Answer 1

You just need to provide a custom MAT_DATE_FORMATS

export const APP_DATE_FORMATS = {
    parse: {dateInput: {month: 'short', year: 'numeric', day: 'numeric'}},
    display: {
        dateInput: {month: 'short', year: 'numeric', day: 'numeric'},
        monthYearLabel: {year: 'numeric'}
    }
};

and add it to providers.

providers: [{
   provide: MAT_DATE_FORMATS, useValue: APP_DATE_FORMATS
}]

Working code

This is work for me!

import {Component} from '@angular/core';
import {FormControl} from '@angular/forms';
import {MomentDateAdapter, MAT_MOMENT_DATE_ADAPTER_OPTIONS} from '@angular/material-moment-adapter';
import {DateAdapter, MAT_DATE_FORMATS, MAT_DATE_LOCALE} from '@angular/material/core';

// Depending on whether rollup is used, moment needs to be imported differently.
// Since Moment.js doesn't have a default export, we normally need to import using the `* as`
// syntax. However, rollup creates a synthetic default module and we thus need to import it using
// the `default as` syntax.
import * as _moment from 'moment';
// tslint:disable-next-line:no-duplicate-imports
import {default as _rollupMoment} from 'moment';

const moment = _rollupMoment || _moment;

// See the Moment.js docs for the meaning of these formats:
// https://momentjs.com/docs/#/displaying/format/
export const MY_FORMATS = {
parse: {
    dateInput: 'LL',
},
display: {
    dateInput: 'LL',
    monthYearLabel: 'MMM YYYY',
    dateA11yLabel: 'LL',
    monthYearA11yLabel: 'MMMM YYYY',
},
};

/** @title Datepicker with custom formats */
@Component({
selector: 'datepicker-formats-example',
templateUrl: 'datepicker-formats-example.html',
providers: [
    // `MomentDateAdapter` can be automatically provided by importing `MomentDateModule` in your
    // application's root module. We provide it at the component level here, due to limitations of
    // our example generation script.
    {
    provide: DateAdapter,
    useClass: MomentDateAdapter,
    deps: [MAT_DATE_LOCALE, MAT_MOMENT_DATE_ADAPTER_OPTIONS]
    },

    {provide: MAT_DATE_FORMATS, useValue: MY_FORMATS},
],
})
export class YourDatepickerUsedComponent {
    date = new FormControl(moment());
}
