推荐答案

您所描述的是天数，而不是日历系统。日计数是将两个日期之间的期间转换为年份分数的机制。

What you describe is a day count not a calendar system. A day count is a mechanism for converting the period between two dates into a year fraction.

OpenGamma OG- Commons包括多天计数的实现，包括30E / 360，这可能是您需要的方法。

OpenGamma OG-Commons includes implementations of many day counts, including 30E/360 which may be the method you need.
