Seasons
The Japanese seasonal calendar.
Sekki and Kō turn seasonal change into a way of reading light, weather, growth, and daily practice.

Sekki and Kō Calendars
The 24 Sekki divide the solar year into seasonal terms of about fifteen days. They came to Japan through the older East Asian lunisolar calendar tradition and helped people read the year by light, temperature, rainfall, wind, and plant growth.
Each Sekki is further divided into three Kō, creating 72 small seasons. These microseasons name delicate changes in nature: insects stirring, blossoms opening, grain ripening, mist rising, or frost beginning. The names turn observation into a calendar.
Why Sekki Matters
Sekki offered farmers, makers, cooks, poets, and households a practical rhythm for planting, harvest, festivals, preservation, and ceremony. It linked daily work to the movement of the sun.
Why Kō Matters
Kō asks for close attention. Instead of treating spring or summer as a single mood, it honors brief thresholds: the first song, the first flower, the first sign that a season is turning.
MichiRyu uses these calendars as a way to notice nature, arrange seasonal materials, and tell stories about how small changes shape a whole year.
