August 11

Characteristics

The date usually falls under the astrological sign of Leo (approximately July 23–August 22). Around this time the Perseid meteor shower, one of the most active annual showers, often reaches peak activity, making August evenings popular for stargazing. In many regions August 11 is a warm midsummer day, associated with agricultural cycles, vacations and outdoor festivals in temperate climates.

Historical and civic observances

Several countries and territories mark national events on August 11. A notable example is the Independence Day of Chad, observed annually on this date. Governments, military organizations and cultural groups sometimes schedule ceremonies or commemorations on fixed calendar dates such as August 11 to mark historical milestones.
