月と暦のカレンダー

This is a traditional Japanese calendar app.
It features three views: year, month, and day, allowing you to see the Japanese calendar, Japanese names for the months, the 24 solar terms, moon phases, and holidays at a glance.
Its simple and intuitive operation makes it easy to manage your schedule.

■Displayed Data
【Rokuyo (Six-Day Cycle)】Displays Taian, Tomobiki, Sensho, Senbu, Butsumetsu, and Shakko in the month and day views.
【Japanese Calendar and Alternative Names for Months】Displays the era name and Japanese names for the months in the header.

The data is pre-stored in the app, but it automatically checks and updates the latest data once a month.

■Year, Month, and Day Views
・Year View: Displays 12 months in a list. The current month is highlighted with a blue frame. Tapping a month moves you to the month view. Tapping the year in the header allows you to scroll through and select the year to display.

* Monthly View: A grid starting on Sunday, with the current day displayed in a blue frame. Sundays and holidays are in red, and Saturdays are in blue. 12 traditional Japanese colors adorn the header for each month. When viewing a month other than the current one, you can return to the current month using the "To This Month" button.

* Day View: The header consolidates the Rokuyo (six-day cycle), moon phase, twenty-four solar terms, and holiday names. You can see the calendar information for that day at a glance.

* Swipe horizontally to move forward or backward.

■ Schedule Management
* Tap a date to add an event immediately.
* Supports all-day events, time-specific events, and events spanning multiple days.
