<DateInput>
Ideal for editing dates, <DateInput> renders an HTML <input type="date"> element, that most browsers display as a  date picker.
The appearance of <DateInput> depends on the browser, and falls back to a text input on Safari. The date formatting in this input depends on the userβs locale.
React-admin also proposes a DateInput styled with Material UI documented at the end of this page.
Usage
import { DateInput } from 'react-admin';
<DateInput source="published_at" />
The field value must be a string using the pattern YYYY-MM-DD (ISO 8601), e.g. '2022-04-30'. The returned input value will also be in this format, regardless of the browser locale.
<DateInput> also accepts values that can be converted to a Date object, such as:
- a localized date string (e.g. 
'30/04/2022'), - an ISO date string (e.g. 
'2022-04-30T00:00:00.000Z'), - a 
Dateobject, or - a Linux timestamp (e.g. 
1648694400000). 
In these cases, <DateInput> will automatically convert the value to the YYYY-MM-DD format.
Note: This conversion may change the date because of timezones. For example, the date string '2022-04-30T00:00:00.000Z' in Europe may be displayed as '2022-04-29' in Honolulu. If this is not what you want, pass your own parse function to <DateInput>.
Props
<DateInput> accepts the common input props.
Validation
To validate that a date is before or after a given date, use the maxValue and minValue validators with a date string.
import { DateInput, minValue } from 'react-admin';
// requires dates after October 10th, 2022
<DateInput source="published" validate={minValue('2022-10-26')} />
Internationalization
It is not possible to customize the date format. Browsers use the user locale to display the date in the correct format.
If you need to render a UI despite the browser locale, MUI also proposes a Date Picker component, which is more customizable than the native date picker, but requires additional packages.
Material UI
React-admin Enterprise Edition proposes an alternative 
<DateInput> styled with Material UI.

This input also allows to specify the date format and the locale used. It is based on the MUI X Date/Time pickers.
Usage
import { DateInput } from '@react-admin/ra-form-layout';
import { Edit, SimpleForm } from 'react-admin';
export const EventEdit = () => (
    <Edit>
        <SimpleForm>
            <DateInput source="event_date" />
        </SimpleForm>
    </Edit>
);
<DateInput> will accept either a Date object or any string that can be parsed into a Date as value. It will return a Date object, or null if the date is invalid.
Tip: You can use the parse prop to change the format of the returned value. See Parsing the date/time as an ISO string for an example.
Props
| Prop | Required | Type | Default | Description | 
|---|---|---|---|---|
fullWidth | 
      - | boolean | - | If false, the input will not expand to fill the form width | 
    
helperText | 
      - | string | - | Text to be displayed under the input | 
mask | 
      - | string | - | Alias for the MUI format prop. Format of the date/time when rendered in the input. Defaults to localized format. | 
    
parse | 
      - | Function | value => value === '' ? null : value | 
      Callback taking the input value, and returning the value you want stored in the form state. | 
validate | 
      - | Function or Array | - | Validation rules for the input. See the Validation Documentation for details. | 
Except for the format prop (renamed mask), <DateInput> accepts the same props as the MUI X Date/Time pickers. They also accept the common input props.
Providing your own LocalizationProvider
MUI X Pickers need to be wrapped in a LocalizationProvider to work properly. <DateInput> already includes a default <LocalizationProvider> using the date-fns adapter and the enUS locale.
You can change the locale and the date format globally by wrapping the <Admin> with your own <LocalizationProvider>.
Here is how to set up the pickers to use the fr locale:
import { Admin, Resource } from 'react-admin';
import { LocalizationProvider } from '@mui/x-date-pickers';
import { AdapterDateFns } from '@mui/x-date-pickers/AdapterDateFns';
import { fr } from 'date-fns/locale/fr';
import { EventEdit } from './events';
export const App = () => (
    <LocalizationProvider dateAdapter={AdapterDateFns} adapterLocale={fr}>
        <Admin>
            <Resource name="events" edit={EventEdit} />
        </Admin>
    </LocalizationProvider>
);
Note: React Admin only supports the date-fns adapter for now.
Parsing the date/time as an ISO string
By default, <DateInput> stores the date/time as a Date object in the form state. If you wish to store the date/time as an ISO string instead (or any other format), you can use the parse prop.
<DateInput
    source="published"
    parse={(date: Date) => (date ? date.toISOString() : null)}
/>
