How we source these
Public holidays are taken from official government sources for each country and cover national holidays only. The United States, Canada and Australia all have significant state and provincial holidays that are not shown, and India’s system of state, optional and restricted holidays means only three days are observed nationwide. Where a government has not yet published a year, we say so rather than guess. Always check the official source for the country concerned rather than relying on this alone.
September 13th through history
Wolfe at Quebec, and a boy born in Llandaff
On September 13th 1759 a British force under James Wolfe climbed a goat path up the cliffs above Quebec in darkness and formed line on the Plains of Abraham. The fighting that followed lasted a matter of minutes; Wolfe was killed on the field and his opponent Montcalm died the next morning, and French rule in Canada effectively ended with them. Wolfe is said to have recited Gray’s Elegy in the boats the night before, remarking that he would rather have written it than take Quebec.
Roald Dahl, the author who gave the world’s children Charlie and the Chocolate Factory and Matilda, was born in Llandaff, Cardiff, on September 13th 1916, to Norwegian parents. He flew fighters in the war, then wrote in a brick hut at the bottom of his garden in Buckinghamshire, in an old armchair with a sleeping bag over his legs. His birthday is now kept as Roald Dahl Day.
Super Mario Bros. was released in Japan on September 13th 1985. Eight years later, Yitzhak Rabin and Yasser Arafat shook hands on the White House lawn.
Also born on September 13th were Jacqueline Bisset, the English actress who found stardom in Hollywood films, in 1944, and Claudette Colbert, the Oscar-winning star of Hollywood’s golden age, in 1903.
Born on September 13th: star sign, birthstone and birth flower
Roald Dahl and Jacqueline Bisset — both named above — share this star sign with everyone else born in the same window.
Star sign
Virgo — an Earth sign ruled by Mercury, symbolised by the Maiden.
Birthstone
Sapphire for September.
Birth flower
Aster (primary), also Morning Glory — most commonly cited sources agree on aster as the main September flower.
None of this is settled fact in the way the history above is — zodiac dates, birthstones and birth flowers are conventions rather than laws, and different sources hedge them slightly differently. The birthstone is the most standardised of the three (set by the trade in 1912 and revised since); the birth flower is the least, resting on Victorian tradition rather than any governing body.
