ERA is a personal AI astrologer. It calculates your exact natal chart, progressed chart (who you are today, not just who you were born as), and planetary life cycles to give you strategic, personalized interpretations — not generic horoscopes based only on your sun sign.

How does ERA calculate my natal chart?

ERA uses your exact date, time, and place of birth to calculate the precise position of all planets, the Ascendant, and the 12 astrological houses at the moment you were born, using high-precision astronomical ephemeris (Swiss Ephemeris).

How is ERA different from other horoscopes?

ERA doesn't use your generic sun sign. It calculates your complete natal chart, current progressed chart, and planetary cycles to answer specific questions about your real situation — work, relationships, relocations, compatibility. Every answer is based on your exact sky, not generic predictions for millions of people.

Does ERA use artificial intelligence?

Yes. ERA combines precise astrological calculations with advanced artificial intelligence to interpret your natal and progressed chart. The AI is built on a unique interpretive methodology transmitted through real practice — delivering strategic interpretations, not generic responses.

What is a progressed chart?

A progressed chart shows how your natal chart has evolved over time. It reflects who you are today, not just who you were born as. ERA bases its interpretations primarily on your current progressed chart, making every answer relevant to your present moment.

What is astrocartography?

Astrocartography shows how your astrological chart changes depending on where in the world you live. ERA can calculate how your planets and houses would reorganize if you moved to another city or country, helping you make relocation decisions based on your chart.

Can I use ERA for free?

Yes. ERA has a free plan with 5 messages per month. The Pro plan costs $9/month (or $90/year with 2 months free) and includes unlimited messages and full access to all astrological interpretation features.

Does ERA work on Android?

Yes. ERA is available as a progressive web app (PWA) at eraastrology.ai and as a native Android application. It can also be installed directly from the browser on any device.

Sagittarius and Aquarius — Astrological Compatibility

Affinity

Sagittarius and Aquarius form a sextile between Jupiter and Uranus — the two planets most associated with freedom, expansion, and breaking convention. Sagittarius' Jupiter expands through direct experience, travel, and philosophy. Aquarius' Uranus expands through innovation, technology, and ideas that challenge the status quo. Together, they are the couple that accepts no limits.

The fire-air harmony is electrifying. Sagittarius brings enthusiasm, optimism, and direct action. Aquarius brings vision, originality, and unconventional thinking. Both need freedom and respect it mutually — something rare and valuable. The risk is that neither wants to land: they can live in ideas and plans without executing anything concrete.

The progressed chart defines whether this shared freedom becomes real construction. If Sagittarius' progressed Jupiter enters Capricorn, the enthusiasm gains structure. If Aquarius' progressed Uranus connects with water signs, emotional depth appears. ERA calculates those positions to show whether this sextile has the foundation to last.

Strengths

&check;Genuine mutual freedom — Jupiter and Uranus together don't tolerate cages
&check;Shared future vision — both want to change the world in their own way
&check;Constant intellectual stimulation — boredom is impossible in this pair

Challenges

×Both may avoid emotional intimacy by preferring the intellectual
×Lack of grounding — without earth signs in the dynamic, the practical is neglected
×Commitment may feel like restriction for two independent spirits
