Solar Return Chart — Discover Your Year Ahead with AI

Every sign spans thirty degrees and splits into three ten-degree decans, each with its own ruler under the Chaldean order and its own Minor Arcana card. Where you fall inside Aries is a real distinction, and it is the first thing a solar return chart makes visible.

Mars is the fastest of the two malefics and the only traditional ruler whose whole character is about initiation rather than maintenance. In a solar return that matters in a specific way: the chart is a year, and Mars describes what you will spend that year pushing at. Where it sits by house in the return is usually the most literal reading available in the whole chart — not a mood but an activity, and one you will recognise within weeks of the birthday rather than in retrospect.

Mars also sets an unusual rhythm for an Aries year. It stations retrograde roughly once every two years, so most solar returns you will ever have contain no Mars retrograde at all — and then one does, and that year behaves differently from the eight or nine around it. This is the opposite of a Mercury-ruled sign, where the ruler reverses three times a year and the reversal is ordinary. For you it is rare enough to be worth dating in advance, which is what the window below is for.

The three decans of Aries are ruled by Mars, the Sun and Venus, and they are not variations on a theme. A first-decan Aries carries Mars twice — as sign ruler and as decan ruler — and it is the only ten-degree stretch of the zodiac where the planet of initiation is doubled. That is the configuration most of the popular writing about Aries is actually describing, which is why the description fits some Aries and not others.

The second decan replaces the second Mars with the Sun, and the difference is between starting things and being seen doing them; the Six of Wands sits here, and it is a card about public recognition rather than about the fight. The third hands the decan to Venus, which is the classical opposite of Mars, and produces the Aries nobody writes about: the one whose initiative shows up in relationships and aesthetics rather than in conflict. When a solar return reading feels wrong for you, this is the first place to look.

The tropical zodiac is measured from 0° Aries, and 0° Aries is the vernal equinox itself — the moment the Sun crosses the celestial equator going north. Your sign does not begin near the equinox; it begins at it, by definition. Everything else on this site is measured from that point, including every degree in the tables below. It also means your solar return always falls in the first days of astronomical spring in the northern hemisphere, which is a small practical fact with a real consequence: your year is dated from the same moment the calendar year is measured against, so a solar return chart and a year-ahead forecast line up more neatly for you than for anybody else.

Your solar return falls between the third week of March and the third week of April, which in the northern hemisphere is the start of the working spring and in the southern the start of autumn. That is worth knowing because a solar return chart is most useful read at the beginning of the year it describes, and yours arrives at a moment when most institutions — financial years, school terms, project cycles — are also turning over. The practical effect is that an Aries year tends to be easy to act on: the chart and the calendar agree about when the new thing starts.

The decan dates above give the exact ten-day window your own degree falls in, computed rather than rounded. That matters more than it sounds: the difference between a 29° Aries and a 1° Taurus birthday is one day and an entirely different chart, and the boundary moves by up to a day between years. If you were born within about thirty-six hours of a sign boundary, the birth time is not optional and a noon assumption will sometimes give you the wrong sign entirely.

Look at the return Mars before anything else, including before the return Ascendant. For most signs the Ascendant is the first thing worth reading; for Aries the ruler is more informative, because a Mars in the tenth house and a Mars in the fourth describe two years that will not feel remotely alike, whatever the rising sign says. Its house is the answer to "what am I going to be pushing at", and it is usually right.

The second thing is whether Mars is retrograde at your return or stations during the year. Because it happens so rarely, a retrograde Mars year is genuinely unusual for you, and the useful reading is not that everything stalls but that the initiative turns inward — the project you push at is one you have already started. The dates below tell you whether this applies to the year you are about to have.

2 eclipses fall in Aries between 2024 and 2030. An eclipse near one of your own degrees is the single most datable thing in a year, which is why the exact positions are printed rather than described.

• April 8, 2024Solar eclipse at 19° Aries
• March 29, 2025Solar eclipse at 8° Aries

Aries has carried the nodal axis recently and is handing it on. The eclipses listed here are the ones whose degrees you can compare against your own Sun: anything within a few degrees is worth dating, and anything further away is a fact about the sky rather than about you.

Your ruler stations retrograde 3 times between 2024 and 2030 — about 0.5 periods a year. That rate is a fact about orbital geometry rather than about you, and it is the single biggest difference between one sign and another here: a Mercury-ruled sign sees its ruler reverse roughly three times a year, a Mars-ruled one waits about two years between.

The first of those inside the measured span runs from December 6, 2024 to February 24, 2025 — real station dates you can check against any ephemeris, not an estimate.
