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.
August 21st through history
The Mona Lisa walks out of the Louvre
On August 21st 1911 Vincenzo Peruggia, a Louvre handyman who had helped fit the museum’s glass cases, let himself in early on a Monday morning, lifted the Mona Lisa off four pegs and walked out with it wrapped in his workman’s smock. The gap on the wall was not noticed for more than a day. Crowds then came to look at the empty space, in greater numbers than had ever come to look at the painting. It was recovered in Florence two years later.
Princess Margaret, younger sister of Queen Elizabeth II, was born on August 21st 1930 at Glamis Castle in Angus, the first member of the royal family to be born in Scotland since Charles I in 1600. Her birth was registered locally, and the entry sits in the Angus register between two Glamis families of no particular distinction.
A vast cloud of carbon dioxide was released from Lake Nyos in Cameroon on August 21st 1986 and flowed down the surrounding valleys, killing 1,746 people. Engineers have since installed pipes to vent the gas from the lake bed in a controlled way.
Kenny Rogers, the country singer known for The Gambler, was born on August 21st 1938, Kim Cattrall, the actress known for Sex and the City, in Liverpool in 1956, and Usain Bolt, the sprinter regarded as the fastest man ever timed, in 1986.
Born on August 21st: star sign, birthstone and birth flower
Princess Margaret and Usain Bolt — both named above — share this star sign with everyone else born in the same window.
Star sign
Leo — a Fire sign ruled by the Sun, symbolised by the Lion.
Birthstone
traditionally Sardonyx, or Peridot or Spinel in the modern list for August.
Birth flower
Gladiolus (primary), also Poppy — most commonly cited sources agree on gladiolus as the main August 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.
Gift ideas for a August 21st birthday
A small, themed starting point rather than a shopping list — sardonyx for the stone, Leo for the sign, and the sky itself on the day.
