PersianCalendar
屬性

範例

下列範例會使用 DateTime.Now 屬性、DateTime 的函式和波斯曆的 ToDateTime(Int32, Int32, Int32, Int32, Int32, Int32, Int32) 方法,來具現化 DateTime 物件。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. 然後,它會在西曆和波斯曆中顯示這些日期。It then displays these dates in both the Gregorian and Persian calendars. 它也會顯示波斯曆的日期範圍。It also displays the date range of the Persian calendar.

備註

波斯曆適用于大多數國家/地區(波斯文),雖然某些地區使用不同的月份名稱。The Persian calendar is used in most countries/regions where Persian is spoken, although some regions use different month names. 波斯曆是伊朗和阿富汗的官方行事曆,而這是在哈薩克斯坦和塔吉克斯坦等地區的其中一個替代行事曆。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

如需在 .NET Framework 中使用 PersianCalendar 類別和其他行事曆類別的詳細資訊,請參閱使用行事For information about using the PersianCalendar class and the other calendar classes in the .NET Framework, see Working with Calendars.

波斯曆中的日期從 Hijra 的年份開始,其對應于622西元Dates in the Persian calendar start from the year of the Hijra, which corresponds to 622 C.E. 當 Muhammad (PBUH)從 Mecca 遷移至 Medina 時,這是一年。and is the year when Muhammad (PBUH) migrated from Mecca to Medina. 例如,西元2002年3月21日For example, the date March 21, 2002 C.E. 對應至1381年西元 Persico 中 Farvardeen 月份的第一天。corresponds to the first day of the month of Farvardeen in the year 1381 Anno Persico.

波斯曆是以日光年份為基礎,大約是365天的時間。The Persian calendar is based on a solar year and is approximately 365 days long. 一年會迴圈處理四個季節,而新一年會從南部半球的赤道,到從地球中央觀看的北半球。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. 新的年份會標示 Farvardeen 月份的第一天,也就是北半球中的第一天。The new year marks the first day of the month of Farvardeen, which is the first day of spring in the northern hemisphere.

在波斯曆的前六個月中,每個月份都有31天,接下來的五個月都有30天,而上個月在閏年中有29天的時間,以及一年的30天。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. 閏年是一種年份,除以33時,餘數為1、5、9、13、17、22、26或30。A leap year is a year that, when divided by 33, has a remainder of 1, 5, 9, 13, 17, 22, 26, or 30. 例如,1370年的年份是閏年,因為將它除以33會產生17的餘數。For example, the year 1370 is a leap year because dividing it by 33 yields a remainder of 17. 每33年週期大約有八個閏年。There are approximately eight leap years in every 33-year cycle.

PersianCalendar 類別和 .NET Framework 版本The PersianCalendar class and .NET Framework versions

.NET Framework 4.6.NET Framework 4.6開始,PersianCalendar 類別會使用回曆日光天文演算法,而不是見習演算法來計算日期。Starting 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. 這可讓 PersianCalendar 的執行與在伊朗和阿富汗中使用的波斯曆一致,這兩個國家/地區的波斯曆最廣泛使用。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. 若已安裝 .NET Framework 4.6.NET Framework 4.6,此變更會影響在 .NET Framework 4 或更新版本上執行的所有應用程式。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.

因已變更的演算法而產生的結果:As a result of the changed algorithm:

  • 在西曆中轉換1800和2123之間的日期時,這兩種演算法應該會傳回相同的結果。The two algorithms should return identical results when converting dates between 1800 and 2123 in the Gregorian calendar.

  • 這兩種演算法可能會在將日期轉換為1800之前,以及在西曆後的2123時傳回不同的結果。The two algorithms may return different results when converting dates before 1800 and after 2123 in the Gregorian calendar.

  • [MinSupportedDateTime] 屬性值已從西曆的0622年3月21日變更為西曆中的0622年3月22日。The MinSupportedDateTime property value has changed from March 21, 0622 in the Gregorian calendar to March 22, 0622 in the Gregorian calendar.

  • [MaxSupportedDateTime] 屬性值已從波斯歷年9378之第10個月的第10天變更為波斯曆的第 10 9378 個月第13天。The 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.

  • IsLeapYear 方法可能會傳回與先前不同的結果。The IsLeapYear method may return a different result than it did previously.

使用 PersianCalendar 類別Using the PersianCalendar class

應用程式會使用 PersianCalendar 物件來計算波斯曆中的日期,或將波斯用日期轉換成西曆日期。Applications use a PersianCalendar object to calculate dates in the Persian calendar or convert Persian dates to and from Gregorian dates.

您無法使用 PersianCalendar 物件做為文化特性的預設行事曆。You cannot use a PersianCalendar object as the default calendar for a culture. 預設行事曆是由 CultureInfo.Calendar 屬性指定,而且必須是 CultureInfo.OptionalCalendars 屬性所傳回的其中一個行事曆。The default calendar is specified by the CultureInfo.Calendar property and must be one of the calendars returned by the CultureInfo.OptionalCalendars property. 目前,PersianCalendar 類別不是 CultureInfo 類別支援的任何文化特性的選擇性行事曆,因此不能是預設行事曆。Currently, the PersianCalendar class is not an optional calendar for any culture supported by the CultureInfo class and consequently cannot be a default calendar.
