Try this:

<div *ngFor="let item of items">{{getDiffDate(item.dateStart, item.dateEnd)}}</div>

getDiffDate(dateStart:Date, dateEnd:Date){
   return dateEnd.getTime() - dateStart.getTime() //result in miliseconds. Just convert it to whatever you want
}

`1day = 24h = 24*60m = 24*60*60s = 24*60*60*1000ms`. Now you are having number of ms. – Duannx Jul 10 '17 at 06:27
