Date Field

Enables users to input specific dates within a designated field.

Birthday

	<script lang="ts">
  import { CalendarDate } from "@internationalized/date";
  import { DateField } from "bits-ui";
</script>
 
<DateField.Root minValue={new CalendarDate(2024, 8, 1)}>

  • add docs about leap years/birthdays and placeholder date

Before jumping into the DateField component, it's important to understand how dates and times are handled in Bits UI. You can learn more about this on the Dates page.

Structure

	<script lang="ts">
	import { DateField } from "$lib";
</script>
 
<DateField.Root>
	<DateField.Label>Check-in date</DateField.Label>
	<DateField.Input>
		{#snippet children({ segments })}
			{#each segments as { part, value }}
				<DateField.Segment {part}>
					{value}
				</DateField.Segment>
			{/each}
		{/snippet}
	</DateField.Input>
</DateField.Root>

Reusable Components

It's recommended to use the DateField primitives to build your own custom date field component that can be used throughout your application.

The following example shows how you might create a reusable MyDateField component that can be used throughout your application. For style inspiration, reference the featured demo at the top of this page.

MyDateField.svelte
	<script lang="ts">
	import { DateField, type WithoutChildrenOrChild } from "bits-ui";
 
	type Props = WithoutChildrenOrChild<DateField.RootProps> & {
		labelText: string;
	};
 
	let { value, placeholder, name, ...restProps }: Props = $props();
</script>
 
<DateField.Root bind:value bind:placeholder {name} {...restProps}>
	<DateField.Label>{labelText}</DateField.Label>
	<DateField.Input>
		{#snippet children({ segments })}
			{#each segments as { part, value }}
				<DateField.Segment {part}>
					{value}
				</DateField.Segment>
			{/each}
		{/snippet}
	</DateField.Input>
</DateField.Root>

We'll be using the following MyDateField component in the following demos and examples to prevent repeating the same code over and over.

Select a date

dd
yyyy
	<script lang="ts">
  import { DateField } from "bits-ui";
 
  let {
    labelText = "Select a date",
    value = $bindable(),
    placeholder = $bindable(),
    ...restProps
  }: DateField.RootProps & { labelText: string } = $props();
</script>
 
<DateField.Root bind:value bind:placeholder {...restProps}>
  <div class="flex w-full max-w-[280px] flex-col gap-1.5">
