The short answer
Choose react-native-calendars if you need…
- React Native developers who need a calendar or date picker screen
- Apps that need to mark dates with dots, periods, or custom styling
- Teams building scheduling or booking screens that block certain dates
- Projects that use Expo, since the README says it works there without ejecting
Choose Tamagui if you need…
- Teams building the same app for web and native with React
- Developers who want shared styling across React Native and react-native-web
- Projects that want an optional compiler to speed up styled components
- Developers who can set it up gradually inside an existing app

What each one is
react-native-calendars
React Native Calendars is a library that gives React Native app developers ready-made calendar components, including a single-month calendar, a scrollable calendar list, and an agenda view. Developers use it to show dates, mark days with dots or highlighted periods, and let users select dates. Per the README, it is pure JavaScript, so it needs no native module linking.
Tamagui
Tamagui is a set of open-source libraries for building user interfaces that run on both the web (React) and phones (React Native) from one shared codebase. It includes a styling library, an optional ready-made UI kit, and a compiler that rewrites styled components into faster output on each platform. Developers use it to share more code between web and native apps without giving up performance.

Strengths
react-native-calendars
- The README says it is pure JavaScript with no native code, so installation is simple
- Supports several marking styles and customization of style, content, and dates
- Has documentation and examples, and the README links to an official docs site
Tamagui
- Aims for shared code across web and native while keeping platform-specific performance, per the README
- Works gradually, so you can adopt it in parts of an existing project
- Released under the permissive MIT license
Not ideal for
react-native-calendars
- People who are not building a React Native app, since it is a component library for that framework
- Developers who need a native-looking calendar built directly on platform APIs, since the README describes it as a JavaScript implementation
- Projects that need the detailed API reference from the README alone, since the README points to an external documentation site for full details
Tamagui
- People who only need a plain website and no React (the project is built around React)
- Beginners without React or TypeScript experience, since the setup assumes both
- Projects that want a single, fixed design with no customization (the UI kit is optional and configurable)
Trade-offs
react-native-calendars
- The README is a basic guide and sends detailed usage to an external documentation site
- The README does not describe its performance or behavior on very old React Native versions
- The README mentions an example module that links to a private-looking repository path, so the sample source may be harder to reach
Tamagui
- The README's performance claims (such as a Lighthouse gain on its homepage) are the project's own measurements and were not independently verified here
- Compile-time and runtime behavior adds setup complexity compared with simple styling libraries
- The README is truncated, so details on setup and configuration are limited in this analysis
