《宋书·志·卷十五》
鄱阳哀王在去年闰三月逝世，闰月安排在季节变换之时，那么一定是四月的时分，应该以今年四月末为祥祭。
鄱阳哀王去年闰三月薨，月次节物，则定是四月之分，应以今年四月末为祥。
The Prince of Poyang died in the intercalary third month last year. The intercalary month is scheduled at the time of the seasonal transition, so it must have been during the April period. The mourning end ceremony and the ritual sacrifice should be held at the end of April this year.
