类型 Tiangan 和 Dizhi 分别表示天干和地支。
总体上来说其与五行类似，主要的不同之处在于其序数是具有一定意义的，因此提供了 Index 属性和 FromIndex 方法，且其值是从 1 开始的：
[2]:
var numbers = Enumerable.Range(1 - 2, 12 + 4);
var table = new ConsoleTable("i", "t = Tiangan.FromIndex(i)", "t.Index", "d = Dizhi.FromIndex(i)", "d.Index");
foreach (var i in numbers)
{
var t = Tiangan.FromIndex(i);
var newIT = t.Index;
var d = Dizhi.FromIndex(i);
var newID = d.Index;
var starT = newIT == i ? ' ' : '*';
var starD = newID == i ? ' ' : '*';
table.AddRow(i, $"{starT}{t:C} {t}", newIT, $"{starD}{d:C} {d}", newID);
}
table.Write(Format.Minimal);
| i | t = Tiangan.FromIndex(i) | t.Index | d = Dizhi.FromIndex(i) | d.Index |

不过，由于在使用 default 创建结构体时，其内部值会为零。因此，内部值不能使用上述操作的结果。考虑到这一问题，我们仍然提供了强制转换运算符，它直接使用内部值 Index - 1 ：
[3]:
var numbers = Enumerable.Range(0 - 2, 12 + 4);
var table = new ConsoleTable("i", "t = (Tiangan)i", "(int)t", "d = (Dizhi)i", "(int)d");
foreach (var i in numbers)
{
var t = (Tiangan)i;
var newIT = (int)t;
var d = (Dizhi)i;
var newID = (int)d;
var starT = newIT == i ? ' ' : '*';
var starD = newID == i ? ' ' : '*';
table.AddRow(i, $"{starT}{t:C} {t}", newIT, $"{starD}{d:C} {d}", newID);
}
table.Write(Format.Minimal);
| i | t = (Tiangan)i | (int)t | d = (Dizhi)i | (int)d |
