August 23 is the 235th day of the year in the Gregorian calendar and the 236th in leap years. There are 130 days remaining until the end of the year. In calendar references it is often noted for its place near the transition from Leo to Virgo in modern astrology and for seasonal markers in both hemispheres: late summer in the Northern Hemisphere and late winter in the Southern Hemisphere. The date’s numbering and movement from year to year reflect leap-year adjustments in the Gregorian calendar system.

Calendar context and astronomy

Because of leap years the ordinal number of August 23 is sometimes given with a parenthetical note; it follows August 22 and precedes August 24 consistently, but weekday alignment shifts annually. Astronomically it lies well past the midsummer solstice and before the autumnal equinox in the Northern Hemisphere, so daylight hours are steadily shortening there and lengthening in the Southern Hemisphere.

History and observances

  • 1939 — The Molotov–Ribbentrop Pact between Nazi Germany and the Soviet Union was signed on August 23, a fact that later led many countries to mark the date for remembrance and debate.
  • 1944 — On August 23 Romania carried out a coup (King Michael’s Coup) that had major effects on World War II alignments in Eastern Europe.
  • Commemoration — In parts of Europe and elsewhere the date is observed as a day to remember victims of totalitarian regimes; it is sometimes called Black Ribbon Day or a day of remembrance for those affected by Stalinist and Nazi crimes.

Over time the date has become a focal point for anniversary pieces and cultural remembrances.
