🀄 How it works: Your solar birth date is converted to the lunar calendar using real astronomical calendar data, and the day's traditional 60-cycle pillar is looked up. These feed into the traditional Tojeong-Bigyeol formula (Taese/Wolgeon/Iljin numbers) to compute your upper/middle/lower gwe, which is then interpreted through real I Ching Eight Trigrams symbolism — not the literal historical verse text, which we do not have a verified source for. This is traditional-interpretation entertainment content, not medical, legal, or financial advice.
