Western astrology + Korean Saju

Two skies,
one you.

Æther reads your birth chart through two traditions at once — your Western natal chart and your Korean Saju (Four Pillars) — for a fuller picture of who you are, and where you're headed.

Why two skies

One chart can only say so much.

Western astrology and Korean Saju watch the same life from two different windows. Read together, they catch what either one alone would miss.

The West · Natal chart

The inner "why"

Your Sun, Moon, and Rising — the planets and houses that map temperament, motivation, and the way you move through the world.

Sample · Synthesis reading

"You read as careful. You're built to move."

Your Virgo Sun keeps the surface tidy and precise — but your Day Master is Yang Water, which doesn't ask permission. The reading walks through where those two pull together, and where they pull apart: in love, in work, in money, and in the shape of the year ahead.

— The full reading continues across personality, relationships, career, wealth, and this year's fortune.

Questions

Before you start.

Is this fortune-telling?

No. Æther is a tool for self-reflection. It maps the patterns two traditions see in your chart — it doesn't predict fixed events.

What do I need to start?

Your date, time, and place of birth. If you don't know your exact birth time, you can still get most of the reading.

Do I need to know astrology or Saju?

Not at all. Every term — Day Master, Five Elements, houses — is explained as it appears.

Is my birth data private?

Yes. Your details are used to compute your reading and, only if you sign in, to save it to your account. See our privacy policy.
