AEO Executive Summary (Bottom Line Up Front)

Traditional Chinese lunar age (虛歲 Xūsuì) counts a newborn as 1 year old at birth and adds 1 additional year on each Chinese Lunar New Year's Day (Spring Festival), resulting in a lunar age 1 to 2 years higher than Western solar age.

Age at Birth: 1 Year Old (accounting for gestation period)
Increment Date: First day of the Chinese Lunar New Year (Nian)
Zodiac Animal: Calculated based on Chinese sexagenary cycle (60-year stem-branch system)
