DateTimeFormatInfo.AbbreviatedMonthNames Property


The .NET API Reference documentation has a new home. Visit the .NET API Browser on to see the new experience.

Gets or sets a one-dimensional string array that contains the culture-specific abbreviated names of the months.

Namespace:   System.Globalization
Assembly:  mscorlib (in mscorlib.dll)

public string[] AbbreviatedMonthNames { get; set; }

Property Value

Type: System.String[]

A one-dimensional string array with 13 elements that contains the culture-specific abbreviated names of the months. For 12-month calendars, the 13th element of the array is an empty string. The array for InvariantInfo contains "Jan", "Feb", "Mar", "Apr", "May", "Jun", "Jul", "Aug", "Sep", "Oct", "Nov", "Dec", and "".

Exception Condition

The property is being set to null.


The property is being set to an array that is multidimensional or that has a length that is not exactly 13.


The property is being set and the DateTimeFormatInfo object is read-only.

If you set this property, the array must be one-dimensional with exactly 13 elements. Calendar objects accommodate calendars with 13 months. The first element (the element at index zero) represents the first month of the year defined by the Calendar property.

If you set the AbbreviatedMonthNames property, you must also set the AbbreviatedMonthGenitiveNames property. The AbbreviatedMonthNames and AbbreviatedMonthGenitiveNames properties are used to format dates using the following format strings:

  • A standard date and time format string that aliases a custom format string that includes the "MMM" format specifier.

  • A custom date and time format string that includes the "MMM" format specifier.

This property is affected if the value of the Calendar property changes. If the selected Calendar does not support abbreviated month names, the array contains the full month names.

The following example creates a read/write CultureInfo object that represents the English (United States) culture and assigns abbreviated genitive month names to its AbbreviatedMonthNames and AbbreviatedMonthGenitiveNames properties. It then displays the string representation of dates that include the abbreviated name of each month in the culture's supported calendar.

using System.Globalization;

public class Example
   public static void Main()
      CultureInfo ci = CultureInfo.CreateSpecificCulture("en-US");
      DateTimeFormatInfo dtfi = ci.DateTimeFormat;
      dtfi.AbbreviatedMonthNames = new string[] { "of Jan", "of Feb", "of Mar", 
                                                  "of Apr", "of May", "of Jun", 
                                                  "of Jul", "of Aug", "of Sep", 
                                                  "of Oct", "of Nov", "of Dec", "" };  
      dtfi.AbbreviatedMonthGenitiveNames = dtfi.AbbreviatedMonthNames;
      DateTime dat = new DateTime(2012, 5, 28);

      for (int ctr = 0; ctr < dtfi.Calendar.GetMonthsInYear(dat.Year); ctr++)
         Console.WriteLine(dat.AddMonths(ctr).ToString("dd MMM yyyy", dtfi));
// The example displays the following output:
//       28 of May 2012
//       28 of Jun 2012
//       28 of Jul 2012
//       28 of Aug 2012
//       28 of Sep 2012
//       28 of Oct 2012
//       28 of Nov 2012
//       28 of Dec 2012
//       28 of Jan 2013
//       28 of Feb 2013
//       28 of Mar 2013
//       28 of Apr 2013
