Western astrology gives you a sun sign. Korean Saju (사주, the Four Pillars of Destiny) goes deeper — it reads the exact day you were born to find your Day Master, the core "operating system" you run on. There are 10 Day Master types. Here is the quick map.
What is a Day Master?
Your Day Master is the element-and-polarity of the day you were born — the anchor of your whole chart. Think of it less like a horoscope and more like your default settings: how you process the world, where your energy naturally goes, and what you have to actively manage.
It is not a prediction. It is a pattern — 1,000 years of behavioral data, sorted.
The 10 types at a glance
Each type has a signature strength and a matching blind spot. The Pioneer starts everything; the Refiner perfects it. The Radiator fills the room; the Anchor steadies it. None is "better" — they just run different software.

Which one are you?
You cannot pick your Day Master — it was set the day you were born. A free Saju reading finds it in about 30 seconds, no login required, then shows your full element breakdown and your strongest matches.
