Korean Saju in English: Your Four Pillars, Calculated Precisely
Saju (사주, "four pillars") is the Korean art of reading a birth chart built from the year, month, day and hour of birth — the same system known in Chinese as BaZi. Data Saju calculates charts with an almanac engine that follows the exact solar terms, and explains every result with the reasons behind it.
Find your Day Master and zodiac sign
Calculated in your browser; your date of birth is not sent anywhere. The Day Master uses your local date of birth. If you were born near midnight, or on the day of Lichun (around February 4), results for the neighbouring day or year may apply.

What is saju?
A saju chart has four pillars — year, month, day and hour — and each pillar has two characters: a heavenly stem on top and an earthly branch below. That makes eight characters (palja, 八字). Each character carries one of the five elements and a yin or yang quality. Reading a chart means looking at the balance of those elements, how the characters combine or clash, and how the ten-year and yearly cycles of luck meet the chart over a lifetime.
Why "data" saju?
Many online calculators take shortcuts: they ignore the exact moment the solar month changes, the longitude of the birthplace or historical daylight saving time. Our engine computes the solar terms astronomically, and every reading shows which characters it comes from. Your full reading, all ten personal reports, compatibility and the AI chat are all available in English.
