Read about Twenty-Seven Mansions
About this reading: The 27 Lunar Mansions is an astrological system that originated in India, tracking the moon's roughly 27-day orbit of the earth and dividing the sky into 27 corresponding "mansions." It traveled through China to Japan, where it was systematized in the esoteric Buddhist text known as the Sukuyokyo, giving it the alternate name "Sukuyo astrology." Your nature, fortune, and compatibility are read from the idea of which lunar mansion the moon occupied on the day you were born.
In the traditional Sukuyokyo method, the birth date is converted to the old lunisolar calendar (fixed by the new moon and the twenty-four solar terms, in Japan Standard Time), and the mansions are counted in order, one per day, from a fixed "first-day mansion" for each lunar month (the Encampment Mansion for month 1, the Legs Mansion for month 2, the Stomach Mansion for month 3, and so on). This site uses the same traditional method, for dates from 1900 to 2100. A leap month is treated like the month before it. For people born on the 30th of a lunar month or in a leap month, the mansions can repeat or step back, and schools and sources differ in how they handle it.
Lore column: The Single Character "Mitsu" in the Heian Calendar: How the Sukuyo Sutra Brought the Days of the Week
A short read on the legends and strange tales around this reading, with this site's own view.
The Sukuyo Sutra did not carry only the divination of the twenty-seven lunar mansions. The seven-day week, sun, moon, fire, water, wood, metal, and earth, is also said to have reached Japan through this sutra, which the monk Kukai brought back from Tang China in the early ninth century. In the guchu-reki calendars made by Heian-period onmyoji, the days of the week were already written in alongside the sexagenary signs and notes on good and bad fortune.
Fujiwara no Michinaga's handwritten diary, the Mido Kanpaku-ki, also records days of the week, and its entry for a "Sunday" corresponding to March 12, 1004 has been confirmed as correct by calculation. Intriguingly, the calendars of the time marked Sunday with the character mitsu, said to derive from mir, a Sogdian word for the sun. The sukuyo-shi, specialists in this astrology, are said to have practiced horoscopes widely among the Fujiwara-era nobility, not only esoteric Buddhist rites.
As we see it here, that single character is the trace of a far-western name for the sun that reached the Japanese calendar after losing its meaning along the way. This is speculation, but to Heian nobles the character may have been a faintly secret mark, readable yet of unknown origin. Opening the almanac every morning and facing an unfamiliar sign that might sway one's fate: the awe that star divination inspired may have been born from exactly that sense of not knowing.
