Issue with dateAdapter for specific language only

Question

I am using Angular material date picker and I have a problem with specific language only - ka. Take a look at the following example:

  constructor(
    private dateAdapter: DateAdapter<Date>,
    public noticesService:NoticesService, 
    public datepipe: DatePipe,
    private sanitizer: DomSanitizer,
    public router: Router) {
      this.dateAdapter.setLocale('fr');
    }

works as it should, take a look at the screenshot language changes and now the second language:

  constructor(
    private dateAdapter: DateAdapter<Date>,
    public noticesService:NoticesService, 
    public datepipe: DatePipe,
    private sanitizer: DomSanitizer,
    public router: Router) {
      this.dateAdapter.setLocale('ka');
    }

Language doesn't change and stays in English. This problem occurs only with ka language, all other languages work like a charm, I honestly have no clue what can be an issue here and how to edit things in order for it to work.

This is datepicker HTML template:

          <mat-form-field class="fullWidth padder forSelectLabel" appearance="outline">
            <mat-label>დაბადების თარიღი</mat-label>
            <div class="forSelect">
              <img class="doc-icon" style="max-width: 30px" [src]="iconPath + 'date.svg'">
              <input [(ngModel)]="dateOfBirth" placeholder="დაბადების თარიღი" autocomplete="off" matInput
                [matDatepicker]="picker" name="dateOfBirth">
              <mat-datepicker-toggle matSuffix [for]="picker"></mat-datepicker-toggle>
              <mat-datepicker #picker></mat-datepicker>
            </div>
          </mat-form-field>

Answer 1

Can you try with this instead?

this.dateAdapter.setLocale('ka-GE');
