Yes. We leave out the two characters of the Hour Pillar and read the remaining six characters. The big picture of your personality, wealth, and career, as well as your 10-year luck cycles, still come through; only items that need the Hour Pillar, such as the spouse palace, are less accurate.
Enter your solar (Gregorian) birthday. Saju divides months by solar terms, so it doesn’t use lunar dates as they are. Jeombom calculates based on solar term data from the Korea Astronomy and Space Science Institute (KASI).
The free screens are summaries. In-depth reports explain everything — from the chart overview to strength balance (eokbu), Useful God, special stars, and the 12 life stages, to the flow over time — at length, in prose you can actually read .

For all three at once, the 3-Report Bundle is $24.99, and the easy-start “2027 Good Months & Careful Months” and “30-Day Fortune Calendar” (30 days from purchase) are $2.99 each.

We follow KASI’s solar term data and correct for true solar time. Korean Standard Time is based on 135°E, but the central longitude of the Korean Peninsula is about 127.5°E, so we subtract 30 minutes plus the equation of time, which varies by date (about 14–44 minutes in total, depending on the date), to convert to actual solar time before setting the Hour Pillar. We also account for 12 daylight saving time periods (1948–1951, 1955–1960, 1987–1988) and the period from Mar 21, 1954 to Aug 9, 1961, when Korean Standard Time was based on 127.5°E (UTC+8:30).

It’s the Heavenly Stem of the day you were born. Of the eight characters in your saju, it’s the one that represents “you”, and it’s the reference point for every interpretation. There are ten: Gap Wood, Eul Wood, Byeong Fire, Jeong Fire, Mu Earth, Gi Earth, Gyeong Metal, Sin Metal, Im Water, and Gye Water. See all 10 Day Masters explained
In your saju, it’s the energy you lack and need to fill in. When a 10-year luck cycle or yearly luck supports your Useful God, it’s seen as a time when the same effort brings better results. Jeombom determines the Useful God by looking at both strength balance (eokbu) and seasonal climate (johu).
No. Your zodiac sign looks only at the Earthly Branch of your birth year — a single character — so even people with the same sign have different flows if their full saju differs. To get close to reality, you need all eight characters from your date and time of birth, read together with your 10-year luck cycles and yearly luck.

Jeombom is a Korean saju service that builds its saju calendar from Korea Astronomy and Space Science Institute (KASI) solar term data and corrects your birth time to true solar time to calculate the eight characters of your saju.
| Item | Jeombom standard |
|---|---|
| Solar terms · saju calendar | Korea Astronomy and Space Science Institute (KASI) solar term data |
| Birth time | True solar time correction — subtracts the 30-minute difference between standard time (135°E) and the center of the Korean Peninsula (about 127.5°E), plus the equation of time, which varies by date |
| Daylight saving time | 12 periods in 1948–1951, 1955–1960, and 1987–1988 reflected |
| Former standard time | Period from Mar 21, 1954 to Aug 9, 1961 at 127.5°E reflected |
| Input | Solar date of birth (convert a lunar birthday to solar before entering) |
Because clock time and actual solar time can differ by around 30 minutes. If you were born during a daylight saving or former standard time period, your Hour Pillar may be off by one slot without correction. Detailed records are in Korean Standard Time records and Hour Pillar Check. For what to look for when choosing a free saju reading, see How to choose a free saju reading.
