Saju

Your free Saju chart,
from your exact birth time.

What this is

A Korean birth chart built from the year, month, day and hour you were born.

Saju is Korea’s birth chart. A star sign uses one thing about your birth, the date. Saju uses four: the year, the month, the day and the hour. Each becomes a pair of symbols, and those four pairs are the four pillars.

Those eight symbols carry a mix of five elements: wood, fire, earth, metal and water. The balance matters more than the list. What you have too much of, and what is missing entirely, is the part that describes your actual life.

Koreans use this the way the West uses personality tests. It’s about a thousand years old and considerably more specific.

Don’t know your birth time? That’s fine. Tick the box and we’ll read three pillars instead of four.

Birth date

Time of birth

AM PM

I don’t know my birth time Midnight is 12 AM. Noon is 12 PM. Get it as close as you can. Saju splits the day into two-hour blocks, so a few minutes only matters if you were born near the edge of one. We adjust for real sun time at your birthplace, so those edges usually aren’t where the clock says they are.

Place of birth Where you were born changes the chart. In Atlanta, for example, the sun runs 38 minutes behind the clock in winter and 98 minutes behind in summer.

No account and no card. Your chart is ready in seconds.

Why this one is different

Real sun time

Most free calculators use the time on the clock as it is. We work out where the sun actually was at your birthplace, and apply the daylight saving rules that were in force that year.

Correct year boundary

In Saju the year doesn’t start on January 1. It starts at the traditional beginning of spring, around February 4, at an exact moment. If you were born in late January or early February, most tools get your birth year wrong. This one doesn’t.

Explained, not just calculated

Each traditional term comes with a plain-English meaning, and the reading talks about your work, money and relationships rather than leaving you with a table of symbols.
