Namespace:  System
Assembly:  mscorlib (in mscorlib.dll)
public int Month { get; }

Property Value

Type: System.Int32
The month in which the time change occurs.

Valid values for the Month property range from 1 to 12.

The Month property is used for both fixed-date and floating-date rules.

The following example enumerates the time zones found on the local computer and displays transition time information for all floating-date transitions. The time information includes the month in which the time change occurs.

private enum WeekOfMonth
{
   First = 1,
   Second = 2,
   Third = 3,
   Fourth = 4,
   Last = 5
}

private void GetFloatingTransitionTimes()
{
   ReadOnlyCollection<TimeZoneInfo> timeZones = TimeZoneInfo.GetSystemTimeZones();
   foreach (TimeZoneInfo zone in timeZones)
   {
      TimeZoneInfo.AdjustmentRule[] adjustmentRules = zone.GetAdjustmentRules();
      DateTimeFormatInfo dateInfo = CultureInfo.CurrentCulture.DateTimeFormat;
      foreach (TimeZoneInfo.AdjustmentRule adjustmentRule in adjustmentRules)
      {
         TimeZoneInfo.TransitionTime daylightStart = adjustmentRule.DaylightTransitionStart;
         if (! daylightStart.IsFixedDateRule)
            Console.WriteLine("{0}, {1:d}-{2:d}: Begins at {3:t} on the {4} {5} of {6}.", 
                              zone.StandardName, 
                              adjustmentRule.DateStart, 
                              adjustmentRule.DateEnd,                                 
                              daylightStart.TimeOfDay, 
                              ((WeekOfMonth)daylightStart.Week).ToString(),  
                              daylightStart.DayOfWeek.ToString(),
                              dateInfo.GetMonthName(daylightStart.Month));

         TimeZoneInfo.TransitionTime daylightEnd = adjustmentRule.DaylightTransitionEnd;
         if (! daylightEnd.IsFixedDateRule)
            Console.WriteLine("{0}, {1:d}-{2:d}: Ends at {3:t} on the {4} {5} of {6}.", 
                              zone.StandardName, 
                              adjustmentRule.DateStart, 
                              adjustmentRule.DateEnd,                                 
                              daylightEnd.TimeOfDay, 
                              ((WeekOfMonth)daylightEnd.Week).ToString(),  
                              daylightEnd.DayOfWeek.ToString(), 
                              dateInfo.GetMonthName(daylightEnd.Month));
      }
   }   
}
