推荐答案

您实际上并不需要构造一个日期时间范围内解决这个问题。基于每月用一个简单的如果返回的二星级标志之一就足够了每个月声明一个简单的switch语句。

You don't actually need to construct a datetime range to solve this. A simple switch statement based on the month with a simple if statement for each month that returns one of two star signs will suffice.

   e.g
     switch (month)
     {
       case 1:
          if (day <20) return "Capricorn"; else return "Aquarius";
          break;
       case 2:
          ...
