The Vietnamese word "niên canh" refers to the concept of a "birth date" or more specifically, it is often used in relation to the year of birth in the context of the Vietnamese lunar calendar. It is a compound word where "niên" means "year" and "canh" can refer to the cycle of years in the lunar calendar.
While "niên canh" primarily refers to the birth year, in broader contexts, it can also imply the idea of an era or a significant period in someone's life, especially when discussing the influences of specific zodiac years on personality traits.
Understanding "niên canh" is important for grasping Vietnamese cultural elements, especially those related to astrology and personal identity.
