What is saju?
In Korea, millions of people check their saju (사주) before a new year, a new job or a wedding. Saju means "four pillars": the year, month, day and hour of your birth. Each pillar is written with two characters, so the full chart is called saju palja (사주팔자), "four pillars, eight characters". The same system is known in Chinese as BaZi and in English as the Four Pillars of Destiny.
Unlike Western sun-sign astrology, saju is built from the solar calendar and the five elements: Wood, Fire, Earth, Metal and Water. The character of your birth day, your Day Master, represents you. The other seven characters show what supports you, what challenges you and how your energy shifts through 10-year luck cycles.

Frequently asked questions
What is a saju reading?
Saju (사주, "four pillars") is the Korean name for the Four Pillars of Destiny, known in Chinese as BaZi (八字, "eight characters"). Your birth year, month, day and hour are each converted into a pair of characters: a heavenly stem and an earthly branch. Those eight characters, and the balance of the five elements they contain, describe your temperament, strengths and the timing of life cycles.
Is Sajuwise free?
Yes. Your Four Pillars chart, Day Master profile, five-element balance, personality summary, lucky elements, yearly outlook and current 10-year luck cycle are free. Sajuwise Pro ($4.99/month, $29.99/year, or $9.99 one-time for one full reading) adds the deep career, love, wealth and health sections, a 12-month guide and daily fortune details.
How accurate is the calculation?
Sajuwise does a real astronomical calculation. Year and month pillars change at the exact solar terms (for example Lichun, the start of spring, around February 4), computed to the minute. The day pillar uses the Julian day number, and you can optionally correct the hour pillar to true local solar time based on your birth place's longitude.
What if I do not know my birth time?
Tick "I don't know my birth time". We calculate the three pillars we can know for sure (year, month, day). The Day Master, which is the heart of the reading, comes from the day pillar, so the core reading still works.
Is my birth data stored on a server?
No. All calculations happen on your device and your profile is kept in your browser's local storage. Compatibility invite links carry the birth details inside the link itself, so share them only with people you trust.
Is saju scientifically proven?
No. Saju is a traditional East Asian system for reflection, not a science, and it cannot predict events. Sajuwise is for entertainment and self-reflection; please do not use it to make medical, financial or legal decisions.
