In Western astrology, an August 4 birthday falls in Leo, in the second decan, with Sun as the sign's ruler and Jupiter as the decan's. In numerology the day gives birthday number 4. The Life Path also uses the birth year. Leo is fixed and fire.

August 4 zodiac sign and personality
Jupiter expands, 4 consolidates: the 4th of August holds both instincts. Eleven degrees into Leo, in the Jupiter decan, big ambitions meet practical method. Interpretive astrology describes a confident planner who dreams at scale and then draws up the schedule. When the two impulses cooperate, this birthday tends to build things that are both generous and durable.
On August 4 the Sun usually sits at about 11° Leo, in the second decan, where Jupiter is the sub-ruler alongside Sun. Jupiter, the planet of Sagittarius, acts as sub-ruler for Leo from 10 to 19 degrees, which covers roughly the first ten days of August. This decan tends to add breadth and humour to the Lion's confidence. Natives are commonly pictured as big-hearted teachers, hosts and storytellers who like to share what they know and enjoy. A love of travel, ideas and grand plans often shows early. Jupiter magnifies, so the generosity can become overpromising and the confidence a little too sure of itself. When grounded, this decan tends to inspire others to think larger about their own lives.
August 4 in numerology
A 4th-of-the-month birthday gives a birthday number of 4, with no further reduction needed. In numerology the birth day acts as a supplementary number, describing practical talents that sit beside the Life Path. The 4 stands for the square: four walls, four seasons, a stable base. Anyone born on the 4th is often pictured as organised, trustworthy and good at turning plans into schedules. They tend to prefer a method that has been tested to one that merely sounds exciting. The growing edge for 4s is usually flexibility, letting the structure bend when circumstances genuinely change.
The Life Path, the main number in a numerology chart, also uses the birth year, so it changes from one August 4 birthday to the next: it is 1 for 1960, 2 for 1970, 3 for 1980 and 4 for 1990, for example.
Born on August 4: season, famous birthdays and Chinese zodiac
An August birthday falls in late northern summer, a season of early harvests and holidays, and in late winter for the southern hemisphere, when the first blossom starts to appear. Leo holds most of the month, with Virgo arriving around August 22 or 23. August is month 8 in numerology, associated with ambition, authority and material skill, a fitting partner for Leo's confidence. August 4 is the 216th day of the year (217th in a leap year). By August 23, 19 days later, the Sun has usually moved on into Virgo.
For the Chinese zodiac, Lunar New Year has always passed by August 4, so the animal is simply the one for the birth year. Well-known people born on August 4 include Barack Obama (1961), Louis Armstrong (1901) and Percy Bysshe Shelley (1792).
