About
About Shadcn UI Big Calendar
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.

It is an open source template in the shadcn.io collection of 215.
Shadcn UI Big Calendar is made by List jonas, an independent developer; shadcn.io lists it but did not make it. List jonas has 1 template in the collection, and the author's page lists them.
The listing tags Shadcn UI Big Calendar with Next.js, React and Tailwind. Those are its categories, not a dependency list: the exact packages and versions are in the repository's package.json.
Yes. The Shadcn UI Big Calendar page embeds its live demo from shadcn-ui-big-calendar.vercel.app, and links to it so you can open the real deployment before you clone.
The Shadcn UI Big Calendar listing was last updated on October 8, 2025. That date is the listing's, not the repository's: check the repository's commits for recent activity.
Clone the repository (git clone https://github.com/list-jonas/shadcn-ui-big-calendar), then follow the README. The Shadcn UI Big Calendar page shows the usual steps and a terminal block with the commands to copy.
Install dependencies with npm install or pnpm install, then run npm run dev. The README in the Shadcn UI Big Calendar repository says which package manager and environment variables it needs.
No. Shadcn UI Big Calendar is cloned from its own GitHub repository, so shadcn.io isn't involved. Browsing the page and its live demo need no account either; Pro adds the premium templates, the blocks and the MCP server.
Shadcn UI Big Calendar is tagged Next.js, so it deploys wherever a Next.js app does, such as Vercel, a Node.js server or a container. Its README may add steps for its own services.
The Shadcn UI Big Calendar listing doesn't record a license. Check the LICENSE file in its repository (https://github.com/list-jonas/shadcn-ui-big-calendar), and ask the author if there isn't one.
That depends on Shadcn UI Big Calendar's license in its repository, which shadcn.io does not set. Read the LICENSE file before you use it in a client or paid project, and ask the author if it is unclear.

Yes. Components are free with a free account and the blocks are in Pro; both are copied into your project with the shadcn CLI. Check that Shadcn UI Big Calendar uses Tailwind CSS and the shadcn/ui setup (a components.json) before you add them, and pick the base library your project already uses.
