Issue with default date not functioning in Primeng's p-calendar module

I'm having trouble setting a default date in the datepicker. I attempted to use the defaultDate property of p-calendar, here's what I did:

<p-calendar placeholder="mm/dd/yyyy"
name="deadline" 
required 
[(ngModel)]="deadline" 
#deadline="ngModel" 
[showIcon]="true" 
showTime="showTime" 
hourFormat="12"
[defaultDate]="defaultDate">

Here's my Component.ts code:

public defaultDate: Date = new Date();
ngOnInit() {
    this.defaultDate.setDate(this.defaultDate.getDate() - 5);
}

Unfortunately, the above solution isn't working as expected. Can anyone provide assistance with this issue?

//deadline: Date = new Date(0);
deadline: Date;
defaultDate: Date = new Date("January 31 1980 12:30");

ngOnInit() {
   //if (this.deadline == undefined)
   //    this.deadline = new Date("June 30 1966 12:30");
}

As highlighted in the reported problem, the defaultDate property is meant to display the month and year when the field is first opened without any value.

It's important to note that defaultDate should not be used to set a specific date; it is only intended for scenarios where the ngModel is empty. To establish the initial displayed date, consider using ngModel instead of defaultDate.

For effective binding with your default date, it is recommended to utilize ngModel as explained in the following link: Open Link

In your specific scenario, the code snippet below should be sufficient:

<p-calendar placeholder="mm/dd/yyyy"
name="deadline" 
required 
[(ngModel)]="deadline" 
#deadline="ngModel" 
[showIcon]="true" 
showTime="showTime" 
hourFormat="12"
[defaultDate]=deadline>

Here is the code snippet I used in my project:

<p-calendar [dateFormat]="'dd/mm/yy'" [maxDate]="minDate" [defaultDate]="minDate" [(ngModel)]="date" [iconDisplay]="'input'" [showIcon]="true"  placeholder="JJ/MM/YYYY" id="date" ></p-calendar>

This is the TypeScript code I used to handle the date input:

export class DateFormPageComponent {
  date: Date | undefined;
  currentDate = new Date();
  minDate :Date = new Date(this.currentDate.getFullYear()-13, this.currentDate.getMonth(), this.currentDate.getDate());

  constructor(private router: Router, private route: ActivatedRoute) {
  }
}

When it comes to the [defaultDate] attribute, make sure you are using JavaScript Date instances. I encountered some difficulties when trying to use a getter method with defaultDate. It's important to note that your component property should be directly linked to defaultDate—avoid using getters, observables, or pipes as they may lead to complications.

In previous versions of PrimeNG, getters functioned properly with defaultDate. However, in the most recent version, a direct property from the component is now required.
