A lightweight, customizable Android calendar widget with infinite scroll, multiple selection modes, and visual indicators.
CrunchyCalendar is an open-source Android library that provides a customizable calendar widget with Material Design aesthetics. It solves the problem of implementing complex calendar functionalities—like infinite scrolling, range selection, and visual date indicators—without building from scratch. Developers can seamlessly integrate it into their apps to handle date picking and event display.
Android developers building apps that require calendar features, such as booking systems, event planners, travel apps, or any application needing date selection and visualization.
Developers choose CrunchyCalendar for its combination of a lightweight codebase, out-of-the-box features like infinite scroll and multiple selection modes, and extensive styling options. It saves development time while offering a polished, maintainable component that adheres to modern Android practices.

Allows smooth vertical scrolling in both directions with configurable date boundaries, ideal for browsing long time periods without pagination, as highlighted in the README's key features.
Supports single, multiple, and range selection with custom filtration logic, enabling complex date interaction for booking or scheduling apps, demonstrated in the selection examples.
Style via XML attributes or programmatically, including colors, indicators, and custom item decorations, making it highly adaptable to diverse app designs, as shown in the styling sections.
Saves and restores selection state on configuration changes, reducing boilerplate code and improving user experience, explicitly noted in the README's state management section.
Only provides a month view with vertical scrolling; lacks built-in support for week, day, or agenda views, which are common in scheduling applications and not mentioned in features.
Implementing features like custom indicators or additional text requires creating interfaces and managing data lists, which can be cumbersome for simple use cases, as seen in the indicator and text setup examples.
As a subclass of View, it may not integrate seamlessly with modern Android UI frameworks like Jetpack Compose, limiting its use in contemporary projects, and the README doesn't address Compose compatibility.
