Swiss Ephemeris precision

Your sky,
decoded.

Natal, transit, and compatibility readings computed to sub-arcsecond accuracy — then interpreted with the depth of the tradition: houses, dignities, sect, and the stories your aspects are telling.

<1″Planetary positions accurate to under one arcsecond — Swiss Ephemeris, the standard professional astrologers trust.
2House systems computed for every chart: Placidus and whole sign.
45Planet-pair aspect dynamics, individually written — a Venus–Mars square never reads like a Moon–Saturn one.
0Stock interpretations. Dignity, sect, retrograde, and house placement shape every line.

Astrology that lives where you already think out loud.

CosmicPass runs inside ChatGPT — ask in plain language, get a computed chart back in the conversation.

Share your moment

Birth date, time, and place. We resolve the timezone, ΔT, and coordinates — the parts most apps fudge.

We compute the sky

Swiss Ephemeris places every body to sub-arcsecond precision; houses, aspects, dignities, and nodes follow.

Read your story

A narrative written from your actual placements — with the rendered wheel to keep, share, or frame.

“Your Saturn sits in Capricorn, in the sixth house of work and routine — at home in its own sign, steady and self-possessed. And because it moves retrograde, the discipline is rehearsed in private long before anyone gets to see it.”
