How do I add a calendar component in React?

Pick a component here and bind its selected value to your state. Month-grid variants report the chosen date on click, while event variants render a list of items you pass in. Copy the TSX and connect it to your form or data source.

What is the difference between a calendar and a date picker?

A calendar displays a month or schedule and can show events, while a date picker is a compact input for choosing one date or a range. For form fields, reach for a date picker; for viewing or booking time, use a calendar. Both categories exist on 21st.dev.

Can these calendars display and manage events?

Some can. Event calendar variants render blocks across days or time slots and often support selecting or moving them. Pass your events as an array with start and end times, and handle changes in your own state. Check each preview to see which interactions it supports.

Do these calendar components work in Next.js?

Yes. They are React and Tailwind-based and fit any Next.js project. Interactive calendars use hooks, so add use client to those files in the app router. Static month displays can render on the server.
