The source[1] dates it firmly — the earthquake "hit the Iberian Peninsula and Northwest Africa on the morning of Saturday, 1 November, Feast of All Saints, at around 09:40 local time". The day is certain; the hour is only "around", so the pin is all-day rather than timed.
A magnitude 7.7-or-greater earthquake struck off Cape St. Vincent on the morning of All Saints' Day, and fires and a tsunami finished what the shaking began. Between 30,000 and 40,000 died in Lisbon alone.

Wikipedia[1] says it "opened in 1760 on Via Condotti" and names no month or day, so the pin takes that year's last day.
Antico Caffè Greco opened in 1760 a few steps from the Spanish Steps and became the room where the Grand Tour sat down - Keats, Byron, Goethe, Stendhal and Casanova among the names attached to it. It is the oldest cafe in Rome, but it lost a long court fight with its landlord over the rent: after the Court of Cassation upheld the lease termination, police sealed the premises it had occupied for more than two and a half centuries on 8 October 2025.

Demel was established in 1786 a few steps from the Hofburg and became confectioner to the imperial court, a title it still puts on its boxes. Its window on the Kohlmarkt and its Anna Torte made it one of the fixtures by which Vienna measures its café culture, and it sits at the centre of a long argument with Hotel Sacher over who may call a cake a Sachertorte.

Wikipedia's[3] Salamanca (locomotive) article and the Real Yorkshire Blog[2] both date the locomotive's first public run to 24 June 1812.
At the Round Foundry in Holbeck, Leeds, engineering firm Fenton, Murray and Wood built the Salamanca, the world's first commercially successful steam locomotive, which first ran publicly on 24 June 1812. Designed by Matthew Murray for John Blenkinsop's rack-and-pinion Middleton Railway, it hauled coal using a toothed rail system.

The source[1] fixes the climax to the day: "the Mount Tambora eruption reached a violent climax on 10 April 1815", with smaller phreatic activity continuing for months afterwards.
The most powerful volcanic eruption in recorded history threw 37-45 cubic kilometres of rock into the atmosphere from Sumbawa. Its veil of ash cooled the planet enough to give 1816 the name the Year Without a Summer.
