In Japanese, the month is known as hachigatsu (Japanese: 八月) or traditionally hazuki (Japanese: 葉月).
The most common etymology is that it is a shortening of haochizuki (Japanese: 葉落月), meaning "month of falling leaves". Another explanation derives it from hoharizuki (穂張月), from 稲穂 (inaho, "ear of rice") + 張り (hari, "stretch; spread") + 月 (tsuki, "month").
Below is a list of the start and end dates of Bāyuè in the Gregorian calendar. Because the 1-hour difference between China and Japan/Korea occasionally affects the date on which a new moon occurs, the dates below can differ from those of the Japanese and Korean calendars.
