Four Pillars from your birth details
Saju is a traditional Korean system that represents the year, month, day and hour of birth as four pillars. Each pillar contains a heavenly stem and an earthly branch: eight characters in total. Interpretations look at the Day Master and the relationships between Wood, Fire, Earth, Metal and Water. This is a different calculation system from a Western sun sign. Your birth city and time zone also matter when calculating the chart.
How to get a free Saju reading
Enter a name or nickname, your birth date and your actual birth city. Select the correct solar or lunar calendar. If you do not know your birth time, leave it blank rather than guessing an hour. Seoul Saju offers a brief personal overview without requiring an account. You can review what a paid specialist or comprehensive report includes and its full price on the results page before choosing whether to purchase.
Reading Saju with ChatGPT or another AI
Check the birth inputs and calculated chart before judging the interpretation. Fluent or detailed writing does not by itself establish that the pillars were calculated correctly. Seoul Saju generates its AI interpretation from calculated chart data. Use the reading as a prompt for reflection alongside your own experience and practical information, especially for decisions about health, money or relationships. The free overview and public sample let you inspect the writing before buying a report.
