About This Template

The shadcn/ui Big Calendar is a beautifully styled integration of React Big Calendar with shadcn/ui's design system, providing seamless light and dark theme support through pure CSS variable-based theming without JavaScript manipulation. Built with Next.js, React, Tailwind CSS, and shadcn/ui components, this reusable calendar component automatically adjusts its appearance based on the selected theme using shadcn's CSS variables, creating smooth theme transitions and consistent visual experiences across your application. The implementation features automatic theme switching that respects user preferences and system settings, pure CSS-based theming eliminating JavaScript overhead for theme management, Next.js compatibility with server-side rendering support, multiple calendar views including month, week, day, and agenda layouts, full React Big Calendar functionality for event scheduling and management, responsive design adapting to mobile and desktop screen sizes, and a dedicated CSS stylesheet that leverages shadcn's color tokens for unified styling. Unlike standard React Big Calendar implementations that require manual theme configuration or complex JavaScript solutions, this integration uses CSS variables to ensure calendar colors, backgrounds, borders, and text automatically match your shadcn/ui theme, whether users prefer light mode during the day or dark mode at night. The component is perfect for building appointment scheduling applications for services, healthcare, or consulting, team calendar interfaces for project management and collaboration, event management platforms for conferences or community events, resource booking systems for meeting rooms or equipment, and any application requiring a full-featured calendar with professional, theme-aware styling. This project demonstrates how to integrate third-party React components with shadcn/ui's theming system, implement CSS variable-based theming for complex UI components, create reusable calendar solutions for Next.js applications, and maintain visual consistency across light and dark modes.
