DateTimeInput

Combined date and time field: month/day/year plus hour/minute (and optional seconds / day-period) segments, with a popover calendar for the date portion. Defaults to granularity="minute". Values typically use CalendarDateTime from @internationalized/date.

Examples

Default

Pass a label and a CalendarDateTime defaultValue (or control via value / onChange).

Appointment

8122026230PM

import { CalendarDateTime } from '@internationalized/date';
import { DateTimeInput } from '@var-ui/react';

<DateTimeInput label="Appointment" defaultValue={new CalendarDateTime(2026, 8, 12, 14, 30)} />

Granularity

Set granularity to control the smallest editable time unit. "second" adds a seconds segment; "day" hides time segments entirely.

Appointment

812202623000PM

Includes a seconds segment

import { CalendarDateTime } from '@internationalized/date';
import { DateTimeInput } from '@var-ui/react';

<DateTimeInput
  label="Appointment"
  defaultValue={new CalendarDateTime(2026, 8, 12, 14, 30, 0)}
  granularity="second"
  description="Includes a seconds segment"
/>

Props

Accessibility

Built on React Aria DatePicker with time granularity. Date and time segments are individually focusable spinbuttons; the calendar trigger opens a dialog for picking the day (time stays in the text field). Keep label visible, and use description / errorMessage for helper and validation copy.

Props

Prop	Type	Default	Description
`className`	`(ClassNameOrFunction<DatePickerRenderProps> & string) \| undefined`	`'react-aria-DatePicker'`	The CSS [className](https://developer.mozilla.org/en-US/docs/Web/API/Element/className) for the element. A function may be provided to compute the class based on component state.
`description`	`string \| undefined`	—	Helper text shown below the control when there is no error.
`errorMessage`	`string \| undefined`	—	Validation message; when set, the field is shown in an error state.
`granularity`	`"day" \| "hour" \| "minute" \| "second" \| undefined`	`'minute'`	Smallest unit of time rendered as an editable segment. The popover calendar always operates at day granularity — time segments are edited via the text field, not the calendar.
`label`	`string \| undefined`	—	Field label rendered above the segmented group.

Requirements: - You must render the expected element type (e.g. if `<button>` is expected, you cannot render an `<a>`). - Only a single root DOM element can be rendered (no fragments). - You must pass through props and ref to the underlying DOM element, merging with your own prop as appropriate.

`validate`	`((value: MappedDateValue<T>) => true \| ValidationError \| null \| undefined) \| undefined`	—	A function that returns an error message if a given value is invalid. Validation errors are displayed to the user when the form is submitted if `validationBehavior="native"`. For realtime validation, use the `isInvalid` prop instead.
`validationBehavior`	`"native" \| "aria" \| undefined`	`'native'`	Whether to use native HTML form validation to prevent form submission when the value is missing or invalid, or mark the field as required or invalid via ARIA.
`value`	`T \| null \| undefined`	—	The current value (controlled).
