A short guide for global readers

What Is Saju?

Saju, also called Korean Four Pillars or Myeongli, reads the year, month, day, and hour of birth as four pillars made from heavenly stems and earthly branches.

How does Today Gyeol calculate it?

Today Gyeol uses birth date, birth time, calendar type, gender basis, and birth country to calculate the natal chart, five-element balance, ten-god cues, solar time correction, decade luck, and annual flow in your browser.

Why ask for birth country?

True solar time can differ from clock time depending on location. In this MVP, Today Gyeol uses a country-level coordinate preset for approximation. City-level precision can be added later.

What is it not?

This is entertainment and self-reflection content. It is not medical, legal, investment, safety, or deterministic advice.

What is inside a shared link?

Shared URLs do not include birth date, birth time, gender basis, birth country, or nickname. They contain only a public report ID.
