## About

ioreum calculates Korean saju (四柱, Four Pillars of Destiny) charts the way a professional would: solar-term boundaries computed astronomically to the minute, true solar time from the birthplace, and the late-night hour convention. Ask for a chart, the 10-year luck pillars (daeun), which zodiac animal a January or February birth really belongs to, or a reference for any of the sixty day-pillar characters. Tools return calculated facts only and take nothing but the birth details you give them. Nothing here predicts events; treat it as reference and entertainment. Supported birth years: 1900 to 2050.

## How to use

1. **Add it in ChatGPT** Open ioreum Saju in ChatGPT's Plugin directory (button above), select + to add it and sign in if asked.

2. **Use it in a chat** Type @ in the composer and pick ioreum Saju, or start your message with its name. ChatGPT may also suggest it when it fits what you ask.

## Example prompts

- "Calculate my saju chart - born 1994-03-08 at 14:30 in Seoul, female."
- "I was born on February 2, 1990. Am I really a Snake or still a Horse?"
- "Explain the gapja (甲子) day pillar character."
