Age Calculation Across Cultures
Western System
This calculator uses the most common system where age increases on a person’s birthday. For example, someone who has lived for 3 years and 11 months is considered 3 years old.
East Asian Counting
In some cultures, age is expressed by counting years including the current year. For example, a twenty-year-old is in their twenty-first year of life.
Chinese Traditional System
In one traditional Chinese system, people are born at age 1, and their age increases at the Traditional Chinese New Year rather than their birthday.
