万年历查询程序. C语言代码

万年历查询程序. C语言代码,第1张

除了天数差计算,基本上是完成了你所提出的功能(天数差计算其实已经提供了年内序数计算方方法,可以在此基础上完善即可)。包含星期计算、公历转农历、农历转公历、节气查询。数据与算法均为原创,绝非网上复制而来。附件中有源代码,同时附带农历数据提取工具,可提取1600到7000年之间的任意年份区间,提取后的数据为压缩数据,占用空间小,同时数据包含数九、三伏、入梅和出梅,非常适合写一份完整的万年历。

部分核心算法函数如下:

//判断闰年,参数:年份,返回值:0-平年,1-闰年

int IsLeapYear(int iYear)

//计算日期在年内的序数,参数:年,月,日,年内序数,返回值:0-失败,1-成功

int GetDaysNumInYear(int iYear, int iMonth, int iDay,int *nDays)

//从年内序数计算月、日,参数:年,年内序数,月,日,返回值:0-失败,1-成功

int GetDateFromDays(int iYear, int nDays, int *iMonth, int *iDay)

//检验年、月、日的合法性,参数:年,月,日,返回值:0-失败,1-成功

int DateCheck(int iYear,int iMonth,int iDay)

//获取农历新年的公历年内序数,参数:农历年,返回值:农历新年的公历年内序数

int LunarGetNewYearOrdinal(int iLunarYear)

//获取农历月的天数,参数:农历年,农历月,是否为闰月,返回值:该农历月的天数,为0代表参数无效

int LunarGetDaysofMonth(int iLunarYear,int iLunarMonth,int IsLeapMonth)

//展开大小月数据表(某一年的),参数:农历年,从上一年十一月开始到当前年份(闰)十二月的每月天数,返回值:0-失败,1-成功

int LunarExpandDX(int iLunarYear,int iDayOfMonth[15])

//获取农历某一年的闰月情况,参数:农历年,返回值,该年的闰月月份,0表示无闰月

int LunarGetLeapMonth(int iLunarYear)

//公历转农历,参数:公历年、月、日,农历年、月、日,是否为闰月,返回值:0-失败,1-成功

int Gongli2Nongli(int iYear,int iMonth,int iDay,int *iLunarYear,int *iLunarMonth,int *iLunarDay,int *iIsLeapMonth)

//农历转公历,参数:家历年、月、日,是否为闰月,公历年、月、日,返回值:0-失败,1-成功

int Nongli2Gongli(int iLunarYear,int iLunarMonth,int iLunarDay,int iIsLeapMonth,int *iYear,int *iMonth,int *iDay)

//得到指定年份的节气信息,首个是小寒

int GetJieQi(int iYear,int uMonth,unsigned int uJieQi[2])

//计算星期

unsigned int GetDayOfWeek(int iYear,int uMonth,int uDay)

用VB做万年历,非常关键点就是农历写法,参考代码如下:

#Region " 返回农历 "

'返回农历

'cCalendar.MaxSupportedDateTime 返回支持的最大日期,即2101-1-28

'cCalendar.MinSupportedDateTime 返回支持的最小日期,即190-2-19

Private cCalendar As New System.Globalization.ChineseLunisolarCalendar

Public Function PubFunGet_CNDate(ByVal sDateTime As Date) As String

Dim lmonth As Integer = cCalendar.GetMonth(sDateTime)

Dim lday As Integer = cCalendar.GetDayOfMonth(sDateTime)

Dim lweek As Integer = cCalendar.GetDayOfWeek(sDateTime)

'获取闰月, 0 则表示没有闰月

Dim leapMonth As Integer = cCalendar.GetLeapMonth(lyear)

Dim isleap As Boolean = False

If (leapMonth >0) Then

If (leapMonth = lmonth) Then

'闰月

isleap = True

lmonth = lmonth - 1

ElseIf (lmonth >leapMonth) Then

lmonth = lmonth - 1

End If

End If

End Function
