Migration from v5 to v6

This guide describes the changes needed to migrate the Date & Time Pickers from v5 to v6.

Start using the alpha release

In package.json, change the version of the date pickers package to next.

-"@mui/x-date-pickers": "latest",
+"@mui/x-date-pickers": "next",

Using next ensures that it will always use the latest v6 alpha release, but you can also use a fixed version, like 6.0.0-alpha.0.

Since v6 is a major release, it contains some changes that affect the public API. These changes were done for consistency, improve stability and make room for new features. Below are described the steps you need to take to migrate from v5 to v6.

Run codemods

The preset-safe codemod will automatically adjust the bulk of your code to account for breaking changes in v6 for both the Date and Time Pickers and DataGrid. It should be only applied once per folder.

npx @mui/x-codemod v6.0.0/preset-safe <path>

Breaking changes that are handled by this codemod are denoted by a ✅ emoji in the table of contents on the right side of the screen.

If you have already applied the v6.0.0/preset-safe codemod, then you should not need to take any further action on these items.

All other changes must be handled manually.

Picker components rewrite

Update format of the `value` prop

Previously, it was possible to provide any format that your date management library was able to parse. For instance, you could pass value={new Date()} when using AdapterDayjs. This behavior brought a lot of confusion.

In v6, the format expected by the value prop is the same as for any other prop holding a date. Here is the syntax to initialize a date picker at the current date for each adapter:

// Date-fns
<DatePicker value={new Date()} />;

// Dayjs
import dayjs from 'dayjs';
<DatePicker value={dayjs()} />;

// Moment
import moment from 'moment';
<DatePicker value={moment()} />;

// Luxon
import { DateTime } from 'luxon';
<DatePicker value={DateTime.now()} />;

Drop `clock` in desktop mode

In desktop mode, the DateTimePicker and TimePicker components will not display the clock. This is the first step towards moving to a better implementation. The behavior on mobile mode is still the same. If you were relying on Clock Picker in desktop mode for tests—make sure to check testing caveats to choose the best replacement for it.

You can manually re-enable the clock using the new viewRenderers prop. The code below enables the Clock UI on all the DesktopTimePicker and DesktopDateTimePicker in your application.

Take a look at the default props via theme documentation for more information.

const theme = createTheme({
  components: {
    MuiDesktopNextTimePicker: {
      defaultProps: {
        viewRenderers: {
          hours: renderTimeViewClock,
          minutes: renderTimeViewClock,
          seconds: renderTimeViewClock,
        },
      },
    },
    MuiDesktopNextDateTimePicker: {
      defaultProps: {
        viewRenderers: {
          hours: renderTimeViewClock,
          minutes: renderTimeViewClock,
          seconds: renderTimeViewClock,
        },
      },
    },
  },
});

Date library and adapters

Do not import adapter from `@date-io`

In v5, it was possible to import adapters either from @date-io or @mui/x-date-pickers which were the same. In v6, the adapters are extended by @mui/x-date-pickers to support fields components. Which means adapters can not be imported from @date-io anymore. They need to be imported from @mui/x-date-pickers or @mui/x-date-pickers-pro. Otherwise, some methods will be missing. If you do not find the adapter you were using—there probably was a reason for it, but you can raise an issue expressing interest in it.

-import AdapterJalaali from '@date-io/jalaali';
+import { AdapterMomentJalaali } from '@mui/x-date-pickers-pro/AdapterMomentJalaali';

Increase Luxon minimal version

The v6 AdapterLuxon now requires luxon version 3.0.2 or higher in order to work.

Take a look at the Upgrading Luxon guide if you are using an older version.

View components

✅ Rename components

The view components allowing to pick a time, a date or parts of a date without an input have been renamed to better fit their usage:

-<CalendarPicker {...props} />
+<DateCalendar {...props} />

-<DayPicker {...props} />
+<DayCalendar {...props} />

-<CalendarPickerSkeleton {...props} />
+<DayCalendarSkeleton {...props} />

-<MonthPicker {...props} />
+<MonthCalendar {...props} />

-<YearPicker {...props} />
+<YearCalendar {...props} />

-<ClockPicker {...props} />
+<TimeClock {...props} />

Component names in the theme have changed as well:

-MuiCalendarPicker: {
+MuiDateCalendar: {

-MuiDayPicker: {
+MuiDayCalendar: {

-MuiCalendarPickerSkeleton: {
+MuiDayCalendarSkeleton: {

-MuiMonthPicker: {
+MuiMonthCalendar: {

-MuiYearPicker: {
+MuiYearCalendar: {

-MuiClockPicker: {
+MuiTimeClock: {

✅ Rename `date` prop to `value`

The date prop has been renamed value on MonthCalendar, YearCalendar, TimeClock, and DateCalendar (components renamed in previous section):

-<MonthPicker date={dayjs()} />
+<MonthCalendar value={dayjs()} />

-<YearPicker date={dayjs()} />
+<YearCalendar value={dayjs()} />

-<ClockPicker date={dayjs()} />
+<TimeClock value={dayjs()} />

-<CalendarPicker date={dayjs()} />
+<DateCalendar value={dayjs()} />

Use the 12h/24h format from the locale as the default value of the `ampm` prop on `TimeClock`

The default value of the ampm prop changed from false to utils.is12HourCycleInCurrentLocale(). It means that the TimeClock component will use a 12h time format for locales where the time is usually displayed with a 12h format.

If you want to keep the previous behavior, you just have to set the ampm prop to false (components renamed in previous section):

- <ClockPicker />
+ <TimeClock ampm={false} />

Localization

✅ Rename localization props

The props used to set the text displayed in the pickers have been replaced by keys inside the localeText prop:

Removed prop	Property in the new `localText` prop
`endText`	`end`
`getClockLabelText`	`clockLabelText`
`getHoursClockNumberText`	`hoursClockNumberText`
`getMinutesClockNumberText`	`minutesClockNumberText`
`getSecondsClockNumberText`	`secondsClockNumberText`
`getViewSwitchingButtonText`	`calendarViewSwitchingButtonAriaLabel`
`leftArrowButtonText`	`openPreviousView` (or `previousMonth` when the button changes the visible month)
`rightArrowButtonText`	`openNextView` (or `nextMonth` when the button changes the visible month)
`startText`	`start`

For instance if you want to replace the startText / endText

 <DateRangePicker
-  startText="From"
-  endText="To"
+  localeText={{
+    start: 'From',
+    end: 'To',
+  }}
 />

✅ Rename `locale` prop on `LocalizationProvider`

The locale prop of the LocalizationProvider component have been renamed adapterLocale:

 <LocalizationProvider
   dateAdapter={AdapterDayjs}
-  locale="fr"
+  adapterLocale="fr"
 >
   {children}
 </LocalizationProvider

Component slots (custom sub-components)

Toolbar (`ToolbarComponent`)

The ToolbarComponent has been replaced by a Toolbar component slot. You can find more information about this pattern in the MUI Base documentation:
```
 // Same on all other pickers
 <DatePicker
-  ToolbarComponent: MyToolbar,
+  components={{ Toolbar: MyToolbar }}
 />
```

The toolbarPlaceholder and toolbarFormat props have been moved to the toolbar component props slot:

 // Same on all other pickers
 <DatePicker
-  toolbarPlaceholder="__"
-  toolbarFormat="DD / MM / YYYY"
+  componentsProps={{
+    toolbar: {
+      toolbarPlaceholder: "__",
+      toolbarFormat: "DD / MM / YYYY",
+    }
+  }}
 />

The toolbarTitle prop has been moved to the localization object:

 // Same on all other pickers
 <DatePicker
-  toolbarTitle="Title"
+  localeText={{ toolbarTitle: "Title" }}
 />

The toolbar related translation keys have been renamed to better fit their usage:

 // Same on all other pickers
 <DatePicker
  localeText={{
-    datePickerDefaultToolbarTitle: 'Date Picker',
+    datePickerToolbarTitle: 'Date Picker',

-    timePickerDefaultToolbarTitle: 'Time Picker',
+    timePickerToolbarTitle: 'Time Picker',

-    dateTimePickerDefaultToolbarTitle: 'Date Time Picker',
+    dateTimePickerToolbarTitle: 'Date Time Picker',

-    dateRangePickerDefaultToolbarTitle: 'Date Range Picker',
+    dateRangePickerToolbarTitle: 'Date Range Picker',
  }}
 />

The onChange / openView props on the toolbar have been renamed to onViewChange / view.

 const CustomToolbarComponent = props => (
   <div>
-    <button onChange={() => props.onChange('day')}>Show day view</button>
+    <button onClick={() => props.onViewChange('day')}>Show day view</button>
-    <div>Current view: {props.openView}</div>
+    <div>Current view: {props.view}</div>
   </div>
 )
 <DatePicker
-  ToolbarComponent={CustomToolbarComponent}
+  components={{
+    Toolbar: CustomToolbarComponent
+  }}
 />

The currentlySelectingRangeEnd / setCurrentlySelectingRangeEnd props on the Date Range Picker toolbar have been renamed to rangePosition / onRangePositionChange.

 const CustomToolbarComponent = props => (
   <div>
-    <button onChange={() => props.setCurrentlySelectingRangeEnd('end')}>Edit end date</button>
+    <button onClick={() => props.onRangePositionChange('end')}>Edit end date</button>
-    <div>Is editing end date: {props.currentlySelectingRangeEnd === 'end'}</div>
+    <div>Is editing end date: {props.rangePosition === 'end'}</div>
   </div>
 )
 <DateRangePicker
-  ToolbarComponent={CustomToolbarComponent}
+  components={{
+    Toolbar: CustomToolbarComponent
+  }}
 />

Tabs

The hideTabs and timeIcon props have been moved to tabs component props. The dateRangeIcon prop has been renamed to dateIcon and moved to tabs component props.

 // Same on all other Date Time picker variations
 <DateTimePicker
-  hideTabs={false}
-  dateRangeIcon={<LightModeIcon />}
-  timeIcon={<AcUnitIcon />}
+  componentsProps={{
+    tabs: {
+      hidden: false,
+      dateIcon: <LightModeIcon />,
+      timeIcon: <AcUnitIcon />,
+    }
+  }}
 />

The onChange prop on DateTimePickerTabs component has been renamed to onViewChange to better fit its usage:

 <DateTimePickerTabs
-  onChange={() => {}}
+  onViewChange={() => {}}
 />

 const CustomTabsComponent = props => (
   <div>
-    <button onClick={() => props.onChange('day')}>Show day view</button>
+    <button onClick={() => props.onViewChange('day')}>Show day view</button>
   </div>
 )
 <DateTimePicker
   components={{
     Tabs: CustomTabsComponent
   }}
 />

Action bar

The action prop of the actionBar slot is no longer supporting a callback. Instead, you can pass a callback at the slot level

 <DatePicker
   componentsProps={{
-     actionBar: {
-       actions: (variant) => (variant === 'desktop' ? [] : ['clear']),
-     },
+     actionBar: ({ wrapperVariant }) => ({
+       actions: wrapperVariant === 'desktop' ? [] : ['clear'],
+     }),
   }}
 />

Day (`renderDay`)

The renderDay prop has been replaced by a Day component slot on all date, date time and date range pickers:

 <DatePicker
-  renderDay={(_, dayProps) => <CustomDay {...dayProps} />}
+  components={{ Day: CustomDay }}
 />

The selectedDays prop have been removed from the Day component. If you need to access it, you can control the value and pass it to the slot using componentsProps:

function CustomDay({ selectedDay, ...other }) {
  // do something with 'selectedDay'
  return <PickersDay {...other} />;
}

function App() {
  const [value, setValue] = React.useState(null);

  return (
    <DatePicker
      value={value}
      onChange={(newValue) => setValue(newValue)}
      components={{ Day: CustomDay }}
      componentsProps={{
        day: { selectedDay: value },
      }}
    />
  );
}

Popper (`PopperProps`)

The PopperProps prop has been replaced by a popper component props on all responsive and desktop pickers:

 <DatePicker
-  PopperProps={{ onClick: handleClick }}
+  componentsProps={{ popper: { onClick: handleClick }}}
 />

Desktop transition (`TransitionComponent`)

The TransitionComponent prop has been replaced by a DesktopTransition component slot on all responsive and desktop pickers:
```
 <DatePicker
-  TransitionComponent={Fade}
+  components={{ DesktopTransition: Fade }}
 />
```

Dialog (`DialogProps`)

The DialogProps prop has been replaced by a dialog component props on all responsive and mobile pickers:

 <DatePicker
-  DialogProps={{ backgroundColor: 'red' }}
+  componentsProps={{ dialog: { backgroundColor: 'red }}}
 />

Desktop paper (`PaperProps`)

The PaperProps prop has been replaced by a desktopPaper component props on all responsive and desktop pickers:

 <DatePicker
-  PaperProps={{ backgroundColor: 'red' }}
+  componentsProps={{ desktopPaper: { backgroundColor: 'red }}}
 />

Desktop TrapFocus (`TrapFocusProp`)

The TrapFocusProps prop has been replaced by a desktopTrapFocus component props on all responsive and desktop pickers:

 <DatePicker
-  TrapFocusProps={{ isEnabled: () => false }}
+  componentsProps={{ desktopTrapFocus: { isEnabled: () => false }}}
 />

Paper Content

The PaperContent / paperContent component slot and component props slot have been removed.

You can use the new Layout component slot. The main difference is that you now receive the various parts of the UI instead of a single children prop:

+import { usePickerLayout } from '@mui/x-date-pickers/PickersLayout';

 function MyCustomLayout (props) {
-  const { children } = props;
-
-  return (
-    <React.Fragment>
-      {children}
-      <div>Custom component</div>
-    </React.Fragment>
-  );
+  const { toolbar, tabs, content, actionBar} = usePickerLayout(props);
+
+  return (
+    <PickersLayoutRoot>
+      {toolbar}
+      {content}
+      {actionBar}
+      <div>Custom component</div>
+    </PickersLayoutRoot>
+  );
 }

 function App() {
   return (
     <DatePicker
        components={{
-         PaperContent: MyCustomLayout,
+         Layout: MyCustomLayout,
        }}
     />
   );
 }

Left arrow button

The component slot LeftArrowButton has been renamed PreviousIconButton on all pickers:

 <DatePicker
   components={{
-    LeftArrowButton: CustomButton,
+    PreviousIconButton: CustomButton,
   }}

   componentsProps={{
-    leftArrowButton: {},
+    previousIconButton: {},
   }}
 />

Right arrow button

The component slot RightArrowButton has been renamed NextIconButton on all pickers:

 <DatePicker
   components={{
-    RightArrowButton: CustomButton,
+    NextIconButton: CustomButton,
   }}

   componentsProps={{
-    rightArrowButton: {},
+    nextIconButton: {},
   }}
 />

Rename remaining `private` components

The four components prefixed with Private are now stable. These components were renamed:

PrivatePickersMonth -> MuiPickersMonth
PrivatePickersSlideTransition -> MuiPickersSlideTransition
PrivatePickersToolbarText -> MuiPickersToolbarText
PrivatePickersYear -> MuiPickersYear

Manual style overriding will need to use updated classes:

-.PrivatePickersMonth-root {
+.MuiPickersMonth-root {

-.PrivatePickersSlideTransition-root {
+.MuiPickersSlideTransition-root {

-.PrivatePickersToolbarText-root {
+.MuiPickersToolbarText-root {

-.PrivatePickersYear-root {
+.MuiPickersYear-root {

Component name changes are also reflected in themeAugmentation:

 const theme = createTheme({
   components: {
-    PrivatePickersMonth: {
+    MuiPickersMonth: {
       // overrides
     },
-    PrivatePickersSlideTransition: {
+    MuiPickersSlideTransition: {
       // overrides
     },
-    PrivatePickersToolbarText: {
+    MuiPickersToolbarText: {
       // overrides
     },
-    PrivatePickersYear: {
+    MuiPickersYear: {
       // overrides
     },
   },
 });
