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.
December 21st through history
The night Pan Am 103 came down
On the evening of December 21st 1988 Pan Am Flight 103 was destroyed by a bomb in the hold above the Scottish border town of Lockerbie, thirty-eight minutes after leaving Heathrow for New York. All 259 people on board were killed, together with eleven residents of the town: 270 in all. It was four days before Christmas and many of the passengers were students flying home for the holidays. It remains the worst terrorist attack ever carried out in Britain.
The search covered 845 square miles of the Borders, the largest area ever examined in a British criminal investigation. Townspeople washed, pressed and returned the belongings of the dead to their families. In 2001 a Libyan intelligence officer was convicted of the bombing by a Scottish court convened, uniquely, on neutral ground in the Netherlands.
Apollo 8 launched from Florida on December 21st 1968, the first crewed spacecraft to leave Earth orbit, carrying Borman, Lovell and Anders on a three-day crossing to the Moon. Thirty-one years earlier, Snow White and the Seven Dwarfs had opened in Los Angeles, the first full-length cel-animated feature and the making of the Disney studio.
The winter solstice falls on 21 or December 22nd. In London the sun rises around eight and is gone before four; at Stonehenge the great trilithon frames the midwinter sunset, which is what the builders appear to have cared about most.
Born on December 21st: star sign, birthstone and birth flower
Jane Fonda and Samuel L. Jackson — both named above — share this star sign with everyone else born in the same window.
Star sign
Sagittarius — a Fire sign ruled by Jupiter, symbolised by the Archer. If you were born right on the cusp, sources vary by a day either way on exactly where one sign ends and the next begins.
Birthstone
traditionally Turquoise or Lapis Lazuli, or Turquoise, Tanzanite or Zircon in the modern list for December.
Birth flower
Narcissus or Holly (primary), also Poinsettia — most commonly cited sources agree on narcissus or holly as the main December 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 — turquoise or lapis lazuli for the stone, Sagittarius for the sign, and the sky itself on the day.
