It’s the second Monday in October and therefore Columbus Day in the USA. Columbus ‘discovered’ the Americas around this time in 1492 (the indigenous people had been here LONG before that, of course). And he didn’t really discover what is today the USA. Wikipedia put it like this : Christopher Columbus (c. 31 October 1451 – 20 May 1506) was a navigator, colonizer, and explorer from the Republic of Genoa, in northwestern Italy, whose voyages across the Atlantic Ocean led to general European awareness of the American continents in the Western Hemisphere. Spain and the other Americas celebrate Columbus Day as well – but not Canada.
