C # convert the Gregorian calendar to the lunar calendar

In. system. globalization. chineseLunisolarCalendar is a calendar class for China. It is used to calculate information about the calendar, such as the calendar and calendar year of the traditional Chinese calendar.

Use

static ChineseLunisolarCalendar cCalendar = new ChineseLunisolarCalendar();

CCalendar. MaxSupportedDateTime returns the supported maximum date, that is, 2101-1-28

CCalendar. MinSupportedDateTime returns the supported minimum date, that is

Next we will convert the Gregorian calendar to the lunar calendar.

/// <Summary> /// obtain the lunar date based on the Gregorian calendar /// </summary> /// <param name = "datetime"> Gregorian date </param> // /<returns> </returns> public static string GetChineseDateTime (DateTime datetime) {int lyear = cCalendar. getYear (datetime); int lmonth = cCalendar. getMonth (datetime); int lday = cCalendar. getDayOfMonth (datetime); // get the leap month. If the value is 0, the leapMonth int leapMonth = cCalendar is not displayed. getLeapMonth (lyear); bool isleap = false; if (leapMonth> 0) {I F (leapMonth = lmonth) {// leap = true; lmonth --;} else if (lmonth> leapMonth) {lmonth --;} return string. concat (GetLunisolarYear (lyear), "year", isleap? "Interval": string. Empty, GetLunisolarMonth (lmonth), "month", GetLunisolarDay (lday ));
}

Test results:

Input Date: 2010-3-4

Return to lunar calendar: Geng Yin, September 1, lunar January 19

It can meet simple requirements.

Other code is also attached:

# Region agricultural calendar year // <summary> // ten-day dry // </summary> private static string [] tiangan = {"A", "B ", "C", "ding", "E", "Ji", "Geng", "Xin", "Yi", "Xi "}; /// <summary> /// 12th branch // </summary> private static string [] dizhi = {"sub", "ugly", "", "Mao", "Chen", "Si", "Wu", "wei", "shen", "", "Wu", "Hai "}; /// <summary> /// Zodiac /// </summary> private static string [] shengxiao = {"rat", "Ox", "Tiger ", "free", "dragon", "snake", "horse", "goat", "monkey", "chicken", "dog", "Swine "}; /// < Summary> /// return the year of the calendar month. // </summary> // <param name = "year"> calendar year </param> // <returns> </returns> public static string GetLunisolarYear (int year) {if (year> 3) {int tgIndex = (year-4) % 10; int dzIndex = (year-4) % 12; return string. concat (tiangan [tgIndex], dizhi [dzIndex], "[", shengxiao [dzIndex], "]");} throw new ArgumentOutOfRangeException ("invalid year!

There is also a code to get the Zodiac by date:

/// <Summary> /// returns the Chinese zodiac // </summary> /// <param name = "datetime"> calendar date </param> /// <returns> </returns> public static string GetShengXiao (DateTime datetime) {return shengxiao [cCalendar. getTerrestrialBranch (cCalendar. getSexagenaryYear (datetime)-1];}
