Get month name from Date

Question

How can I generate the name of the month  e g  Oct October  from this date object in JavaScript   var objDate   new Date  10 11 2009

User · Answer

The natural format this days is to use Moment.js.

The way to get the month in a string format , is very simple in Moment.js no need to hard code the month names in your code: To get the current month and year in month name format and full year (May 2015) :

  moment(new Date).format("MMMM YYYY");

A quick hack I used which works well    x000D   x000D  const monthNumber   8  x000D  const yearNumber   2018  x000D  const date        Jan    Feb    Mar    Apr   x000D     May    Jun    Jul    Aug   x000D     Sep    Oct    Nov    Dec   monthNumber - 1  x000D            yearNumber    x000D   x000D  console log date   x000D   x000D   x000D

If you don t mind extending the Date prototype  and there are some good reasons to not want to do this   you can actually come up with a very easy method   Date prototype monthNames          January    February    March        April    May    June        July    August    September        October    November    December      Date prototype getMonthName   function         return this monthNames this getMonth        Date prototype getShortMonthName   function          return this getMonthName   substr 0  3          usage  var d   new Date    alert d getMonthName              October  alert d getShortMonthName         Oct    These functions will then apply to all javascript Date objects

I have a partial solution that I came up with  It uses a regular expression to extract the month and day name  But as I look through the Region and Language options  Windows  I realize that different cultures have different format order     maybe a better regular expression pattern could be useful   function testDateInfo             var months   new Array            var days   new Array            var workingDate   new Date            workingDate setHours 0  0  0  0           workingDate setDate 1           var RE   new RegExp    a-z      ig              -- get day names 0-6         for  var i   0  i  lt  7  i                   var day   workingDate getDay                  -- will eventually be in order             if  days day     undefined                  days day    workingDate toLocaleDateString   match RE  0               workingDate setDate workingDate getDate     1                       --get month names 0-11         for  var i   0  i  lt  12  i                  workingDate setMonth i               months push workingDate toLocaleDateString   match RE  1                      alert days join           n r     months join

You could just simply use Date toLocaleDateString   and parse the date wanted as parameter  x000D   x000D  const event   new Date Date UTC 2012  11  20  3  0  0     const options      year   numeric   month   short   day   numeric      console log event toLocaleDateString  de-DE   options       expected output  Donnerstag  20  Dezember 2012  console log event toLocaleDateString  en-US   options       US format       In case you only want the month console log event toLocaleDateString undefined    month   short      console log event toLocaleDateString undefined    month   long      x000D   x000D   x000D   You can find more information in the Firefox documentation

Here s a way that does not depend on a hard-coded array and supports multiple locales   If you need a whole array   var monthsLocalizedArray   function locale        var result           for var i   0  i  lt  12  i              result push new Date 2010 i  toLocaleString locale  month  long                return result       Usage   console log monthsLocalizedArray  en        - gt    January    February    March    April    May    June    July    August    September    October    November    December   console log monthsLocalizedArray  bg        - gt                                                                                                                           If you need only a selected month  faster    var monthLocalizedString   function month  locale        return new Date 2010 month  toLocaleString locale  month  long          Usage   console log monthLocalizedString 1   en        - gt  February console log monthLocalizedString 1   bg        - gt           console log monthLocalizedString 1   de        - gt  Februar   Tested and works fine on Chrome and IE 11  On mozilla some modifications are needed  because it returns the whole date

Just extending on the many other excellent answers - if you are using jQuery - you could just do something like    fn getMonthName   function date         var monthNames          January    February    March        April    May    June        July    August    September        October    November    December              return monthNames date getMonth           where date is equal to the var d   new Date somevalue   The primary advantage of this is per  nickf said about avoiding the global namespace

If you don t want to use an external library  or store an array of month names  or if the ECMAScript Internationalization API is not good enough because of browser compatibility you can always do it the old-fashioned way by extracting the info from the date output   var now   new Date    var monthAbbrvName   now toDateString   substring 4  7     This would give you the abbreviated month name  e g  Oct  I believe the date will come in all sorts of formats depending on the initialization and your locale so take a look at what toDateString   returns and recalculate your substring   values based on that

I heartily recommend the format function from  the moment js library  which you can use like this   moment   format  MMM         Apr  - current date moment new Date 2012  01  04   format  MMM         Feb  - from a local date moment utc new Date 2012  00  04  format  MMM        Jan  - from a UTC date   Use  MMMM  instead of  MMM  if you need the full name of the month  In addition to a lengthy list of other features  it has strong support for internationalization

You might use datejs to do that  Check the FormatSpecifiers  MMMM gives you the month s name   var objDate   new Date  10 11 2009    document write objDate toString  MMMM       And datejs got that localized for more than 150 locales  See here
