Overview

August 10 is the 222nd day of the year in the Gregorian calendar and the 223rd in leap years. In a common year there are 143 days remaining until December 31. The date typically falls under the astrological sign of Leo and lies in late northern-hemisphere summer and southern-hemisphere winter.

Calendar position

The day’s placement in the annual cycle means seasonal activities in the Northern Hemisphere often relate to harvest preparation, vacations and late-summer festivals. Its numeric position changes in leap years; for more about leap-year adjustments see leap years and for the system that defines the date see the Gregorian calendar.

History and observances

Several historical and cultural observances fall on August 10. Notable examples include the Feast of Saint Lawrence, a long-established Christian commemoration of the 3rd-century martyr, and civic commemorations such as Ecuador’s First Cry of Independence (the start of its independence movement in 1809). Modern awareness days observed on this date include World Lion Day, focused on conservation and education.

Notable people and commemorations

The date is used to mark births and deaths of public figures, and national or local anniversaries. For example, Herbert Hoover, the 31st president of the United States, was born on August 10. Religious and civic calendars commonly list additional local saints’ days, municipal holidays and remembrance events on this date.

Astronomical and cultural context

Mid-August is often associated with meteor activity near the Perseid peak (which typically occurs a few days later), warm-weather traditions in many regions, and various cultural festivals. Because the calendar date is fixed, its literal seasonal meaning depends on hemisphere and latitude; communities adapt observances accordingly.

Common uses and distinctions

  • Religious observance: Feast days and liturgical commemorations.
  • National anniversaries: Independence or founding events in some countries.
  • Awareness days: International and conservation-focused observances like World Lion Day.

Across cultures the date serves as a convenient marker for anniversaries, public holidays and seasonal activities, its significance varying by local history and tradition.
