2nd decan of Leo: Jupiter
Each sign is divided into three decans, 10° slices that the Sun crosses in about ten days each. August 5 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.

What zodiac sign is August 5?
August 5 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 5 a cusp birthday?
Not by the usual definition, which counts the first and last couple of days of a sign. August 5 is day 14 of Leo season, so it is normally read as a clear Leo birthday.
Which decan is August 5?
August 5 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.
