Date Fields

Dependency Disclaimer

In order to deliver true i18n for international audiences, Formwerk’s date field composable depends on @internationalized/date to provide these functionalities.

If you do not use the Calendar, Date Field or Time Field composables, the dependency will not be included in your bundle as it is fully tree-shakable.

Formwerk fully intends on migrating to the Temporal API in the future once they receive full or partial baseline support.

Date fields are a type of input field that allows users to enter a date. They are a common feature in many web applications, and Formwerk provides a useDateTimeField composable that can be used to create date fields in your application.

Features

• Labeling, Descriptions, and error messages are automatically linked to the date field elements.
• Support for multiple calendars (e.g: islamic-umalqura, japanese, etc).
• Supports minimum and maximum date boundaries.
• Validation support with native HTML constraints or Standard Schemas.
• Auto directionality based on the locale.
• Focus management and auto navigation for date segments.
• Support for v-model binding.
• Comprehensive keyboard shortcuts support.

Keyboard Features

Key	Description
↓ArrowDown	Decrements selected segment by 1.
↑ArrowUp	Increments selected segment by 1.
←ArrowLeft	Moves the focus to the previous segment.
→ArrowRight	Moves the focus to the next segment.
⌦Delete	Clears the current segment.
⌫Backspace	Clears the current segment.
⇥Tab	Moves the focus to the next segment or next element in the tab index order if it is the last segment.

Building a Date Field Component

Just like the native HTML date field, the date field in Formwork is compromised of date segments, each segment represents a part of the date/time value (e.g: day, month, year, hour, minute, etc).

The segments are generated for you automatically based on the formatOptions you pass to the useDateTimeField composable. You will need to bind the prop objects returned by the composable to the corresponding DOM elements in the anatomy.

If you do not pass the formatOptions prop, the date field will use the default format options for the locale of your app.

The DateTimeSegment component is used to render each segment of the date field. We provide one for convenience that you can use. You can also build your own with useDateTimeSegment composable.

<script setup lang="ts">
import { useDateTimeSegment, type DateTimeSegmentProps } from '@formwerk/core';

const props = defineProps<DateTimeSegmentProps>();

const { segmentProps, label } = useDateTimeSegment(props);
</script>

<template>
  <div v-bind="segmentProps">
    {{ label }}
  </div>
</template>

Validation

HTML Constraints

You can use the following properties to validate the date field with native HTML constraint validation:

Name	Type	Description
min	Date	The minimum date that can be entered.
max	Date	The maximum date that can be entered.
required	boolean	Whether the date field is required.

<script setup lang="ts">
import DateField from './DateField.vue';
</script>

<template>
  <DateField
    label="HTML Constraints"
    required
    :min="new Date('2025-01-01')"
    :max="new Date('2025-12-31')"
  />
</template>

Expand

Standard Schema

useDateTimeField supports Standard Schema validation through the schema prop. This includes multiple providers like Zod, Valibot, Arktype, and more.

Note

Depending on the schema validation provider you are using, the API might slightly differ. Check the supported validation providers for more information. In this example, we are using the zod schema validation provider.

In this example, we are validating that the date field is between January 1st, 2025 and December 31st, 2025.

<script setup lang="ts">
import { z } from 'zod';
import DateField from './DateField.vue';

const schema = z.date().min(new Date('2025-01-01')).max(new Date('2025-12-31'));
</script>

<template>
  <DateField label="Standard Schema" :schema="schema" />
</template>

Mixed Validation

All date fields created with Formwerk support mixed validation, which means you can use both HTML constraints and Standard Schema validation to validate the field, and they work seamlessly together.

Note that HTML constraints are validated first, so any errors from the HTML constraints will be displayed first. Then, once all HTML constraints are satisfied, the Standard Schema is validated.

<script setup lang="ts">
import { z } from 'zod';
import DateField from './DateField.vue';

const schema = z.date().min(new Date('2025-01-01')).max(new Date('2025-12-31'));
</script>

<template>
  <DateField label="Mixed Validation" :schema="schema" required />
</template>

Usage

Disabled

Use the disabled prop to disable the date field. Disabled date fields are not validated and are not submitted.

If you need to prevent the user from interacting with the field while still allowing it to submit, consider using readonly instead.

<script setup lang="ts">
import DateField from './DateField.vue';
</script>

<template>
  <DateField label="Disabled" :value="new Date('2025-02-11')" disabled />
</template>

Readonly

Use the readonly prop to make the date field read-only. Read-only date fields are still validated and submitted.

<script setup lang="ts">
import DateField from './DateField.vue';
</script>

<template>
  <DateField label="Readonly" :value="new Date('2025-02-11')" readonly />
</template>

Min and Max

You can pass min and max props to set the minimum and maximum dates that can be entered, not only they are used for validation but they affect the date segments that are available for selection and interaction.

<script setup lang="ts">
import DateField from './DateField.vue';
</script>

<template>
  <DateField
    label="Same Year and Month"
    :min="new Date('2025-02-01')"
    :max="new Date('2025-02-15')"
  />

  <DateField
    label="Same Year"
    :min="new Date('2025-01-01')"
    :max="new Date('2025-12-31')"
  />

  <DateField
    label="Different Year"
    :min="new Date('2024-01-01')"
    :max="new Date('2025-12-31')"
  />
</template>

Expand

Notice in the previous examples, some parts of the date field are disabled.

This is because when providing both a min and a max, Formwerk checks the possibilities of the date segments, and if a segment has only one possible value then it automatically sets it and disables it. Just like the native input[type="date"] element.

Format Options

You can pass any Intl.DateTimeFormatOptions to the formatOptions prop to customize the date field’s display format.

<script setup lang="ts">
import DateField from './DateField.vue';
</script>

<template>
  <DateField
    label="Format Options"
    :formatOptions="{
      year: 'numeric',
      month: 'short',
      day: 'numeric',
      hour: '2-digit',
      minute: '2-digit',
      hour12: true,
    }"
  />
</template>

Locale and Calendar Support

The calendar prop can be used to specify which calendar to use, along with the locale prop to set the locale of the date field.

You can use @internationalized/date to create calendar objects. In this example, we will use the islamic-umalqura calendar along with the ar-SA locale.

<script setup lang="ts">
import {
  createCalendar,
  IslamicUmalquraCalendar,
} from '@internationalized/date';
import DateField from './DateField.vue';

// This will import all calendars available.
// Resulting in a larger bundle size.
const calendar = createCalendar('islamic-umalqura');

// This will import only the Islamic Umalqura calendar.
// This allows tree-shaking, reducing the bundle size.
// const calendar = IslamicUmalquraCalendar;
</script>

<template>
  <DateField
    label="Hijri Date"
    :value="new Date('2025-02-11')"
    :calendar="calendar"
    locale="ar-SA"
  />
</template>

Value type with `calendar` prop

When using a non-Gregorian calendar system (like Islamic or Japanese calendars), the calendar composable will still use JavaScript’s native Date objects internally. This means that even though you may see dates displayed in your chosen calendar system, the actual value emitted by the component will be the equivalent Gregorian date.

For example, if you select “1 Muharram 1445” in the Islamic calendar, the emitted value will be a Date object representing “July 19, 2023” in the Gregorian calendar.

We’re interested in hearing from users who work with different calendar systems - how would you prefer to handle these date values? Please share your feedback with us.

Usage with Calendar Component

You can use the DateField component with the Calendar component to allow users to select a date. First check out the Calendar guide to build your own calendar component so that you can use it in the next example.
