WHY SAJU MINGLE

Same birthday, different Saju. Why?

Saju writes down the moment you were born as eight characters. But many sites only look at the date when the seasons change, and use your clock time as it is. In reality, a few minutes in early February can change your zodiac year — and in Seoul the clock runs about 30 minutes ahead of the real sun.

Saju Mingle calculates every one of those differences.

Five things Saju Mingle does differently

01PRECISE

Down to the minute the seasons change

In Saju, your year and month don’t change on the 1st — they change at the exact moment a season turns. We calculate those moments with astronomy and checked 693 of them (2000–2028) against official Korean astronomy data. Every one is within a minute.

693 official times checked1,867 lunar months match
02TRUE SOLAR TIME

In Seoul, noon arrives around 12:30

Clocks follow time zones, not the sun. In Seoul the sun runs about 30 minutes behind the clock. We set your birth hour by where the sun really was at your birthplace — including that year’s time zone and daylight saving.

03EVIDENCE

Not just a verdict — the reasoning too

We don’t stop at “your energy is weak.” See which characters added how much strength, and why we picked the energy you need most — every step laid out in the open.

04PRIVATE

We never store your birthday

No account and no login. The birth details you enter never stay on our servers — your result lives only inside a signed link that you control.

05WORLDWIDE

Wherever you were born, read by that sky

Born in New York? We use New York’s longitude and the daylight-saving rule of that very year. Every country’s time-zone changes since 1900 are followed exactly as they happened.

Reading

The character that stands for you is Yang Wood (甲) — a tall tree growing straight toward the light. You carry the energy of beginnings: you start things, take the lead, and hold to principles you have decided on. Roles where you open a path for others suit you better than roles where you follow one. Your energy runs on the weaker side. You tend to stand firm until you are exhausted rather than bend, so choosing people and environments that support you is itself a source of strength; do not try to hold everything up alone.

Your five energies

  • Wood (木)10.6%
  • Fire (火)50.6%
  • Earth (土)10.1%
  • Metal (金)6.8%

Frequently asked questions

Can I get a reading without my birth time?

Yes. Without the hour we read the other six characters. You still see your personality and the big flow of your energies, and anything that needs the hour is marked on your result.

I only know my lunar birthday.

You can enter lunar dates, including leap months. We convert them with the lunar calendar of the country you were born in (1900–2050) before calculating.

Another site gave me a different chart. Which one is right?

Usually the rules differ: whether the real sun time is used, whether season changes are counted by date or by the exact minute, and which day 11 pm–midnight belongs to. Saju Mingle lists every rule it used right on your result.

I was born outside Korea.

Search for your birth city and select it. We calculate with that city’s longitude, time zone and the daylight-saving rule of that year. Enter the time exactly as the local clock showed it — don’t convert it.

Is it really free?

Where is my information stored?
