Four times a year Mercury doubles back on its own path. Every week the Moon pulls into a new shape. And every few months the sky marks a moment that astrologers have tracked for thousands of years: an eclipse, a sign change, a cycle closing. This guide walks through every event that shows up in your alerts — what is actually happening in the sky, what it has traditionally meant, and how to use the signal on your chart or in your day.

Mercury Retrograde

At a glanceAbout 3 weeks · 3–4 times a year · Earth overtakes Mercury on the inside of its orbit

From Earth's perspective, Mercury appears to slow, stop, and move backward against the stars for about three weeks, three or four times a year. It isn't really reversing. Earth and Mercury are just moving at different speeds, and the geometry creates the illusion. The planet is actually at its closest point to Earth during this phase.

Astrologers link Mercury retrograde to a review phase for anything Mercury rules: communication, short trips, contracts, devices, decisions. Robert Hand describes it as a cycle where the mind turns inward and reconsiders. Bernadette Brady reads it as a time to finish what's already started rather than launch new projects.

Practical takeawaytreat the three weeks as a review, revise, and reconnect window. Back up files, reread contracts before signing, and expect old conversations or old contacts to resurface. Don't cancel your life; just build in a margin for second drafts.

Venus Retrograde

At a glanceAbout 40 days · every ~18 months · tracked since Mesopotamia

Venus retrogrades roughly every 18 months for about 40 days. Like all retrogrades, it's an optical effect of Earth overtaking Venus on the inside of its orbit. Mesopotamian observers were already tracking this cycle thousands of years ago; the cuneiform Venus Tablet of Ammisaduqa records her movements in detail.

In traditional astrology Venus rules love, money, values, and aesthetics, so Venus retrograde is read as a time when those themes get revisited rather than advanced. Steven Forrest frames it as a period where the psyche reexamines what it actually wants from relationship and pleasure, often surfacing unfinished business with past partners or old financial choices.

Practical takeawaynot ideal timing for weddings, major purchases, new relationships, or dramatic makeovers. Good timing for repairing an existing relationship, revisiting a creative project you abandoned, or rethinking a spending pattern.

Mars Retrograde

At a glance10–11 weeks · every ~2 years 2 months · longest of the three

Mars retrogrades about every two years and two months, lasting roughly ten or eleven weeks. It happens when Earth, on its faster inner orbit, passes Mars. Of the three personal retrogrades, this is the longest, and often the most felt, because Mars governs how we act on desire.

Traditional astrology treats a Mars retrograde as a cycle where assertive action gets complicated. Energy feels blocked, plans stall, or the effort required doubles. Robert Hand notes that frustration is the usual signal: what normally flows forward now meets resistance.

Practical takeawaynot the moment to pick a fight or launch an aggressive campaign. It's a good moment to examine how you pursue goals, where your anger actually points, and what you've been forcing that maybe shouldn't be forced. Train, refine, rethink your approach, and save the offensive push for the direct phase that follows.

New Moon

At a glanceEvery ~29.5 days · Sun–Moon conjunction · the sky goes dark

At the new moon, the Moon sits between Earth and the Sun, so its lit side faces away from us and the sky goes dark. Sun and Moon share the same zodiac degree for a few hours at the exact conjunction.

Astrologers read the new moon as the start of the lunar cycle, a seeding moment. The Sun represents conscious purpose and the Moon represents feeling and instinct, and at the new moon they are aligned. Whatever sign the new moon falls in gives the month its thematic flavor.

Practical takeawaygood timing for intention-setting, starting something small and personal, or reorienting. The energy is quiet rather than explosive; new moons are for planting seeds, not harvesting. If the new moon falls near a planet or angle in your natal chart, the theme is especially personal.

First Quarter Moon

At a glance~7 days after New Moon · Sun–Moon square · half-lit, waxing

About a week after the new moon, the Moon reaches a 90-degree angle to the Sun and we see half of it lit. The square aspect between Sun and Moon defines this phase.

In the lunar cycle this is the action phase. Whatever was seeded at the new moon now meets its first real test. Dane Rudhyar, who wrote extensively on lunar phases, described this as a "crisis in action": a point where effort and resistance are both required for the seed to become something real.

Practical takeawayexpect a push. The first quarter moon is a natural time to address obstacles rather than hope they disappear. If a project or intention has been drifting since the new moon, this is the moment to commit, adjust, or confront what's blocking it. Things that refuse to move here often need to be released.

Full Moon

At a glanceEvery ~29.5 days · Sun–Moon opposition · fully lit

At the full moon, Earth is between the Sun and Moon, so the Moon is fully lit from our vantage point. Sun and Moon sit in opposing zodiac signs at the exact opposition.

The full moon is the culmination and illumination point of the cycle. Whatever was seeded two weeks earlier becomes visible, sometimes as fruition, sometimes as a contradiction that needs resolving. The opposition between Sun and Moon often shows up as a tension between two sides of life: conscious goal versus emotional need, work versus home, self versus other, depending on the signs involved.

Practical takeawaywatch what surfaces. Full moons tend to bring feelings, information, or situations into clear view. Good timing for honesty, completions, and the kind of conversations you've been putting off. Major decisions made at the full moon are often colored by heightened emotion, so give them a day or two.

Last Quarter Moon

At a glance~7 days after Full Moon · Sun–Moon square · half-lit, waning

A week after the full moon, the Moon forms the closing 90-degree square to the Sun. We see half of it lit, but a different half than at the first quarter, and the waning phase is now well underway.

Traditional lunar-phase astrology treats this as a crisis of consciousness, a point where the meaning of the cycle is digested. What the full moon revealed is now processed, integrated, or let go. Dane Rudhyar called it the "reorientation" phase.

Practical takeawaya natural release point. Tie off what the cycle actually produced, and be honest about what didn't work. Useful timing for finishing tasks, closing projects, clearing out, or having reflective conversations. Starting something brand new here tends to feel uphill, because the lunar energy is descending toward the next new moon.

Sun Enters a New Sign

At a glanceEvery 30–31 days · ~1° per day · cardinal ingresses mark the seasons

The Sun moves through the zodiac at about one degree per day, so every thirty or thirty-one days it crosses from one sign into the next. The Sun's ingress into Aries marks the vernal equinox in the Northern Hemisphere, the ingress into Cancer marks the summer solstice, and so on through the year's cardinal points.

A Sun ingress shifts the seasonal flavor of the month. The sign the Sun enters sets the tone for the next four weeks of solar energy: identity, vitality, and what's being brought into the light. Solar ingresses into the cardinal signs (Aries, Cancer, Libra, Capricorn) are historically the most emphasized, because they mark the equinoxes and solstices.

Practical takeawaynotice which house of your natal chart the Sun is entering. That area of life, whether it's work, relationships, home, or finances, gets a month of focus and attention.

Venus Enters a New Sign

At a glance3–4 weeks per sign when direct · 8-year pentagram cycle

Venus changes signs roughly every three to four weeks when moving direct, though she can linger in a single sign much longer when retrograde. Her full synodic cycle traces the famous eight-year pentagram pattern across the zodiac.

Since Venus rules how we relate, what we enjoy, and what we value, her ingress shifts the flavor of those themes. Venus in Taurus feels stable and sensual; Venus in Gemini is curious and talkative; Venus in Scorpio is intense and selective. The sign Venus occupies colors the social and aesthetic mood of the weeks she spends there.

Practical takeawayuseful for timing. Venus in an earth sign favors durable purchases and slow romance; in an air sign, connections and conversation; in a water sign, intimacy; in a fire sign, bold expression. Check which house Venus is transiting in your own chart to see where the softness lands.

Mars Enters a New Sign

At a glance6–7 weeks per sign · full cycle ~2 years · up to 6 months if retrograde sits in the middle

Mars spends about six or seven weeks in each sign when moving direct, but can linger for six or seven months in a single sign when a retrograde falls in the middle of that transit. His full zodiac cycle takes about two years.

Mars rules drive, assertion, anger, and how we go after what we want, so his ingress is felt as a change in action style. Mars in Aries is fast and direct; Mars in Libra is strategic and relationally negotiated; Mars in Capricorn is disciplined and long-range; Mars in Pisces is indirect and often confused about its target. Robert Hand describes Mars's sign as the instrument through which raw desire expresses itself.

Practical takeawayadjust how you push. The same goal may need a different tactic depending on where Mars is. Check the house Mars is transiting in your chart to see where the energy concentrates.

Solar Eclipse

At a glanceNew Moon near a lunar node · 2–5 times a year · arrives in pairs or triples

A solar eclipse is a new moon that occurs near the Moon's north or south node, the two points where the Moon's orbit crosses the ecliptic. When the alignment is close enough, the Moon blocks some or all of the Sun's disk for observers on Earth. Eclipses come in pairs or triples, about six months apart, along a slowly shifting axis of signs.

In astrology, solar eclipses are treated as amplified new moons. Traditional sources, including Bernadette Brady's detailed work on eclipses, frame them as doorways: moments where the ordinary cycle of the Sun and Moon is interrupted and something new is introduced, often touching themes tied to the eclipse's sign axis.

Practical takeawaytake them seriously but don't dramatize. If a solar eclipse lands near a planet or angle in your natal chart (within a few degrees), pay attention to that area of life over the following months. Otherwise, treat the eclipse as a potent new-moon seed.

Lunar Eclipse

At a glanceFull Moon near a lunar node · pairs with the solar eclipse seasons

A lunar eclipse is a full moon that occurs near the lunar nodes, so that Earth's shadow falls across the Moon. The Moon can dim, redden, or go fully dark for the duration. Like solar eclipses, they arrive in seasons rather than singly.

Lunar eclipses are treated as amplified full moons. Because the full moon's opposition is already a revealing and sometimes disruptive aspect, an eclipse can feel like it turns the volume up. Brady's eclipse work emphasizes completion, release, and sometimes an emotionally charged revelation of something that had been hidden.

Practical takeawaywatch for endings and emotional truths. Lunar eclipses often coincide with the conclusion of a chapter, especially if they land near sensitive points in your natal chart. Give yourself some buffer around the exact date; eclipses tend to have a longer window of influence than ordinary full moons. Avoid major impulse decisions at peak.

Void-of-Course Moon

At a glanceMany times a month · minutes to hours · Moon between its last aspect and the next ingress

The Moon is "void of course" during the interval between its last major aspect to any other planet in a given sign and the moment it crosses into the next sign. Because the Moon moves faster than every other body, this gap happens many times a month and can last anywhere from a few minutes to many hours.

Traditional horary astrology treats a void-of-course moon as a period where "nothing will come of the matter." The Moon is considered temporarily disconnected from the planetary network, so initiatives started during a void tend to fizzle or stall.

Practical takeawaya good window for routine, rest, tidying, or internal work. Not ideal for signing contracts, launching something new, or making decisions you want consequential results from. If you must act during a void, keep expectations modest; the planning you do now may need to be redone once the Moon enters the next sign.
