PrimeNG <p-calendar> error date.getMonth is not a function
It can't convert to Date from JSON automatically, you have to assign it yourself.
this.id = this.route.snapshot.paramMap.get('id');
if (this.id) {
this.service.get(this.id).take(1)
.subscribe(service => this.entry = { entryDate: new Date(service.entryDate) });
}
Your variable entryDate
is never assigned or used. You can remove it unless you want to have a reference to p-calendar component and have access to its' properties and methods. In that case you have to decorate it with an attribute like:
@ViewChild('entryDate')
entryDate: Calendar;
Note that the type is Calendar, not Date. It's a primeng type and should be imported from primeng

I am getting the error
core.es5.js:1020 ERROR Error: Uncaught (in promise): TypeError: date.getMonth is not a function
TypeError: date.getMonth is not a function
I get this error whenever I try to use 2 way data binding when I recevie my JSON object from my backend. My backend data type is a Date but it will not show backup in the p-calendar input. Please help!
{ "applicationId": 1, "entryDate": 1524665731000, "ongoingDescription": "<p>Ongoing entry should end in (5081421)</p>", "activeFlag": "Y" }
HTML
<div class="form-group"> <label>Date of the Ongoing Incident</label> <br> <p-calendar required [(ngModel)]="entry.entryDate" name="entryDate" #entryDate="ngModel" [showIcon]="true" [showTime]="true" dateFormat="mm/dd/y 'EST'" hourFormat="24"></p-calendar> <div class="alert alert-danger" *ngIf="entryDate.touched && !entryDate.valid" >The date and time of the incident are required</div> </div>
TS
entryDate: Date; entry = { } constructor(private service: OngoingService, private route: ActivatedRoute, private router: Router, private location: Location) { this.id = this.route.snapshot.paramMap.get('id'); if (this.id) this.service.get(this.id).take(1).subscribe(service => this.entry = service); } ngOnInit() { } ngAfterContentInit() { } ngAfterViewInit() { }
Any information will help
I tried to also assign the entryDate = new Date(); and entryDate = new Date(this.entryDate);
