Annual profections.

A Hellenistic timing technique. Each birthday advances the activated whole-sign house by one — at age zero you start in the 1st (the sign of your Ascendant), age one moves to the 2nd, and so on. At twelve you cycle back to the 1st. The traditional ruler of whichever sign holds the activated house becomes the Lord of the Year — the planet whose natal placement, current transits, and dignities tell you the topic and tone of the year.

Profections are defined on whole-sign houses by tradition — Valens, Maternus, the entire Hellenistic transmission. Modern systems like Placidus or Koch can give you wonky house cusps; profections require that house and sign indices match. So if your Ascendant is 27° Cancer, your 1st house IS Cancer, your 2nd house IS Leo, and the rest follow. It's the cleanest house system there is and the one your year is computed against.

The Lord of the Year is the traditional ruler of whichever sign holds your activated house. Mars rules Aries and Scorpio; Venus rules Taurus and Libra; Mercury rules Gemini and Virgo; Moon rules Cancer; Sun rules Leo; Jupiter rules Sagittarius and Pisces; Saturn rules Capricorn and Aquarius. The lord's natal house, sign, and dignity all colour the year. Watch its transits especially carefully — when the Lord of the Year stations, conjuncts a malefic, or perfects an aspect to a sensitive natal point, the year tends to mark a hinge there.

Inside an annual profection, each ~30-day window starting from your birthday activates the next whole-sign house in turn. So if you're in a 7th-house year (relationships, contracts, the other), the second month moves to the 8th (shared resources, depth), the third to the 9th (voyage, learning), and so on around the wheel. The Lord of the Month is the ruler of the monthly profected sign — same logic as the annual lord, scaled down.

A solar return is a chart cast for the moment the Sun returns to its natal degree each year — a fresh natal-shape cast for the year ahead. Profections are simpler: they don't cast a new chart, they just advance the activator inside your existing natal. Hellenistic practice often combines them: the profected house tells you the topic, the solar return tells you the live geometry around that topic, and current transits tell you the timing of contacts.

The Hellenistic timing techniques our paid Calibrate tool uses internally — profections, zodiacal releasing, secondary progressions, solar arc — are mathematical procedures. The compute is free. What we charge for is interpretation grounded in the calibration of which method actually fits your life. So we give the calculator away; the practitioner read in /astrology/calibrate is what you'd hire someone to do.

Profections are exact — the whole-sign rule means there's no orb question. Your birthday is the hinge: the year that begins on your birthday lasts until the next birthday, and inside it the monthly cycle starts over. Hour and minute of birth don't change the annual profected sign; they only matter for the natal chart's Ascendant — and your Ascendant determines the entire house ladder.
