Sunday, October 25. We could not confirm start times. Our series guide has the schedule and squads.
