Ramadan
/ˈræmədæn/(亦作Ramadhan)
noun
- the ninth month of the Muslim year, during which strict fasting is observed from sunrise to sunset回历9月（月内教徒每日从黎明到日落禁食）, 斋月, 莱麦丹（月）。
词源
from Arabic ramadān, from ramada 'be hot'. The lunar reckoning of the Muslim calendar brings the fast eleven days earlier each year, eventually causing Ramadan to occur in any season; originally it was supposed to be in one of the hot months.
