Datepicker in angular shows 0 thursday 0

Expected behavior It should shows the actual day or it should be a file dot be set for s default value, i don't want to set my variable (that I use in the ngModel) since this data can be also null. Actual behavior

It shows 0 Thursday 0 in the data picker header.
