Как найти даты, которые до 7-14 дней до сих пор

У меня есть массив, полный дат. Мне нужно сосчитать все даты старше 7 дней и моложе 14 до сих пор.

Пример: 

Today is 25/06/2019
Date1: 17/06/2019 - Correct
Date2: 23/06/2019 - Incorrect

Для этого я планировал использовать moment.js

Даты в массиве имеют формат ММ / ДД / ГГГГ ЧЧ: мм: сс 

var res = {sevendays:0};
const morethan7 = moment.utc().add(7, 'day').endOf('day');
const lessthan14 = moment.utc().add(14, 'day').endOf('day');


agedArray.forEach((date)=>{
    var agedtime = moment.utc(date, "MM/DD/YYYY HH:mm:ss");

    if ((agedtime.isBetween(morethan7)) && (agedtime.isBefore(lessthan14)) )
        res.sevendays++;

К сожалению, результат равен 0. Я считаю, что мне нужно указать сегодня, но понятия не имею, как это сделать.

Edit1: agedArray:

Вы прибываете по методу .add, но вам нужна старая дата.

Вместо этого используйте .subtract.

например, 

const morethan7 = moment().subtract(7, 'day');
const lessthan14 = moment().subtract(14, 'day');

И, как говорит @Cid, замените условие if на: 

if (agedtime.isBetween(morethan7, lessthan14))

Есть ли причина, простой JavaScript Array.prototype.filter() не будет работать для вас?
