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.
PRIVACY AND OFFLINE USE
No account registration, ads, or tracking in the app. Calendar displays, widgets, local reminders, settings, and cached Premium access use data on your device. Apple handles payments and refunds. RevenueCat manages anonymous purchase validation, entitlements, restores, and purchase analytics. Product information, purchases, restores, and purchase-status updates may require a connection to Apple and RevenueCat.
Hibi Premium is an optional non-consumable in-app purchase, not a subscription. The price is shown in the App Store, and eligible purchases can be restored with the same Apple Account.
Sources and licenses are available in the app. Use calendar information for everyday reference.
