属性

次の例でDateTimeは、 DateTime.Nowプロパティ、 DateTimeコンストラクター、およびペルシャ暦のToDateTime(Int32, Int32, Int32, Int32, Int32, Int32, Int32)メソッドを使用してオブジェクトをインスタンス化します。The following example instantiates DateTime objects by using the DateTime.Now property, a DateTime constructor, and the Persian calendar's ToDateTime(Int32, Int32, Int32, Int32, Int32, Int32, Int32) method. 次に、これらの日付がグレゴリオ暦とペルシャ暦の両方に表示されます。It then displays these dates in both the Gregorian and Persian calendars. また、ペルシャ暦の日付範囲も表示されます。It also displays the date range of the Persian calendar.

注釈

ペルシャ暦は、ペルシャ語が話されるほとんどの国/地域で使用されますが、一部の地域では異なる月名が使用されます。The Persian calendar is used in most countries/regions where Persian is spoken, although some regions use different month names. ペルシャ暦は、イランとアフガニスタンの公式の暦であり、カザフスタンやタジキスタンなどの地域の代替暦の1つです。The Persian calendar is the official calendar of Iran and Afghanistan, and it is one of the alternative calendars in regions such as Kazakhstan and Tajikistan.

注意

PersianCalendar クラスや .NET Framework のその他のカレンダー クラスの使用方法の詳細については、「カレンダーの使用」を参照してください。For information about using the PersianCalendar class and the other calendar classes in the .NET Framework, see Working with Calendars.

ペルシャ暦の日付は、Hijra の年から始まります。これは、紀元622に対応しています。Dates in the Persian calendar start from the year of the Hijra, which corresponds to 622 C.E. とは、Muhammad (PBUH) が Mecca から Medina に移行された年です。and is the year when Muhammad (PBUH) migrated from Mecca to Medina. たとえば、西暦2002年3月21日の日付For example, the date March 21, 2002 C.E. 1381キリストの Farvardeen の月の最初の日に相当します。corresponds to the first day of the month of Farvardeen in the year 1381 Anno Persico.

ペルシャ暦は、太陽の年に基づいており、約365日の長さになっています。The Persian calendar is based on a solar year and is approximately 365 days long. 年は4つの季節を通過し、新しい年は、太陽が、地球の中央から見たように、南部の民族から北の単位にクロスされたときに開始します。A year cycles through four seasons, and a new year begins when the sun appears to cross the equator from the southern hemisphere to the northern hemisphere as viewed from the center of the Earth. 新しい年は、Farvardeen の月の最初の日を示しています。これは、北の単位で spring の最初の日になります。The new year marks the first day of the month of Farvardeen, which is the first day of spring in the northern hemisphere.

ペルシャ暦の最初の6か月はそれぞれ31日、次の5か月は30日、過去1か月は平年には29日、閏年は30日です。Each of the first six months in the Persian calendar has 31 days, each of the next five months has 30 days, and the last month has 29 days in a common year and 30 days in a leap year. 閏年は、33で割った剰余が1、5、9、13、17、22、26、または30である年です。A leap year is a year that, when divided by 33, has a remainder of 1, 5, 9, 13, 17, 22, 26, or 30. たとえば、1370年はうるう年であるため、33で割った剰余は17になります。For example, the year 1370 is a leap year because dividing it by 33 yields a remainder of 17. 33年のサイクルごとに約8個の閏年があります。There are approximately eight leap years in every 33-year cycle.

PersianCalendar クラスと .NET Framework バージョンThe PersianCalendar class and .NET Framework versions

以降では、クラスPersianCalendarは監視アルゴリズムではなく、イスラム暦の太陽天文学アルゴリズムを使用して日付を計算します。 .NET Framework 4.6.NET Framework 4.6Starting with the .NET Framework 4.6.NET Framework 4.6, the PersianCalendar class uses the Hijri solar astronomical algorithm rather than an observational algorithm to calculate dates. これによりPersianCalendar 、イランとアフガニスタンで使用されるペルシャ暦との実装が一貫しています。これは、ペルシャ暦が最も広く使用されている2つの国です。This makes the PersianCalendar implementation consistent with the Persian calendar in use in Iran and Afghanistan, the two countries in which the Persian calendar is in most widespread use. この変更は、 .NET Framework 4.6.NET Framework 4.6がインストールされている場合、.NET Framework 4 以降で実行されているすべてのアプリに影響します。The change affects all apps running on the .NET Framework 4 or later if the .NET Framework 4.6.NET Framework 4.6 is installed.

変更されたアルゴリズムの結果として、次のようになります。As a result of the changed algorithm:

  • 2つのアルゴリズムは、グレゴリオ暦で1800と2123の間の日付を変換するときに、同一の結果を返す必要があります。The two algorithms should return identical results when converting dates between 1800 and 2123 in the Gregorian calendar.

  • 2つのアルゴリズムでは、グレゴリオ暦で1800より前と2123後の日付を変換すると、異なる結果が返される場合があります。The two algorithms may return different results when converting dates before 1800 and after 2123 in the Gregorian calendar.

  • グレゴリオ暦で、プロパティ値がグレゴリオ暦の0622年3月21日から0622年3月22日に変更されました。MinSupportedDateTimeThe MinSupportedDateTime property value has changed from March 21, 0622 in the Gregorian calendar to March 22, 0622 in the Gregorian calendar.

  • ペルシャ暦の9378年の10番目の日から、ペルシャ暦の9378年の第10月の13日にプロパティ値が変更されました。MaxSupportedDateTimeThe MaxSupportedDateTime property value has changed from the 10th day of the 10th month of the year 9378 in the Persian calendar to the 13th day of the 10th month of the year 9378 in the Persian calendar.

  • メソッドIsLeapYearは、以前とは異なる結果を返す場合があります。The IsLeapYear method may return a different result than it did previously.

PersianCalendar クラスの使用Using the PersianCalendar class

アプリケーションではPersianCalendar 、オブジェクトを使用して、ペルシャ暦で日付を計算したり、グレゴリオ暦の日付とグレゴリオ暦の日付を変換したりします。Applications use a PersianCalendar object to calculate dates in the Persian calendar or convert Persian dates to and from Gregorian dates.

オブジェクトをPersianCalendarカルチャの既定の暦として使用することはできません。You cannot use a PersianCalendar object as the default calendar for a culture. 既定の暦はCultureInfo.Calendarプロパティによって指定され、 CultureInfo.OptionalCalendarsプロパティによって返されるいずれかの暦である必要があります。The default calendar is specified by the CultureInfo.Calendar property and must be one of the calendars returned by the CultureInfo.OptionalCalendars property. 現在、 PersianCalendarクラスは、 CultureInfoクラスでサポートされているカルチャのオプションの暦ではないため、既定の暦にすることはできません。Currently, the PersianCalendar class is not an optional calendar for any culture supported by the CultureInfo class and consequently cannot be a default calendar.
