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 17th through history
A bridge too far at Arnhem
Operation Market Garden began on September 17th 1944, the largest airborne operation attempted to that point, intended to seize a corridor of Dutch bridges and finish the war by Christmas. The British 1st Airborne Division was dropped some eight miles from its objective at Arnhem. A single battalion under John Frost reached the northern end of the bridge and held it for four days against armour it had been assured was not there. Of roughly ten thousand men who landed at Arnhem, fewer than 2,500 came back across the Rhine.
The Space Shuttle Enterprise was rolled out at Palmdale in California on September 17th 1976. She had been due to be called Constitution until a write-in campaign by Star Trek viewers changed the name; most of the programme’s cast attended, and the orbiter never flew in space.
On September 17th 1939 Soviet forces invaded Poland from the east, sixteen days after the Germans crossed from the west. The Camp David accords were signed in Washington on the evening of September 17th 1978, American time, after thirteen days of negotiation.
Two of Britain’s best-known racing drivers were born on this date: Stirling Moss, long regarded as the finest driver never to win the world championship, in 1929, and Damon Hill, who went on to win it, in 1960. Anne Bancroft, the Oscar-winning actress remembered for The Graduate, was born in 1931, and Baz Luhrmann, the director known for his flamboyant visual style, in 1962.
Born on September 17th: star sign, birthstone and birth flower
Stirling Moss and Damon Hill — 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.

A small, themed starting point rather than a shopping list — sapphire for the stone, Virgo for the sign, and the sky itself on the day.
