# DateTime.IsLeapYear(Int32) Method

## Definition

지정된 연도가 윤년인지를 나타내는 표시를 반환합니다.Returns an indication whether the specified year is a leap year.

``````public:
static bool IsLeapYear(int year);``````
``public static bool IsLeapYear (int year);``
``static member IsLeapYear : int -> bool``
``Public Shared Function IsLeapYear (year As Integer) As Boolean``

#### Parameters

year
Int32

4자리 연도입니다.A 4-digit year.

#### Returns

Boolean

`true`가 윤년이면 `year`이고, 그렇지 않으면 `false`입니다.`true` if `year` is a leap year; otherwise, `false`.

#### Exceptions

`year`가 1보다 작거나 9999보다 큽니다.`year` is less than 1 or greater than 9999.

## Examples

다음 예제에서는 IsLeapYear 메서드를 사용 하 여 1994과 2014 사이의 연도를 윤년으로 확인 합니다.The following example uses the IsLeapYear method to determine which years between 1994 and 2014 are leap years. 또한이 예제에서는 AddYears 메서드를 사용 하 여 윤년에 연도를 더할 때의 결과를 보여 줍니다.The example also illustrates the result when the AddYears method is used to add a year to a leap day.

``````using System;

public class IsLeapYear
{
public static void Main()
{
for (int year = 1994; year <= 2014; year++)
{
if (DateTime.IsLeapYear(year))
{
Console.WriteLine("{0} is a leap year.", year);
DateTime leapDay = new DateTime(year, 2, 29);
Console.WriteLine("   One year from {0} is {1}.",
leapDay.ToString("d"),
nextYear.ToString("d"));
}
}
}
}
// The example produces the following output:
//       1996 is a leap year.
//          One year from 2/29/1996 is 2/28/1997.
//       2000 is a leap year.
//          One year from 2/29/2000 is 2/28/2001.
//       2004 is a leap year.
//          One year from 2/29/2004 is 2/28/2005.
//       2008 is a leap year.
//          One year from 2/29/2008 is 2/28/2009.
//       2012 is a leap year.
//          One year from 2/29/2012 is 2/28/2013.

## Remarks

`year`은 4 자리 밑수 10 숫자로 지정 됩니다. 예를 들면 1996입니다.`year` is specified as a 4-digit base 10 number; for example, 1996.

`year`은 항상 양력에서 연도로 해석 됩니다.`year` is always interpreted as a year in the Gregorian calendar. 특정 연도가 다른 달력에서 윤년 인지 여부를 확인 하려면 해당 달력 개체의 `IsLeapYear` 메서드를 호출 합니다.To determine whether a particular year was a leap year in some other calendar, call that calendar object's `IsLeapYear` method.
