From the point of view of predictive astrology, the birth chart of JK Rowling, born on July 31, 1965 in the county of Gloucestershire, in the southwest of England, is very easy to read. According to her sidereal chart, she was born in the Libra ascendant, the placement of the planets in her chart reads as follows: Ketu (dragon’s tail) in the second house, Scorpio; Saturn in the fifth house, Aquarius; Jupiter and Rahu (dragon head) in the 8th house, Taurus; Sun in the tenth house, Cancer; Venus, Moon and Mercury in the eleventh house, Gemini; Mars in the twelfth house, Virgo.

For the native of Libra, the ascendant Saturn is the most important planet, being the lord of the angle, fourth house, Capricorn: and the trinal fifth house, it becomes absolutely a functional benefit. His presence in the fifth, his daytime house, is only close to being in the sign of Libra, his exaltation. The placement of Saturn in his chart is truly first class.

Jupiter, the lord of the third and sixth houses, two weak positions for this ascendant, is a functional malefic. His placement in the eighth is excellent as he creates a vipareet raja yoga, which literally means ruling combination by reversal of negative effects (his relationship with Rahu has further weakened him). The third house, among other things, represents bad thoughts, placing the lord of him in the eighth will destroy bad thoughts and leave good ones behind, which is good for a career as a writer. Sixth house indications: fear, difficulties, enemies, ill health, debts will all have a similar fate, ie destruction.

Presence of the lord of the seventh house (spouse), Mars in the twelfth, the waste of the house, wandering far from the place of birth, loss, aptly describes his move from England to Portugal, his marriage in the year 28 (the year of Mars) and divorce nearly a year later.

The placement of the Sun, the lord of the eleventh house, and the arrangement of three auspicious planets, the Moon, Mercury and Venus in the tenth (Midheaven), interchanging position with the Moon is also excellent. The tenth placement (profession/occupation) is best for the Sun, as it gives it full directional strength. This royal planet and ruler of the zodiac grants immense fame to the native, its exchange with the Moon (another royal planet that represents the imagination, among other things) means fame through imagination.

The presence of three auspicious planets in the eleventh signifies three sources of income. The combination of the first (Venus meaning native), ninth (Mercury representing luck) and tenth (Moon, profession) lords having a mutual aspect of Saturn is creating a very formidable ruling combination: relationship between the lords of three angles (1st, 4th, 10th) and three trines (1st, this house is both an angular and trinal house, 5th and 9th) with exchange of 10th and 11th lords is the rarest of the rare.

Moon conjunction, profession, imagination; Mercury, writing, speech; and Venus, native, is obviously giving immense writing income.

But because of the bad placement of Mars, all of its good and bad planets are favorably placed, giving rise to a phenomenon called Harry Potter through JK Rowling.
