Most astrology is passive — it reads a moment you didn't choose. Electional astrology is active: you choose the moment. If you can pick when to sign the contract, launch the product, or marry, electional technique selects the chart most favourable to the venture's success.

The premise is the same as natal astrology: the chart of a beginning describes the life of the thing begun. A business launched under a strong Jupiter, with a dignified Ascendant lord and a well-placed Moon, inherits something of that sky. A marriage chart with Saturn squaring the 7th house lord carries that difficulty into the partnership. The chart is the seed; the venture grows from it.

You cannot choose the perfect moment. Electional is the art of the best available window.

The core rules

✦
Strengthen the planet and house of the venture
Identify the house that governs the venture (7th for partnerships, 10th for career launches, 2nd for financial matters) and its ruling planet. Place the ruler in dignity and make it angular if possible.
✦
Put a benefic on an angle
Jupiter or Venus on the Ascendant, MC, or Descendant is a strong positive indication. The Ascendant lord strong and dignified serves the same function.
✦
Keep the Moon strong and in a good aspect
The Moon governs flow, adaptability, and the venture's day-to-day operation. Moon in good dignity (exaltation or domicile), not combust, and separating from a benefic or applying to the Ascendant lord — these are good omens.
✦
Avoid void-of-course Moon for new beginnings
A void-of-course Moon — making no further aspects before leaving its sign — tends to produce ventures that come to nothing, or that simply fail to develop as intended.
✦
Respect Mercury retrograde for contracts and communications
Mercury retrograde is not universally harmful, but signing contracts, launching communications-dependent ventures, or making agreements during Mercury retrograde tends toward revision, misunderstanding, or reversal.

The constraint reality

Electional astrology is the art of the best available window, not the ideal one. The ideal chart rarely coincides with practical constraints — the venue is booked, the deadline is fixed, the other party won't wait. The electional astrologer works with what is available: within the range you can act, which window is least harmful and most supportive? That is the answer electional provides.

Worked example: electing a business launch

Suppose you want to launch a small consulting practice and have a two-week window in which to go public — announce the service, start taking clients, publish the site. The relevant house is the 10th (career, public activity, reputation). Its ruler, determined by whichever sign occupies the 10th in the elected chart's Ascendant, is your target planet to strengthen.

Working through the available dates: you want a day when the Moon is waxing (increasing, associated with growth and new beginnings), not void-of-course, applying to a trine or sextile with Jupiter. You want the 10th-house ruler in good dignity — in its domicile or exaltation, or at least in the sign of a friendly planet. You want a benefic — Venus or Jupiter — angular if possible: rising, culminating, or on the Descendant. Mercury, which governs communication and commerce, should not be retrograde for a communications business.

The result is rarely a perfect chart. More often you identify two or three candidate dates that satisfy the most critical conditions, then choose the one that best satisfies the most conditions simultaneously. The electional astrologer's skill is in ranking priorities: for a business launch, the condition of the 10th-house ruler is more important than the exact Moon phase; the absence of malefics on the Ascendant matters more than perfect Jupiter placement. You work the hierarchy.

Worked example: contract signing

Contract signings involve the 3rd house (documents, agreements of the everyday kind) or the 7th (formal legal agreements, business partnerships). Mercury must not be retrograde. The Moon must not be void-of-course — a void Moon on a signature tends toward the contract coming to nothing, or requiring complete renegotiation. Both parties should be represented sympathetically: the 1st house describes you; the 7th house describes the counterparty. A malefic on the 7th Descendant or ruling the 7th in debility is a signal that the other party will prove difficult to work with.

For a contract that involves a long-term commitment — a lease, a publishing deal, a partnership agreement — the Sun's placement matters too. The Sun applies to a fixed sign or is received by a strong fixed ruler if you want the agreement to last.

Weighting competing considerations

The tradition offers a rough priority order when factors conflict. The Ascendant and its ruler describe the venture and its general vitality — this is almost always the first priority. The house and ruler relevant to the specific matter (10th for career, 7th for partnership, 2nd for money) is the second priority. The Moon is the third priority: it governs flow, the day-to-day, and the chain of events that follows the election. Minor considerations — specific dignities, applying aspects of secondary planets — come last.

When you cannot satisfy all conditions, satisfy them in priority order. A launch with a strong Ascendant and strong 10th-house ruler, even with a merely adequate Moon, will usually outperform a launch with a beautiful Moon but a weak Ascendant. The exception is the void-of-course Moon: that is close to a veto condition for any new beginning, and it rarely worth accepting regardless of how strong everything else is.

Work the hierarchy. A strong Ascendant with an adequate Moon beats a beautiful Moon with a weak Ascendant.
