The Four Pillars
Your birth year, month, day and hour form four pillars. Each pillar has two characters, giving the eight characters of a Saju birth chart.

YOUR OWN TEXTURE
THE FIVE ELEMENTS WITHIN
Your elemental balance
The main elements of each stem and branch have equal weight. Percentages total 100%, rounded to one decimal place. If the birth time is unknown, only the six characters of the first three pillars are counted.
What do the Four Pillars mean?
The upper character of each pillar is a Heavenly Stem; the lower character is an Earthly Branch. The upper character of the day pillar, the Day Master, represents you at the center of the chart.
Think of the year pillar as roots, the month as the growing season, the day as your leaves and flowers, and the hour as fruit that develops over time.

Calculation method and reading notes
Enter a birth date from 1901 through today using the Gregorian or Korean lunar calendar. Select a country or territory, then a listed city or administrative area. South Korea uses the existing regional coordinates; overseas locations use GeoNames representative longitudes and IANA time zones. Street addresses and every small settlement are not supported. Korean lunar dates are converted to Gregorian; choose the leap-month option when applicable. Enter the local clock time recorded at birth. Historical standard time and daylight saving follow the birthplace’s IANA time-zone history. Local mean solar time adds (longitude × 4 − historical UTC offset × 60) minutes to the recorded time, keeping the correction within ±12 hours at the international date line. The equation of time is not applied; corrections are rounded to minutes. Day and hour pillars use the corrected local date and time, with the day changing at midnight (sect 2). Year and month pillars compare solar terms at the actual birth instant expressed in China Standard Time. If the time is unknown, local noon at the birthplace is used without solar-time correction or the hour pillar. Nonexistent local times during clock changes are rejected; for repeated times, the earlier occurrence is used and noted. Historical boundary changes, time-zone data and solar-term or time boundaries may cause differences from other calendars. Interpretations are for personal reflection.
