テキストカレンダーウィジェット is a simple and efficient calendar widget for Android devices. It offers three different sizes - 1x1, 2x1, and 2x2 - to suit your preferences. Unlike other calendar widgets, it does not run in the background, resulting in minimal battery consumption. However, this also means that automatic date updates may fail at times, requiring manual updates.

By tapping on the widget, you can access the settings menu and customize various aspects of the widget, including the displayed month (current, next, or previous), the displayed dates (only the selected month or including dates from adjacent months), the first day of the week (Sunday to Saturday), the style for the current day (change text color, change background color, or no emphasis), the background style (rounded corners, rectangular, or none), the font size adjustmentto +4.0), and the highlighting of holidays.

Please note that this widget is not compatible with Japanese public holidays after April 2019, and the developer has not provided an estimated completion date for the ongoing improvements.
