Free Lot of Marriage Calculator

The Lot of Marriage (also called the Lot of Union) is a calculated point in Hellenistic astrology that reveals how committed partnership operates in your chart. It is derived from Venus (the planet of attraction, affection, and the desire for union) and Saturn (the planet of commitment, duration, and structural bonds), connecting the impulse to love with the capacity to sustain a relationship over time.

Unlike most Hermetic lots, the Lot of Marriage has two traditional formulas. Vettius Valens, the primary ancient source, assigned the first formula (Ascendant + Venus - Saturn) to male nativities and the second (Ascendant + Saturn - Venus) to female nativities. This calculator shows both results, allowing you to examine the full picture of how partnership themes manifest in your chart.

Venus and Saturn may seem like an unlikely pair, but their combination captures the full arc of committed partnership. Venus supplies the attraction, the pleasure of companionship, and the desire to share life with another person. Saturn supplies the structure, the willingness to endure difficulty for the sake of the bond, and the capacity for loyalty that outlasts initial infatuation.

A marriage that is all Venus (pleasure without commitment) dissolves when difficulty arrives. A marriage that is all Saturn (duty without affection) endures but starves. The Lot of Marriage shows where these two forces meet in your chart, revealing the particular balance of desire and obligation that defines your approach to lifelong partnership.

The Lot of Marriage is closely related to the Lot of Eros, which represents desire, passion, and the raw attraction that draws people together. Where Eros describes what you want and who you are drawn to, Marriage describes what you commit to and how you sustain a bond over the long term. Together they map the full spectrum of intimate relationship, from initial spark to enduring union.

Studying both lots reveals whether your desires and your commitments align or pull in different directions. When Eros and Marriage share a sign or house, passion and commitment reinforce each other naturally. When they occupy different signs, the challenge is integrating what attracts you with what sustains you. Calculate all the lots with the Arabic Parts Calculator to see the full picture.
