Welcome to the new year! One way to make 2021 better is to understand the astrology ahead and prepare accordingly. This guide lays out the key planetary movements and transits for the year so you can plan with intention.
After a tumultuous 2020, most of us are ready for renewal and steadier footing.
Recap: the astrology that shaped 2020
2020 was dominated by a powerful Capricorn stellium that brought Jupiter, Saturn, and Pluto together in Capricorn. Combined with additional planets in that sign, final eclipses along the Cancer–Capricorn axis, and retrogrades of the personal planets, it’s no surprise the year felt so pivotal for both individuals and societies.
With Capricorn and Saturn prominent, 2020 carried restrictive, disciplinarian energy. A brief move into Aquarius earlier in the year—Aquarius being the sign of groups and the collective—also influenced the pandemic-era restrictions that affected daily life.
Yet not all energy was contraction. Black Moon Lilith in Aries amplified protest, independence, and insistence on change. That assertive energy fueled demonstrations and a heightened awareness of injustices that many now want to address. Lilith’s later shift into steady Taurus suggests some of that resolve may become more pragmatic and values-driven.
By mid-December Jupiter and Saturn left Capricorn and entered Aquarius, aligning on December 21, 2020. That ushered in a focus on broader change and innovation—very fitting for the start of a new year.
Your 2021 Ultimate Guide to the Stars
2021 Astrology: Mercury Retrograde
2021 features the usual three Mercury retrogrades, and all occur in Air signs:
- Aquarius – January 30 to February 20
- Gemini – May 29 to June 22
- Libra – September 27 to October 18
Air signs rule communication, thought, and social interaction, so these retrogrades will especially affect how we express ourselves and relate to others. The Aquarius retrograde aligns closely with Jupiter and Saturn in Aquarius (Mercury conjunct Jupiter on February 14), bringing heightened attention to collective visions, technological and social reforms, and long-term plans.
The Gemini retrograde coincides with a Gemini–Sagittarius eclipse season and triggers the June 10 Gemini solar eclipse, offering opportunities for second chances and revisions. The Libra retrograde begins under a challenging angle to Pluto in Capricorn, warning of potential power struggles in relationships; it’s a period for improving fairness, diplomacy, and mutual respect.
2021 Astrology: Venus Retrograde
Venus turns retrograde in Capricorn from December 19, 2021 through January 29, 2022. This retrograde invites review of Capricorn themes: responsibility, ethics, and how we handle commitments. Relationships may be reevaluated—those that support growth and integrity will require renewed commitment, while one-sided or unhealthy connections may need to be reworked or released.
Venus retrogrades often reconnect people with past partners or prompt temporary breakups and reconciliations. This period favors diplomacy, mediation, and honest conversations about values and long-term needs.
2021 Astrology: Mars Moves Forward
Mars, which spent a large portion of 2020 in Aries (including a retrograde), leaves Aries on January 6, 2021 and continues forward through the year, ending in Sagittarius. With Mars no longer retrograde long-term, action becomes more straightforward and less encumbered by repeated delays or second-guessing.
Notably, Mars joins Uranus in Taurus on January 20, sparking energy for change that seeks practical stability. Actions taken under this influence tend to be researched, value-driven, and persistent—once a decision is made, it’s pursued with determination.
Eclipse Season 2021
After an exceptionally eclipse-heavy 2020, 2021 returns to the usual two eclipse seasons. The first includes a Lunar Eclipse in Sagittarius on May 26 and a Solar Eclipse in Gemini on June 10. These eclipses emphasize ideas, learning, travel (when possible), and pursuing passions—especially projects seeded around December 2020.
The second eclipse season brings a Lunar Eclipse in Taurus on November 19 and a Solar Eclipse in Sagittarius on December 4. The Sagittarius solar eclipse provides a final push for expansion, new initiatives, and adventurous planning, while the Taurus lunar eclipse highlights the groundwork and stability that will shape 2022. It’s a time to remove obstacles to security and strengthen what supports long-term confidence.
2021 Transits: Saturn Square Uranus
The main transit theme of 2021 is Saturn square Uranus, an on-and-off exact aspect throughout the year. Squares demand adjustment: Saturn stands for tradition and structure, while Uranus represents disruption and innovation. This tension asks us to dismantle outdated systems where needed and rebuild in ways that are practical and enduring.
Balance is essential. Avoid rigid resistance to change, but also steer clear of reckless, impulsive moves. Thoughtful, disciplined innovation will yield the best long-term results—particularly with Saturn and Jupiter active in Aquarius, a sign aligned with Uranus and collective progress.
Astrological Events for 2021: Jupiter & Neptune in Pisces
Jupiter spends most of 2021 in Aquarius but dips into Pisces from May 13 to July 28. During that window Jupiter harmonizes with Piscean themes—compassion, intuition, and spiritual sensitivity—while beginning an eventual larger partnership with Neptune that becomes more significant in 2022.
Expect increased empathy, creative inspiration, and opportunities to heal or release emotional baggage. This period supports compassion-based projects, charitable outreach, and exploration of the subconscious and spiritual practices that help you move forward with clarity.
2021 is a Year for Big Changes
In summary, 2021 brings a blend of challenge and opportunity. With Mercury retrogrades in Air signs, Venus retrograde bookending the year, Mars freeing up forward motion, eclipse activations, and the persistent Saturn–Uranus square, the year favors thoughtful transformation. Plan carefully, take measured risks where needed, and focus on building lasting structures that reflect new values and insights.
Track these transits as they unfold and use them to guide intentional change. Wishing you a purposeful and growth-filled year.
