A JAPANESE CALENDAR, WHEREVER YOU ARE Rokuyo is a traditional six-day cycle that includes Taian and Butsumetsu. Day markers such as Ichiryumanbaibi and Tenshanichi are cultural calendar traditions, provided for reference rather than as predictions or guarantees of good fortune.

Calendar dates and calculations use Japan Standard Time (JST). Weeks begin on Sunday. Solar-term names describe Japan’s seasonal cycle; they do not adapt to your local climate or hemisphere. Lunar dates, rokuyo, and day markers may differ between calendar methods. Hibi is not a personal appointment calendar.
