What you need
Your birth date is enough to calculate three pillars. Add the birth time when you know it to complete the hour pillar. The form also lets you choose solar or lunar calendar input.
What the free chart does not claim
A missing or abundant element is not automatically good or bad. The season and relationships across the full chart change how each element works. The free table gives you the facts; a reading adds context.
Frequently asked questions
What does a Saju chart show?+
It shows four pillars, eight stem-and-branch characters, your Day Master, the distribution of the Five Elements and your major ten-year cycles.
Is Saju the same as a Western birth chart?+
No. Both begin with birth information, but Saju uses the stem-and-branch calendar and Four Pillars rather than planets and zodiac houses.
