How to use Moment.JS to check whether the current time is between 2 times

Say the current time is 09:34:00 (hh:mm:ss), and I have two other times in two variables:

var beforeTime = '08:34:00',
    afterTime = '10:34:00';

How do I use Moment.JS to check whether the current time is between beforeTime and afterTime?

I've seen isBetween(), and I've tried to use it like:

moment().format('hh:mm:ss').isBetween('08:27:00', '10:27:00')

but that doesn't work because as soon as I format the first (current time) moment into a string, it's no longer a moment object. I've also tried using:

moment('10:34:00', 'hh:mm:ss').isAfter(moment().format('hh:mm:ss')) && moment('08:34:00', 'hh:mm:ss').isBefore(moment().format('hh:mm:ss'))

but I get false, because again when I format the current time, it's no longer a moment.

How do I get this to work?

Solution 1:

• You can pass moment instances to isBetween()
• leave out the format() calls, what you want is to pass parse formats like int the first moment() of your second attempt.

That's all:

var format = 'hh:mm:ss'

// var time = moment() gives you current time. no format required.
var time = moment('09:34:00',format),
  beforeTime = moment('08:34:00', format),
  afterTime = moment('10:34:00', format);

if (time.isBetween(beforeTime, afterTime)) {

  console.log('is between')

} else {

  console.log('is not between')

}

// prints 'is between'

Solution 2:

I had to use isBetween and isSame in my case to cover the before and after time I used in the isBetween condition.

function getTimeCategory(time) {
  let timeCategory = '';
  const timeFormat = 'HH:mm:ss';

  if (
    time.isBetween(moment('00:00:00', timeFormat), moment('04:59:59', timeFormat)) ||
    time.isSame(moment('00:00:00', timeFormat)) ||
    time.isSame(moment('04:59:59', timeFormat))
  ) {
    timeCategory = 'DAWN';
  } else if (
    time.isBetween(moment('05:00:00', timeFormat), moment('11:59:59', timeFormat)) ||
    time.isSame(moment('05:00:00', timeFormat)) ||
    time.isSame(moment('11:59:59', timeFormat))
  ) {
    timeCategory = 'MORNING';
  } else if (
    time.isBetween(moment('12:00:00', timeFormat), moment('16:59:59', timeFormat)) ||
    time.isSame(moment('12:00:00', timeFormat)) ||
    time.isSame(moment('16:59:59', timeFormat))
  ) {
    timeCategory = 'NOON';
  } else if (
    time.isBetween(moment('17:00:00', timeFormat), moment('23:59:59', timeFormat)) ||
    time.isSame(moment('17:00:00', timeFormat)) ||
    time.isSame(moment('23:59:59', timeFormat))
  ) {
    timeCategory = 'NIGHT';
  }

  return timeCategory;
}

Solution 3:

I have use moment function combination isSameOrAfter and isSameOrBefore instead of isBetween.

if(moment(currentTime,'HH:mm:ss').isSameOrAfter(moment(shift_dayFrom,'HH:mm:ss')) && 
moment(currentTime,'HH:mm:ss').isSameOrAfter(moment(shift_dayTo,'HH:mm:ss')))
