Calculate your age in traditional Asian lunar calendar systems. Discover your Chinese zodiac, lunar birthday, and how traditional age calculation differs from Western systems.
Different Asian cultures have slightly different age calculation methods
Each element appears twice in a 10-year cycle, creating 60-year cycles.
Traditional Asian age systems count you as 1 year old at birth and increase your age at New Year, not on your birthday. This means you're typically 1-2 years older in traditional systems.
Most Asian countries now use Western age for official purposes (legal documents, school, work), but traditional age is still used in some cultural contexts and celebrations.
The Chinese zodiac is a 12-year cycle where each year is represented by an animal. Your zodiac animal is determined by your birth year and is believed to influence your personality and destiny.
