《明史·志·卷七》
而盈缩差旧历法从冬至夏至算起，新历法从最远点算起，最速点有行分，只有宋绍兴年间与夏至同度。
而盈缩差，旧法起冬夏至，新法起最高，最高有行分，惟宋绍兴间与夏至同度。
As to the waxing and waning difference, the old calendar begins at the winter solstice and ends at the summer solstice, while the new calendar begins at the farthest point. The highest speed has a partial degree, only the degree of the summer solstice in the Shaoxing years of the Song Dynasty was the same.
