I know I can do anything and some more envolving Dates with momentjs. But embarrassingly, I\'m having a hard time trying to do something that seems simple: geting the differ

Answer 1

If you want a localized number of days between two dates (startDate, endDate):

var currentLocaleData = moment.localeData("en");
var duration = moment.duration(endDate.diff(startDate));
var nbDays = Math.floor(duration.asDays()); // complete days
var nbDaysStr = currentLocaleData.relativeTime(returnVal.days, false, "dd", false);

nbDaysStr will contain something like '3 days';

See https://momentjs.com/docs/#/i18n/changing-locale/ for information on how to display the amount of hours or month, for example.
