Shadcn Calendar: Plan, Pick Dates, and Schedule with Ease#

The Shadcn Calendar is a flexible, accessible date UI for selecting single dates, ranges, and navigating months/years. Ideal for booking flows, dashboards, and forms, it provides a clean API and full styling control with Tailwind—perfect for any React Calendar implementation.

What is Shadcn Calendar?#

The Shadcn Calendar renders a navigable grid of days with controls for month and year switching. It supports single-date selection, multi-date selection, and date-range picking.

The core exposes composable parts—navigation, day cells, week headers—so you can style or swap behaviors freely. Basic styled by default, it's designed to pair perfectly with Tailwind CSS while maintaining keyboard and screen-reader accessibility.

Why Use Shadcn Calendar?#

• Accessible by Design: Proper roles, labels, and keyboard support ensure inclusive interactions.
• Single/Range/Multi Select: Covers common scenarios from birthdays to hotel check-ins and reporting periods.
• Full Customization: Tailor everything—headers, day cells, disabled states, and hover ranges—without fighting a fixed theme.
• Lightweight & Performant: Minimal overhead and predictable rendering for snappy React Calendar UIs.
• i18n & Localization Friendly: Works well with date libraries to localize month names, first-day-of-week, and formats.

Features#

• Modes: single, multiple, and range selection with controlled or uncontrolled state.
• Disabled/Unavailable Days: Block past/future dates, weekends, or custom rules (e.g., company holidays).
• Keyboard Navigation: Arrow keys to move days, PageUp/PageDown for months, Home/End for week boundaries, Enter/Space to select.
• Month/Year Navigation: Quick jumps with dropdowns or previous/next controls; optional multi-month view.
• Hover Preview for Ranges: Show tentative range as users move the cursor for clearer selection.
• Custom Day Rendering: Inject badges, prices, events, or status dots into day cells.
• Timezone & Min/Max Support: Respect min/max constraints and adapt with your date util of choice.

Production Tips#

• Use a Date Utility: Pair with libraries like date-fns or Day.js for parsing, formatting, and locale support; keep conversions at the boundary of your component.
• Block Invalid Periods: Disable past dates for bookings, or blackout maintenance windows; this reduces user error and validation code.
• Mobile Considerations: Provide larger hit targets and consider a month picker or native input fallback for very small screens.
• Range UX: Show start/end highlights, hovered range preview, and clear reset affordances (e.g., a "Clear" Shadcn Button).
• Accessibility: Ensure focus is visible on day cells, announce current month/year, and use ARIA attributes for selected/disabled states.
• Server Boundaries: When used in forms, store ISO strings (UTC) and convert on display to avoid timezone surprises.

Integration With Other Components#

The Shadcn Calendar pairs naturally with Shadcn Popover to create compact date pickers that open on focus or click, keeping forms uncluttered.

Combine it with Shadcn Input for a formatted date field that synchronizes with user selections in your React Calendar.

In scheduling dashboards, embed the calendar inside a Shadcn Card and use Shadcn Badge or small dots on day cells to indicate events or availability.

For booking flows, use Shadcn Button for "Apply" and "Clear", and Shadcn Tooltip to show per-day notes like pricing or blackout reasons.
