Note 1 — Chapter XI
Henry Yule translation
There are thirteen months to the Chinese year in seven out of every nineteen.
[“This interval of 10 years comprises 235 lunar months, generally 125 long months of 30 days, 110 short months of 29 days, (but sometimes 124 long and 111 short months), and 7 intercalary months. The year of twelve months is called a common year, that of thirteen months, an intercalary year.” (P. Hoang, Chinese Calendar, p. 12.—H. C.)]
