Short answer
Your Korean birthday type is one of ten saju types (the Tall Pine, the Climbing Flower, the Sun, the Candle, the Mountain, the Garden Field, the Sword, the Jewel, the Ocean and the Rain), and it is set by the day you were born, not the year.

Find my birthday type, freeHow your type is worked out
Korean saju counts days in a cycle of sixty that has run without a break for well over two thousand years. Each day carries one of ten heavenly stems, and the stem of your birth day is your birthday type. Because the stems repeat every ten days, someone born ten days after you shares your type. Someone born the day after you does not.
That is also why you cannot work it out from your star sign or your zodiac animal. It needs a proper day count, which the free check does in your browser. Your birthday is not sent anywhere.
The ten types at a glance
| Birthday type | Saju name | Element | In one line |
|---|---|---|---|
| The Tall Pine | Gap Wood 甲 | Yang Wood | Loyal, proud and steady. Protects first, talks later, and would rather fix your problem than say how they feel. |
| The Climbing Flower | Eul Wood 乙 | Yin Wood | Sweet, adaptable and quietly unstoppable. Bends to fit, remembers everything, and finds a way around every wall. |
| The Sun | Byeong Fire 丙 | Yang Fire | Warm, loud and generous. Loves big and fast, hates being ignored, and lights up every room including the group chat. |
| The Candle | Jeong Fire 丁 | Yin Fire | Quiet, deep and intensely loyal. Falls rarely and completely, reads meaning into everything, and remembers how you made them feel. |
| The Mountain | Mu Earth 戊 | Yang Earth | Calm, solid and protective. Slow to start, very hard to move, and shows love by quietly taking care of things. |
| The Garden Field | Gi Earth 己 | Yin Earth | Nurturing, practical and quietly brilliant. Notices everything, feeds everyone, and overthinks one text for forty minutes. |
| The Sword | Gyeong Metal 庚 | Yang Metal | Blunt, loyal and protective. Says the hard thing out loud, forgives slowly, and shows love by fixing your problems. |
| The Jewel | Sin Metal 辛 | Yin Metal | Elegant, sensitive and hard to forget. Wants to be chosen clearly and out loud, and goes politely cold when hurt. |
| The Ocean | Im Water 壬 | Yang Water | Free, curious and magnetic. Falls fast, dives deep, then needs air. Hates labels that feel like paperwork. |
| The Rain | Gye Water 癸 | Yin Water | Intuitive, gentle and quietly perceptive. Senses what is wrong before anyone says it, and analyses text tone like a contract. |

FAQ
Is my Korean birthday type the same as my zodiac animal?
No. The animal comes from your birth year and is shared by everyone born that year. Your birthday type comes from your birth day.
Can two people born in the same week have different types?
Yes. The type changes every day and repeats every ten days, so people born a few days apart usually have different types.
Does it matter what time I was born?
Only if you were born late in the evening. Many Korean readers treat 11 pm as the start of the next day, so births between 11 pm and midnight can land on the following day's type.
