Birth time

Saju is Korea's birth-chart system: four pillars from the day and hour you were born. We read your pillars next to theirs, add your sun and moon, and give you one honest number.

How it works

  1. 1Enter your birth date. Hour is optional.
  2. 2Pick a group.
  3. 3Get your match: score, two lines on the chemistry, three facts, and a card to post.

What you get

  • Your best match in the group
  • A 0–100 match energy with the reasons
  • A story-size card in the group's color
  • Your full saju × Western report ($4.99, optional)
Example share card: a colour band on top, the group and member name set in a serif, a large match score, and two lines about the chemistry. Type only, no photos.

Questions

Is this official?

No. Fan-made, not affiliated with any artist or agency. For entertainment only.

Do you store my birthday?

No. It is used for the calculation and dropped. See the policy for what is kept.

What if I don't know my birth hour?

We use three pillars instead of four, and the result says so.

Is this real astrology?

It is real saju and Western math, read for fun, not for decisions.
