Secondary progressions and your progressed Moon, explained

Secondary progressions move your birth chart forward in time with one simple key: each day after your birth stands for one year of your life. The planets' positions 30 days after you were born are read for age 30, the positions 31 days after birth for age 31, and so on. Astrologers read progressions as a slow inner timeline, and the part most people follow is the progressed Moon, which moves into a new sign every two to two and a half years.

TL;DR: Progressions read the sky N days after your birth for age N. The progressed Moon moves about 12 to 15° a year, changes sign about every 2.3 years and goes round the zodiac in about 27 years; the progressed Sun moves about 1° a year and changes sign roughly every 30 years. Tradition reads them as stages of inner development, not as events.

What are secondary progressions?

Your birth chart records the planets at the moment you were born. Secondary progressions let the planets keep moving: they take their real positions in the days after your birth and assign each day to one year of life. The first 24 hours after birth stand for your first year of life, the sky 20 days after birth for age 20, 31 days after birth for age 31. The word "secondary" sets them apart from primary directions, an older technique built on the daily turning of the sky.

Here is how that works for a fictional person born in New York on July 4, 1995, at 9:20 a.m., the same chart we use in our transits example. On November 10, 2026, they are 31.35 years old. Their progressed chart for that day is the sky 31.35 days after their birth: August 4, 1995, at about 5:48 p.m. New York time. In that sky the Sun stands at 12.0° Leo and the Moon at 22.1° Scorpio, so those are this person's progressed Sun and progressed Moon on November 10, 2026.

Numato's calculator works out a progressed chart in three steps:

• The year key. One day of planetary motion equals one tropical year of 365.24219 days, the time from one spring equinox to the next. Any calendar date maps to an exact moment after your birth.
• The planets. Their real positions at that moment, from the NASA JPL ephemeris (DE440), the same data as your birth chart.
• The angles and houses. The Naibod method: the sidereal time of your birth, which fixes the Midheaven, moves on by the Sun's average daily motion, 0°59′08″, for each year of life, and the Ascendant, MC and house cusps are worked out from it for your birthplace. In the New York example, the MC moves from 20.5° Taurus at birth to 19.9° Gemini by November 2026, and the Ascendant from 26.9° Leo to 21.3° Virgo.

How fast do progressed planets move?

Because a day becomes a year, a progressed planet covers in one year of your life the distance the real planet covered in the matching day after your birth. The speeds are very uneven. Here is what Numato's engine shows for the New York example, from birth to November 10, 2026:

The slow planets moved backward here because they were retrograde in the weeks after this person's birth. A planet that turned retrograde or direct in the weeks or months after a birth does the same in progression, at the matching age. Because Jupiter to Pluto barely shift, progressions concentrate on the Sun, Moon, Mercury, Venus and Mars, and so does the calculator's progression timeline.

The progressed Moon: a new sign every two years or so

The progressed Moon is the fastest-moving part of the progressed chart and the one astrologers follow most closely. Across the 123 years the calculator's timeline covers, the engine finds 54 sign changes for the New York example, between 1.98 and 2.54 years apart and 2.26 years apart on average, and a full round of the zodiac takes 27.2 to 27.4 years. The often-quoted "every two and a half years" is the upper end of that range: when the Moon was moving fast in the days after a birth, progressed sign changes come closer to every two years.

Progressed Moon sign changes, 2026–2035

Here are the progressed Moon's sign changes for the New York example and for a second fictional person, born in London on January 10, 1990, at 7:30 a.m. Dates are in the time zone of each birthplace and, as in the calculator, given as month and year:

The same rule gives different rhythms. In these years the New York example's progressed Moon changes sign every 2.0 to 2.2 years, the London example's every 2.2 to 2.5 years, because the real Moon was moving at a different speed in the days after each birth.

These dates depend on the birth time. The Moon moves about half a degree an hour, so a birth time one hour later moves every progressed Moon date about two weeks earlier. With 10:20 a.m. instead of 9:20 a.m., the New York example's progressed Moon enters Sagittarius on May 17, 2027 instead of June 2, 2027. Even four minutes shift it by about a day, which is why the calculator shows these changes by month.

About 27 years after birth, the progressed Moon comes back to its birth position, a moment sometimes called the progressed lunar return. For the New York example it was exact in September 2022, at age 27, and it comes round again in December 2049, at 54. Tradition reads it as the close of one long cycle of emotional needs and the start of the next.

The progressed Moon in each sign

In astrology the Moon stands for emotions and needs: what you need to feel safe. A progressed Moon sign is read the same way as a birth Moon sign, but for a stretch of about two years: what feels necessary, comfortable or pressing during that time. The house of your birth chart it is passing through shows the area of life where those needs come up. Here is the short version; each sign is described in full in our guide to the Moon in each sign.

When does the progressed Sun change sign?

The progressed Sun moves about 1° a year, so it spends around 30 years in a sign and changes sign two or three times by about age 80. Its pace depends on the season of birth, because the real Sun moves slowest in early July and fastest in early January. For the New York example, born in July, it moves 0.95° to 0.96° a year; for the London example, born in January, 1.01° to 1.02°.

In astrology the Sun stands for your sense of self: what drives you and where you want to be yourself. A new progressed Sun sign is read as a change of emphasis that lasts for decades. Your birth Sun sign still describes you; the progressed sign is read as adding a style that becomes more natural over the years. For the London example, the move from Aquarius (independence, ideas, community) to Pisces (empathy, imagination, gentleness) in 2029 is read as a gradual turn toward empathy and imagination, alongside the Capricorn Sun of birth.

Progressed Sun aspects last a long time. With the calculator's 1° orb, one aspect stays in orb for about two years: for the New York example, the progressed Sun squares the natal MC from August 2034 to September 2036, exact in September 2035. Tradition reads a square as two matters are in conflict and usually call for a decision or effort and the MC as career direction, so this stretch is linked with rethinking where work and goals are heading.

What is the progressed lunar phase?

The progressed Sun and Moon form a cycle of their own. Each time the fast progressed Moon catches up with the slow progressed Sun, there is a progressed New Moon, and the next one comes about 29.5 years later. In between, the angle between them passes through eight phases of 45°, each lasting about 3¼ to 4 years. This progressed lunation cycle was described by the astrologer Dane Rudhyar, and the calculator uses the same eight phases.

In the progressions result, the Planets tab lists the phase of the progressed chart as "Moon phase". For the New York example on November 10, 2026, it reads "First Quarter": the progressed Moon is 100° ahead of the progressed Sun.

The New York example's progressed New Moon fell in August 2018, at 4° Leo, at age 23, and the next comes in February 2048. The London example's fell in July 2006, at 6.6° Aquarius, and the next comes in January 2036. Rudhyar called the Waning Gibbous phase "disseminating" and the Waning Crescent "balsamic"; the calculator uses the astronomical names.

Progressions vs solar arc vs transits: what's the difference?

These three timing techniques are often confused. All of them compare something that moves with your birth chart; what moves, and how fast, is different.

The difference shows in the numbers. On November 10, 2026, the New York example's progressed Sun is 29.9° past its birth position. Solar arc directions move every point by exactly that arc, while progressions let each planet move at its own pace:

The progressed Moon has gone once round the zodiac and another 56°, while the solar arc Moon has moved 29.9°, like every other point. Astrologers who combine the techniques use solar arc to point to the year of a turning point, progressions to describe the inner stage, and transits to time the moment. Numato has a separate solar arc calculator that lists the directed points in aspect to your birth chart. How the planets in the sky move against your chart week by week is covered in our guide to transits, and a fourth tool, one chart for the year from birthday to birthday, is the solar return chart.

How to read your progressions, step by step

Read progressions like any chart: the planet says what, the sign how, the house where, and the aspect in what tone. Start with the fastest and most personal factors:

1. The progressed Moon's sign: which needs are in focus for these two-odd years (see the progressed Moon in each sign).
2. The birth chart house it is passing through: the area of life where those needs come up. A full round of the houses takes about 27 years, so the progressed Moon stays a little over two years in a house on average.
3. The progressed Sun: its sign is the long background, and a recent sign change marks a shift in emphasis.
4. The progressed lunar phase: which stage of the roughly 30-year cycle you are in.
5. Aspects to your birth chart: progressed Moon aspects stay in orb for just under two months, progressed Sun aspects for about two years. Tradition reads an exact progressed aspect as a time when the theme of the natal point comes to the fore and matures.
6. Transits and the solar return on top: progressions describe the inner background of the years; transits mark the moments within them.

Take the New York example in November 2026. The progressed Moon has been in Scorpio since April 2025, and at the end of September 2026 it crossed into the 4th house of the birth chart, reaching the IC exactly opposite the natal MC. The progressed Sun has been in Leo since 2014, and the progressed lunar phase turned First Quarter in January 2026. In March 2027 the progressed Moon squares the natal Ascendant, and in June 2027 it moves into Sagittarius.

How would tradition describe this? A Scorpio Moon describes a need for trust, honesty and deep connection (more in Moon in Scorpio), and the 4th house covers home, family and origins. Together they describe a couple of years in which family ties and a sense of home ask for honesty and depth. The First Quarter phase adds a stage of decisions and building. The square to the Ascendant in spring 2027 points to tension between these private needs and the way this person presents themselves and starts new things. From June 2027, the progressed Moon in Sagittarius is read as shifting the emphasis to freedom, purpose and room to explore. That describes an inner background, not a forecast of moving house or of any other event.

One practical note: the progressions result places this progressed Moon in the 3rd house, because it shows the houses of the progressed chart. Many astrologers read progressed planets against the houses of the birth chart instead. To do that, compare the progressed Moon's degree with the cusps in the Houses tab of the birth chart calculator.

What progressions can't tell you

We calculate planetary positions astronomically, from NASA JPL ephemeris data (DE440). What progressions mean comes from astrological tradition, explained here in plain language, and that tradition has limits:

• They don't describe events. A progressed Moon sign change or a progressed New Moon describes a gradual shift in what feels important, not what will happen or when.
• A date isn't a switch. The engine finds the moment of a sign change, but a new progressed sign is read as a slow shift over months, and the exact date depends on the birth time.
• They need an accurate birth time. One hour's error moves the progressed Moon's dates by about two weeks; without a time, the calculator leaves out the progressed angles and houses.
• A hard aspect isn't a verdict. A progressed square describes a stretch of effort and decisions, not a failure.
• They don't replace decisions based on facts. On money, work or family matters, facts and qualified advice should decide, not a progressed chart.

How to see your progressions in the calculator

Numato has two progression tools. Both need your birth date and place; an exact birth time adds the progressed angles and houses and makes the Moon dates precise.

1. Progressions: the chart for one day. Open the progressions calculator, enter your birth details and, under "When", pick a date in "Progressions for" (today by default). The result opens with the "Moment of the chart" card ("Progressions for November 10, 2026"), then the Big Three of the progressed chart (Sun, Moon and Ascendant), the chart wheel and the Planets, Aspects, Houses and Balance tabs. The Planets tab shows the progressed lunar phase as "Moon phase". The wheel and the Aspects tab show the progressed chart on its own, so the aspects listed are between progressed planets, not to your birth chart.
2. Progression timeline: your whole life. The progression timeline needs no date. The "Now" card lists the signs of your progressed Sun, Moon, Mercury, Venus and Mars today, each with the month it entered ("since Apr 2025"), plus the progressed aspects in orb right now. Below, "Decade by decade" lists the sign changes, such as "Progressed: Moon — sign change: Scorpio → Sagittarius" dated Jun 2027, and the aspects to your birth chart within a 1° orb, with month dates. The progressed Moon's aspects, the longest list, sit behind the "Show progressed Moon aspects" button.

Without an exact birth time, the timeline leaves out aspects to the Ascendant and MC and says so above the list. The calculator uses the tropical zodiac by default; you can switch to the sidereal zodiac in the settings.

Frequently asked questions

How do I find my progressed Moon sign?

Enter your birth date, time and place in the progression timeline. Its "Now" card shows the sign of your progressed Moon today and the month it got there, and the decade list shows when it moves on. For the exact degree on a chosen day, use the progressions result: the progressed Moon appears in the Big Three and in the Planets tab. For the New York example on November 10, 2026, it is 22.1° Scorpio.

How long does the progressed Moon stay in a sign?

Between about two and two and a half years, 2.3 on average, because the progressed Moon moves about 12 to 15° a year depending on how fast the real Moon moved in the days after your birth. In 2026–2035 the New York example's progressed Moon changes sign every 2.0 to 2.2 years and the London example's every 2.2 to 2.5 years, as the table of sign changes shows. All twelve signs take about 27 years.

What is the progressed lunar return at 27?

It is the moment the progressed Moon comes back to its birth position, about 27.3 years after birth: for the New York example in September 2022, at 27, and again in December 2049, at 54. Tradition reads it as the end of one long cycle of emotional needs and the start of the next, a time to notice which habits and needs still fit. It is a gradual stage, not an event, and its exact month depends on the birth time.

Do I need my exact birth time for progressions?

For the progressed Moon, angles and houses, yes. The Moon moves about half a degree an hour, so each hour of error shifts progressed Moon dates by about two weeks. Without a time, the calculator leaves out the progressed Ascendant, MC and houses, and the progressed Moon becomes a range: for the New York example on November 10, 2026, from 16.6° Scorpio to 0.7° Sagittarius, about a year's movement. The progressed Sun shifts by less than 1°.

Why do different sites show different progressions?

Usually because of the method for the angles or the birth data. Numato moves the angles with the Naibod method; some programs move the MC by the Sun's actual arc instead, which for the New York example on November 10, 2026 gives 20.4° Gemini instead of 19.9°. A different birth time or time zone moves the progressed Moon by days or weeks. The year length matters little: 365.25 days instead of 365.24219 changes the progressed Moon by under 0.01°.
