九星気学 Kyusei Kigaku — Japanese nine-star astrology. A quiet map, written personally in Japan. Not a prediction; a way of looking.
Find your starEnter your date of birth. The old calendar begins the year at 立春 Risshun — February 4th — so January and early-February births belong to the year before. Most quick lookups miss this; the calculator does not.
And if you keep time with the sky rather than the stars, the 2027 moon calendar is ready as well.
Each year belongs to one of nine. Touch a star to meet its temperament — or use the calculator above to find yours by birth date.
九星気学 Kyusei Kigaku — nine-star Ki-study — is a Japanese practice of reading time and temperament. Each year carries one of nine stars; the star of your birth year is called your 本命星 Honmei-sei, your year star. Each star holds an element — water, wood, earth, metal, or fire — and a direction, and a way of moving through the world.
In Japan the practice is often used for timing and direction. Here we read it for temperament and season, and we do not promise outcomes. It offers a vocabulary for what is already true of you — the pace you keep, the strength you lean on, the season you are in — and invites you to work with it rather than against it.
The system counts its years from 立春 Risshun — the old beginning of spring, February 4th. A person born in January belongs to the star of the previous year. This small detail changes roughly one reading in nine, which is why the calculator above handles it for you.
In 九星気学 Kyusei Kigaku, 2027 carries 九紫火星 Kyushi Kasei, the Ninth Purple Fire Star. The almanac holds a chapter for every one of the nine stars — the star's temperament, the fire year's theme, reflections for its four seasons, and three small practices.

Visit the shopOne practitioner in Japan. I was born and raised here, grew up around the old calendar's habits, and first learned 九星気学 Kyusei Kigaku from my grandparents, by word of mouth.
Every reading is written personally, for one person at a time, and I read the messages that come in myself. English is my second language, so the sentences stay plain. If that pace suits you, you are in the right place.
How a reading is made: your star is calculated twice, from your date of birth, with the Risshun boundary applied. The reading is drafted around that star and the year's star, then read, corrected and signed by one person before it is sent. It uses the year, month and day of birth — nothing else — and it does not give lucky directions, numbers or predictions.

Your name and date of birth. Kyusei Kigaku reads the year, month and day — the hour of birth is not used, so there is nothing more to send.
No. A reading describes tendencies and seasons — what a year may invite, not what it will bring. What you do inside that weather remains yours.
One practitioner, in Japan, one person at a time. Each reading is drafted, checked and revised before it is sent; that is why delivery is measured in days and not in seconds.

The old calendar turns at 立春 Risshun — the beginning of spring — and why that boundary changes roughly one reading in nine.
