Explore your qualities and connections through the calendar's 27 mansions

What is Sukuyo astrology?

The Moon takes about 27 days to circle among the stars. In ancient India, its path was divided into 27 sections, and the section occupied by the Moon was used to read character and favorable or unfavorable conditions. These ideas were compiled in China into the Sukuyo Sutra and transmitted to Japan by Kobo Daishi Kukai during the Heian period.

This reading counts calendar months and days across 27 mansions without assigning the Ox mansion separately. It is distinguished from measuring the Moon's actual position each time; the selected new-moon calendar's dates and counting method are shown as the basis of the result.

The three groups of nine: a compatibility method

A distinctive feature of Sukuyo astrology is the three-groups-of-nine method, which reads compatibility from the relative positions of two mansions. Relationships fall into the following six categories.

• Check your shared perspective through words（Mei pairing）：Shared tastes and interests may make it easy to start talking again, even after a long time apart. Alongside what you have in common, asking about a view the other person has recently changed may open a new conversation.
• Make mutual support concrete（Ei–Shin pairing）：This relationship can be read as checking in with each other and offering small forms of help. Before doing something for the other person, you can ask whether they want someone to listen or a hand with a task.
• Leave room within the enjoyment of conversation（Yu–Sui pairing）：Talking about shared interests may become a way to reconnect. Even if your lives are moving in different directions, you can still take turns introducing what you enjoy now.
• Try a different approach on a small scale（An–Kai pairing）：This relationship can be read as revisiting your own choices through the other person's different approach. Rather than rushing to agree, you can check how far you are comfortable working together.
• Move forward with shared conditions and a stopping point（Ki–Sei pairing）：This relationship can be read as learning about interests you do not share and giving them a short try. Whether an invitation suits you can be decided from how one actual experience feels.
• Connect experience with new hopes（Go–Tai pairing）：This relationship can be read as connecting time spent sharing experiences with time spent introducing new interests. Even with someone you have known for years, you can ask about wishes that have recently changed.
