What is a profection year?
Annual profections are one of the oldest timing techniques in astrology, used by Hellenistic astrologers nearly two thousand years ago and revived in the last few decades through translations of their texts. They need no ephemeris for the year: the count is pure arithmetic on your birth chart.
What makes them useful is the lord of the year. Its placement in your birth chart, and what it does in the sky over the year, are read as the year's main thread, which is why astrologers who use profections watch that one planet's transits closely.
How the count works
One sign a year, starting from your Ascendant's sign, with whole-sign houses: the sign of the Ascendant is the 1st house, the next sign the 2nd, and so on.
Your age in completed years decides the house: age 0 is the 1st house, age 1 the 2nd, age 11 the 12th, and age 12 is the 1st again. So everyone is in a 1st house year at 0, 12, 24, 36, 48, 60, 72 and 84, a 4th house year at 3, 15, 27, 39 and so on, whatever their Ascendant. The Ascendant decides which sign each of those houses falls in, and so which planet is lord.
The lords are the seven traditional rulers: the Sun for Leo, the Moon for Cancer, Mercury for Gemini and Virgo, Venus for Taurus and Libra, Mars for Aries and Scorpio, Jupiter for Sagittarius and Pisces, Saturn for Capricorn and Aquarius. Uranus, Neptune and Pluto are not used, as in the tradition the technique comes from.
The year turns on your birthday. A birthday on 29 February moves to 28 February in common years.
Which house is your age?
The same for everyone: find your age to see which house your current year activates.

The lord of the year
The traditional reading of a year under each of the seven lords. Your result adds where your lord sits in your birth chart and what it does in the sky this year.
Leo
Sun
In a year ruled by the Sun, astrologers read the themes of visibility, vitality, purpose and the people with authority in your life. The Sun's placement and condition in your chart, and its passage through the year, describe how the year's light falls.
Cancer
Moon
In a year ruled by the Moon the themes are the body, the home, family, emotional needs and the ebb and flow of daily life. The Moon is the most changeable lord, and a Moon year is often described as fluid.
Gemini · Virgo
Mercury
In a year ruled by Mercury the themes are thinking, speaking, writing, trade, travel and connection. Mercury's retrogrades during the year are read as the points where those matters are reviewed or revisited.
Taurus · Libra
Venus
In a year ruled by Venus the themes are relationships, pleasure, beauty, money and what you value. It is traditionally a benefic year lord, though its placement in your chart says how easily its gifts arrive.
Aries · Scorpio
Mars
In a year ruled by Mars the themes are effort, conflict, courage, competition and the things you have to fight for. It is traditionally a malefic lord, read as a year that asks for action and rewards decisiveness.
Sagittarius · Pisces
Jupiter
In a year ruled by Jupiter the themes are growth, opportunity, teaching, faith and generosity. It is traditionally the greater benefic, and a Jupiter year is often read as expansive, sometimes more than is wise.
Capricorn · Aquarius
Saturn
In a year ruled by Saturn the themes are responsibility, structure, limits, time and endurance. It is traditionally the greater malefic, read as a year of work whose results last.
The twelve house years
What astrologers read each house year as being about. These are themes to notice, not events to expect.
1st house
A first house year, at 0, 12, 24, 36, 48, 60, 72 and 84, puts the profection back on your Ascendant, and your chart ruler becomes lord of the year. Astrologers read it as a year about you: the body, your direction, how you present, a fresh start of a twelve-year round.
2nd house
A second house year is read as a year of resources: money, possessions, earning and spending, and the values underneath them. It is often described as practical, a year for building or repairing a base.
3rd house
A third house year is read as a year of the near world: communication, writing, study, short journeys, siblings, neighbours and the routines of getting around. Information and conversation are the themes.
4th house
A fourth house year is read as a year of home and roots: family, parents, where and how you live, property, the private self. It is often a year in which something about home changes or needs attention.
5th house
A fifth house year is read as a year of creation and pleasure: children, romance, creative work, play, anything done for joy. Traditionally it is one of the good houses, a year of good fortune.
6th house
A sixth house year is read as a year of work and the body: daily routines, health, employment, the duties that fill a day. Traditionally it is a difficult house, and astrologers often describe it as a year of effort and maintenance.
7th house
A seventh house year is read as a year of others: partners, marriage, close collaborators, contracts, and open opponents. Whatever happens tends to happen through another person.
8th house
An eighth house year is read as a year of shared and borrowed things: other people's money, debts, inheritance, intimacy, endings that make room for change. Traditionally a difficult house, it is often described as a year of depth.
9th house
A ninth house year is read as a year of wider horizons: travel, higher study, teaching, belief, publishing, other cultures. It is often described as a year of looking further than usual.
10th house
A tenth house year is read as a year of public life: career, reputation, responsibility, being seen in the work you do. Traditionally one of the strongest houses, it is often a year of action and visibility.
11th house
An eleventh house year is read as a year of friends and allies: groups, networks, patrons, hopes for the future. Traditionally it is the house of good spirit and among the most fortunate years.
12th house
A twelfth house year, the last of the round, is read as a year of retreat: solitude, rest, hidden matters, what goes on behind the scenes. Traditionally difficult, it is often described as a year of closing things before the next first house year.
Monthly profections
The same count runs inside each year, one sign a month from your birthday: the first month is the year's sign, the second month the next sign, and so on. Each month has its own lord, read as a smaller thread within the year's. Your result lists the twelve months of your current year with their dates.
Profections and your solar return
Both techniques cover the same span, birthday to birthday, and they are often read together. The solar return chart shows the year's sky; the profection names which house and which planet to look at first.
A common approach is to find the lord of the year in the solar return chart: its house there, its aspects, whether it is angular. The solar return calculator shows the chart for any year.
Do you need a birth time?
Yes, for the usual method: the count starts from your Ascendant, and the Ascendant changes sign about every two hours. Without a birth time this calculator counts from your Sun sign instead, a variant some astrologers use, and says so on the result.
