## What it is
CosmoCalendar is a fully customizable calendar view library for Android written in Java, supporting single, multiple, and range date selection modes. It offers extensive theming options including colors, icons, weekend days, connected/holiday days, and disabled days.

## Use cases
- add a date picker to an android app
- customizable calendar view for android
- select a date range in android ui
- show holidays on a calendar in android
- android calendar dialog with multiple date selection

## When to choose
- you need a native Android calendar widget with single, multiple, or range selection
- you want deep customization of calendar colors, icons, weekends, and disabled days
- you need to mark special days like holidays inside a calendar view

## When to avoid
- you are building for iOS or cross-platform frameworks rather than native Android
- you need a library with frequent updates and long-term active maintenance
- you need a full scheduling or event-management calendar rather than a date picker
