const start = moment().subtract(1, 'days');
const end = new Date();
const actual = moment().subtract(1, 'hours');
const test = moment(actual).isBetween(start, end);
console.log(test);
  
// moment version < 2.13.0.
var startDate = new Date(2013, 1, 12)
  , endDate   = new Date(2013, 1, 15)
  , date  = new Date(2013, 2, 15)
  , range = moment().range(startDate, endDate);
range.contains(date);

Example 4: calculate time difference in hrs moment

var duration = moment.duration(end.diff(startTime));
var hours = duration.asHours();

Example 5: moment js date between two dates

target.isBetween(start, finish, 'days', '()') // default exclusive
target.isBetween(start, finish, 'days', '(]') // right inclusive
target.isBetween(start, finish, 'days', '[)') // left inclusive
target.isBetween(start, finish, 'days', '[]') // all inclusive
