# Date input (UI SDK): Unavailable dates

> `unavailable` takes ISO dates, `{ from, to }` ranges, weekdays or a function, and a date on one is invalid.

## Add this example

```bash

  return day === 0 || day === 6
}

function UiSdkDateInputUnavailable() {
  const [date, setDate] = React.useState<string | null>("2026-11-02")
  const weekend = date !== null && isWeekend(date)

  return (
    <div className="flex w-full max-w-44 flex-col gap-2">
      <Label id="delivery-date">Delivery date</Label>
      <DateInput
