How to set the default date of ion-datetime is today and disable the days passed?

[kgaspar]

Think he means setting the minimum date to todays date.

        this.startDate = new Date().toISOString();
        this.minDate = new Date().toISOString();

and in the html

            <ion-datetime
                displayFormat="MMM DD, YYYY HH:mm"
                [min]="minDate"
                [(ngModel)]="startDate"
                >
            </ion-datetime>
