2nd decan of Leo: Jupiter
Each sign is divided into three decans, 10° slices that the Sun crosses in about ten days each. August 10 falls in the second decan of Leo (about August 2–11), which the traditional Chaldean system assigns to Jupiter. Astrologers say that adds optimism, generosity and big-picture thinking.
Jupiter widens the sign's horizons, adding faith in the future, a generous streak and an appetite for growth, travel and learning.
The number 10 in numerology
The 10 combines the 1's initiative with a full cycle's experience. A birthday on the 10th is read as self-reliant, ambitious and quietly resilient.

What zodiac sign is August 10?
August 10 falls in Leo, which runs from July 23 to August 22 in the tropical zodiac. The Sun changes sign at a slightly different moment each year, so the boundary can fall a day or so either side of these dates. If you were born close to the edge, your birth year, time and place decide it.
Is August 10 a cusp birthday?
Not by the usual definition, which counts the first and last couple of days of a sign. August 10 is day 19 of Leo season, so it is normally read as a clear Leo birthday.
Which decan is August 10?
August 10 is in the second decan of Leo (August 2–11). In the traditional Chaldean system this decan is ruled by Jupiter, which astrologers say adds its own flavour to Leo. Some modern astrologers assign decan rulers by element instead, which gives different planets, and decans are strictly 10° slices of the zodiac, so the date range is approximate.
What are the birthstone and flower for August?
The modern birthstone for August is Peridot and the birth flower is the gladiolus. These come from calendar tradition rather than astrology, and the lists vary by country and source.
