How can I get Month Name from Calendar?

Question

Is there a oneliner to get the name of the month when we know:

int monthNumber  = calendar.get(Calendar.MONTH)

Or what is the easiest way?

Answer 1

You can achieve it using SimpleDateFormat, which is meant to format date and times:

Calendar cal = Calendar.getInstance();
System.out.println(new SimpleDateFormat("MMM").format(cal.getTime()));

Answer 2

String getMonthForInt(int num) {
    String month = "wrong";
    DateFormatSymbols dfs = new DateFormatSymbols();
    String[] months = dfs.getMonths();
    if (num >= 0 && num <= 11) {
        month = months[num];
    }
    return month;
}

Answer 3

As simple as this

mCalendar = Calendar.getInstance();    
String month = mCalendar.getDisplayName(Calendar.MONTH, Calendar.LONG, Locale.getDefault());

Answer 4

This is the solution I came up with for a class project:

public static String theMonth(int month){
    String[] monthNames = {"January", "February", "March", "April", "May", "June", "July", "August", "September", "October", "November", "December"};
    return monthNames[month];
}

The number you pass in comes from a Calendar.MONTH call.

Answer 5

If you have multi-language interface, you can use getDisplayName to display the name of month with control of displaying language.

Here is an example of displaying the month name in English, French, Arabic and Arabic in specific country like "Syria":

Calendar c = Calendar.getInstance();
System.out.println(c.getDisplayName(Calendar.MONTH, Calendar.LONG, Locale.ENGLISH ) );
System.out.println(c.getDisplayName(Calendar.MONTH, Calendar.LONG, Locale.FRANCE ) );
System.out.println(c.getDisplayName(Calendar.MONTH, Calendar.LONG, new Locale("ar") ) );
System.out.println(c.getDisplayName(Calendar.MONTH, Calendar.LONG, new Locale("ar", "SY") ) );
System.out.println(c.getTime().toString());

The result is:

January
janvier
يناير
كانون الثاني
Sat Jan 17 19:31:30 EET 2015

Answer 6

SimpleDateFormat dateFormat = new SimpleDateFormat( "LLLL", Locale.getDefault() );
dateFormat.format( date );

For some languages (e.g. Russian) this is the only correct way to get the stand-alone month names.

This is what you get, if you use getDisplayName from the Calendar or DateFormatSymbols for January:

января (which is correct for a complete date string: "10 января, 2014")

but in case of a stand-alone month name you would expect:

январь

Answer 7

Joda-Time

How about using Joda-Time. It's a far better date-time API to work with (And January means january here. It's not like Calendar, which uses 0-based index for months).

You can use AbstractDateTime#toString( pattern ) method to format the date in specified format:

DateTime date = DateTime.now();
String month = date.toString("MMM");

Month Name From Number

If you want month name for a particular month number, you can do it like this:

int month = 3;
String monthName = DateTime.now().withMonthOfYear(month).toString("MMM");

Localize

The above approach uses your JVM’s current default Locale for the language of the month name. You want to specify a Locale object instead.

String month = date.toString( "MMM", Locale.CANADA_FRENCH );

Answer 8

Month::getDisplayName

Since Java 8, use the Month enum. The getDisplayName method automatically localizes the name of the month.

Pass:

• A TextStyle to determine how long or how abbreviated.
• A Locale to specify the human language used in translation, and the cultural norms used for abbreviation, punctuation, etc.

Example:

public static String getMonthStandaloneName(Month month) {
    return month.getDisplayName(
        TextStyle.FULL_STANDALONE, 
        Locale.getDefault()
    );
}

Answer 9

It might be an old question, but as a one liner to get the name of the month when we know the indices, I used

String month = new DateFormatSymbols().getMonths()[monthNumber - 1];

or for short names

String month = new DateFormatSymbols().getShortMonths()[monthNumber - 1];

Please be aware that your monthNumber starts counting from 1 while any of the methods above returns an array so you need to start counting from 0.

Answer 10

This code has language support. I had used them in Android App.

String[] mons = new DateFormatSymbols().getShortMonths();//Jan,Feb,Mar,... 

String[] months = new DateFormatSymbols().getMonths();//January,Februaty,March,...

Answer 11

I found this much easier(https://docs.oracle.com/javase/tutorial/datetime/iso/enum.html)

private void getCalendarMonth(Date date) {      
    Calendar calendar = Calendar.getInstance();
    calendar.setTime(date);
    Month month = Month.of(calendar.get(Calendar.MONTH));       
    Locale locale = Locale.getDefault();
    System.out.println(month.getDisplayName(TextStyle.FULL, locale));
    System.out.println(month.getDisplayName(TextStyle.NARROW, locale));
    System.out.println(month.getDisplayName(TextStyle.SHORT, locale));
}

Answer 12

You can get it one line like this:

String monthName = new DateFormatSymbols().getMonths()[cal.get(Calendar.MONTH)];

Answer 13

This works for me:

String getMonthName(int monthNumber) {
    String[] months = new DateFormatSymbols().getMonths();
    int n = monthNumber-1;
    return (n >= 0 && n <= 11) ? months[n] : "wrong number";
}

To returns "September" with one line:

String month = getMonthName(9);

Answer 14

One way:

We have Month API in Java (java.time.Month). We can get by using Month.of(month);

Here, the Month are indexed as numbers so either you can provide by Month.JANUARY or provide an index in the above API such as 1, 2, 3, 4.

Second way:

ZonedDateTime.now().getMonth();

This is available in java.time.ZonedDateTime.

Answer 15

Calender cal = Calendar.getInstance(Locale.ENGLISH)
String[] mons = new DateFormatSymbols(Locale.ENGLISH).getShortMonths();
int m = cal.get(Calendar.MONTH);
String mName = mons[m];

Answer 16

Easiest Way

import java.text.DateFormatSymbols;

int month = 3; // March
System.out.println(new DateFormatSymbols().getMonths()[month-1]);

Answer 17

It returns English name of the month. 04 returns APRIL and so on.

String englishMonth (int month){
        return Month.of(month);
    }

Answer 18

I created a Kotlin extension based on responses in this topic and using the DateFormatSymbols answers you get a localized response.

fun Date.toCalendar(): Calendar {
    val calendar = Calendar.getInstance()
    calendar.time = this
    return calendar
}


fun Date.getMonthName(): String {
    val month = toCalendar()[Calendar.MONTH]
    val dfs = DateFormatSymbols()
    val months = dfs.months
    return months[month]
}

Answer 19

import java.text.SimpleDateFormat;
import java.util.Calendar;


Calendar cal = Calendar.getInstance();
String currentdate=new SimpleDateFormat("dd-MMM").format(cal.getTime());

Answer 20

DateFormat date =  new SimpleDateFormat("dd/MMM/yyyy");
Date date1 = new Date();
System.out.println(date.format(date1));

Answer 21

For full name of month:

val calendar = Calendar.getInstance()
calendar.timeInMillis = date
return calendar.getDisplayName(Calendar.MONTH, Calendar.Long, Locale.ENGLISH)!!.toString()

And for short name of month:

val calendar = Calendar.getInstance()
calendar.timeInMillis = date
return calendar.getDisplayName(Calendar.MONTH, Calendar.SHORT, Locale.ENGLISH)!!.toString()

Answer 22

from the SimpleDateFormat java doc:

*         <td><code>"yyyyy.MMMMM.dd GGG hh:mm aaa"</code>
 *         <td><code>02001.July.04 AD 12:08 PM</code>
 *         <td><code>"EEE, d MMM yyyy HH:mm:ss Z"</code>
 *         <td><code>Wed, 4 Jul 2001 12:08:56 -0700</code>
