Calendar

A month grid, keyboard-navigable per the WAI-ARIA Authoring Practices grid pattern.

Client component4 exportsSource

Import

import { Calendar, formatDate, parseISODate, toISODate } from '@the_viveksingh/vivek-ui'

Pick a date

A grid with real roving focus: arrows move a day, Page Up and Page Down move a month, Home and End reach the week bounds.

August 2026
SundayMondayTuesdayWednesdayThursdayFridaySaturday
<Calendar defaultValue={new Date(2026, 7, 21)} onValueChange={setDate} />

A range

mode="range" changes the value to { start, end }. The union means the single-date handler will not typecheck here.

<Calendar
  mode="range"
  defaultValue={{ start: new Date(2026, 7, 12), end: new Date(2026, 7, 19) }}
  onValueChange={setRange}
/>

Bounds and blocked dates

disabledDates takes a list or a predicate, so "no weekends" and "not these holidays" both fit without a second prop. The predicate form needs a Client Component around it - it has to run for months the server never rendered - while an array of Dates crosses the boundary fine.
