Korean Saju you can finally read
In Korea, people look up their Saju before a new year, a new job or a new relationship. Sajulume turns your birth date and time into the eight characters and explains each one in plain words: how Koreans read it, which element it is and what it stands for.
Sajulume has no lunar date input, no compatibility score and no built-in AI reading. It is a chart and an explanation of each character.

FAQ
- What is Saju?
- Saju (사주, four pillars) is the Korean tradition of reading a person's birth year, month, day and hour as eight characters. It uses the same system as Chinese BaZi.
- Do I need to know my birth time?
- No. Without a birth time the app shows the year, month and day pillars, six characters in total. Your Day Master does not depend on the hour unless you were born around 23:00.
- Why is my year pillar different from my zodiac year?
- In Saju the year changes at Ipchun, the start of spring around February 4, not on January 1 or Lunar New Year. Someone born in January belongs to the previous year's pillar.
- What is the 30-minute correction for Korea?
- Korean Standard Time runs about 30 minutes ahead of the sun over Korea, so Korean almanacs subtract 30 minutes from the clock time. You can turn this on or off for each chart.
- Does it work offline?
- Yes. Every chart is calculated on your phone. The internet is only used to show ads.
- Is there a subscription or sign-up?
- No. There is no account and no subscription. The app is supported by ads.
- Does it have AI readings?
- Not built in. The app can copy a ready-made prompt with your chart so you can ask any AI chat yourself.
- Is Saju accurate?
- Saju is a cultural tradition, and Sajulume is for interest and entertainment. It describes tendencies and is not professional advice.
