Format Dates with Moment.js

Here we’ll see different methods that we can use with momentjs.

If we’ll use these format it’ll out like below.

m = moment('2013-03-01', 'YYYY-MM-DD')
m.format()                                  // "2013-03-01T00:00:00+01:00"
m.format('dddd')                       // "Friday"
m.format('MMM Do YY')          // "Mar 1st 13"
m.fromNow()                           // "7 years ago"
m.calendar()                           // "03/01/2013"

The format() function takes a string of tokens and replace it with the corresponding date value.

A token is a substring like ‘YYYY’ or ‘d’ that Moment knows to replace with a part of the date, like the year or the day of the month.

Following are few examples that are commonly used formatting tokens for dates:

  • YYYY: 4-digit year ‘2019’
  • YY: 2-digit year ’19’
  • MMMM: Full-length month ‘June’
  • MMM: 3 character month ‘Jun’
  • MM: Month of the year, zero-padded ’06’
  • M: Month of the year ‘6’
  • DD: Day of the month, zero-padded ’01’
  • D: Day of the month ‘1’
  • Do: Day of the month with numeric ordinal contraction ‘1st’

Sometimes you want to add text to the format string that you can do using following statement

m.format('[Today is ] Do [of] MMMM');    // 'Today is 1st of March'

Format Times with Moment.js

Momentjs also supports formatting times. The <strong>format()</strong> function is the most robust display option, so you can display either date or time or a combination of both.

For example, here’s how you can display a date’s time in 5:30am format:

const moment = require('moment');
const m = moment(new Date('2022/06/22 05:30:00'));
m.format('h:mma'); // '5:30am'

Here’s a list of commonly used time format tokens.

  • HH: hour of day from 0-24, zero-padded, '14'
  • H: hour of day from 0-24, '14'
  • hh: hour of day on 12-hour clock, zero-padded, '02'
  • h: hour of the day on 12 hour clock, '2'
  • mm: minute, zero-padded, '04'
  • m: minute, '4'
  • ss: second, zero-padded
  • s: second
  • A'AM' or 'PM'
  • a'am' or 'pm

Here’s some common date formats and how to express them in Moment format strings:

  • '14:04'HH:mm
  • '14:04:03'HH:mm:ss
  • '2:04pm'h:mma
  • '2:04 PM'h:mm A

Durations with Moment.js (Parse Date Time Ago)
