The Sun crosses the small arc of Aries from Apr 19 to May 14. The ram's symbolism gives this band its initiating, first-to-move quality. There is an appetite for a fresh start and a willingness to act before the conditions are perfect. Courage here takes the practical form of making the first attempt.

Read this band as raw initiative looking for a clean target. The work is aim more than nerve. Aries rarely hesitates about whether to act, so the growth edge is the brief contact with reality before the charge, the moment that turns force into direction rather than friction.

Taurus is one of the wider ecliptic constellations, and the Sun moves through it for more than five weeks, anchored by the red eye of Aldebaran. Its sidereal season runs from mid-May into the solstice. Patience and an appetite for the concrete shape the reading, with a preference for work whose value can be felt and tested.

This is the part of the sky that builds slowly and keeps what it makes. It values sensory pleasure and the security of a thing you can hold. The shadow is inertia: holding a position past its usefulness because moving costs comfort. Worth here is something you cultivate rather than seize.

The Sun crosses Gemini from Jun 21 to Jul 21. Castor and Pollux mark the heads of the Twins, north of the Sun's path. The paired figure suggests exchange and a curiosity that sharpens through contact with another mind. Conversation gives an idea something to push against, so a question can be more useful than a settled answer.

This band connects ideas and passes them on. It thinks by talking and learns by sampling widely. The strength is range and adaptability; the cost can be a thin contact with any one thing. Gemini does its best work when curiosity lands somewhere long enough to become understanding rather than a stack of open tabs.

Cancer is a faint, narrow constellation, and the Sun clears it in about three weeks from late July into August. Its short stretch of the ecliptic gives a sidereal Cancer Sun a relatively small span of birthdays. The Crab's shell suggests a protected interior, with sensitivity to who belongs inside and what needs to stay outside.

Read this as the instinct to make a safe inside and tend what lives there. Care gives a sense of belonging, while memory helps sustain it. The protective reflex is the gift and the trap: the same shell that keeps the soft thing safe can keep it hidden. Cancer grows by choosing when to open the door.

The Sun crosses Leo for more than five weeks from August into mid-September. Regulus marks the base of the Sickle, the curved pattern that outlines the Lion's head and chest. Warmth and expressive confidence shape this reading. There is satisfaction in making a generous gesture visible and giving others something they can gather around.

This is the part of the sky that wants to give heat and be seen giving it. It leads through presence and generosity, and it needs an audience the way a fire needs air. The shadow is performance for its own sake. Leo is at its best when the warmth is offered first and the recognition follows rather than the other way around.

Virgo is the widest constellation on the ecliptic, and the Sun spends about six and a half weeks crossing it, longer than in any other constellation. The long passage runs from mid-September to the end of October. This reading values useful work and the patience to learn a craft through repeated attention to its details.

Read this band as the drive to refine, to make a thing correct and useful. It serves through skill and close attention to detail. The width of the constellation suits the placement: there is a lot of ground to work, and the temptation is to keep adjusting past the point of done. Virgo grows by letting good enough be finished.

The Sun passes through Libra from the end of October into late November. Its brightest stars still carry the old name of the Scorpion's claws, although the figure is now read as the Scales. The balance-seeking quality centers on relationship and a close comparison of each person's needs and contributions. A fair arrangement has to hold for both.

This is the part of the sky that holds two sides at once and looks for the fair arrangement between them. Proportion matters, and a choice deserves consideration. The shadow is the deferred decision, balance used as a way to avoid committing. Libra matures when weighing becomes a path to a decision rather than a substitute for one.

The Sun spends only about seven days in Scorpius before crossing into Ophiuchus. Antares marks the Scorpion's red heart, while its long curved tail extends well south of the ecliptic. A sidereal Scorpius Sun belongs to a narrow band of late-November births. The figure's intensity suggests a sustained interest in what lies beneath an easy explanation.

Read this as concentrated intensity, the instinct to go all the way into a thing or leave it alone. It works through focus and the willingness to sit with what others avoid. That depth can sustain demanding work, but it can also turn inward as suspicion or a need for control. The useful question is where such close attention is worth the effort.

The Sun crosses Ophiuchus from Nov 30 to Dec 18, between Scorpius and Sagittarius. The Serpent Bearer is associated with Asclepius in Greek myth, the healer who learned to bring back the dead. His serpent connects knowledge with renewal. In a symbolic reading, the figure suggests a willingness to work with difficult experience and learn something useful from it.

Ptolemy compares the constellation's bright stars with Saturn and, to a lesser degree, Venus. A modern reading of this band draws on the Serpent Bearer's task of handling a powerful creature without being overcome by it. Depth of knowledge matters, along with the judgment to use it carefully. The tendency toward difficult or hidden subjects becomes useful when understanding can be put into practice.

The Sun crosses Sagittarius from Dec 18 to Jan 20. Its brightest stars form the Teapot near the direction of the galactic center. The Archer's aimed arrow suggests purposeful exploration, with attention fixed on something farther away. The reading favors a wide perspective and a willingness to look beyond the immediate task for a reason to pursue it.

Read this band as the reach for meaning past the immediate, the arrow loosed at a distant mark. Exploration gives conviction something to test itself against. The shadow is the conviction that outruns the evidence, the answer announced before the question is understood. Sagittarius does its best work when the search stays honest enough to be corrected by what it finds.

Capricornus, the faint sea-goat, takes the Sun from late January into the middle of February. Structure and patience give this reading its direction. A distant goal becomes workable when effort has a clear order, and the ability to keep going matters as much as the ambition that began the work.

Read this as the discipline that builds toward a summit over time. Taking responsibility calls for endurance, with respect for what is earned rather than given. The shadow is the climb that forgets why it started, status pursued as its own reward. Capricornus matures when the mountain is chosen on purpose and the cost is paid with open eyes.

The Sun passes through Aquarius from mid-February into March, through the figure of the Water Bearer pouring his stream toward the Southern Fish. This reading favors a broad perspective and an interest in how a group works. Some distance from an immediate concern can make a pattern easier to see, especially when personal loyalties complicate the view.

Read this band as the step back that sees the pattern, the loyalty to an idea or a group over the immediate and personal. Originality can come from holding to a principle long enough to question an accepted arrangement. The shadow is the distance that becomes disconnection, the principle held against the actual people in front of you. Aquarius grows when the wide view stays warm.

Pisces is a wide, dim constellation, and the Sun spends more than five weeks crossing it from Mar 12 to Apr 19, including the March equinox. The fishes' shared cord suggests connection even when their attention pulls in different directions. Softness and permeability shape this reading, with a readiness to feel another person's experience as close to one's own.

Read this as the edge between self and everything else thinning out. Empathy and imagination depend on a sensitivity that can take in more than it can always sort. The shadow is the boundary that dissolves too far, escape mistaken for transcendence. Pisces does its best work when the openness is given a form to flow through rather than left to flood.
