请帮忙看看这个计算24节气的程序吧。。。

[weixin_38054592]

代码：

public static string ChineseTwentyFourDay(DateTime date1)
{
string[] SolarTerm = new string[] { "小寒", "大寒", "立春", "雨水", "惊蛰", "春分", "清明", "谷雨", "立夏", "小满", "芒种", "夏至", "小暑", "大暑", "立秋", "处暑", "白露", "秋分", "寒露", "霜降", "立冬", "小雪", "大雪", "冬至" };
int[] sTermInfo = new int[] { 0, 21208, 42467, 63836, 85337, 107014, 128867, 150921, 173149, 195551, 218072, 240693, 263343, 285989, 308563, 331033, 353350, 375494, 397447, 419210, 440795, 462224, 483532, 504758 };
DateTime baseDateAndTime = new DateTime(1900, 1, 6, 2, 5, 0); //#1/6/1900 2:05:00 AM#
DateTime newDate;
double num;
int y;
string tempStr = "";
y = date1.Year;
for (int i = 1; i <= 24; i++)
{
num = 525948.76
* (y - 1900) + sTermInfo[i - 1];
newDate = baseDateAndTime.AddMinutes(num);//按分钟计算
if (newDate.DayOfYear < date1.DayOfYear)
{
//tempStr = SolarTerm[i - 1];
tempStr = string.Format("{0}[{1}]", SolarTerm[i - 1], newDate.ToString("yyyy-MM-dd"));
Console.WriteLine(tempStr);
//break;
}
}
return tempStr;
}


我这里用Console输出所有节气（参数“date1”之前的所有节气），我对比了一下，发现有一个是错误的，就是“大暑”，baidu上查到是7-22，但是这个程序计算是7-23
感觉这个程序不太靠谱，请大家帮忙看看那里错了？
