Korean Age System
Korea traditionally uses a unique age-counting system where:

While South Korea is transitioning to international age standards, the traditional system remains influential in social contexts.

As our world becomes increasingly interconnected, understanding these global variations helps us appreciate both our differences and our shared human experiences across the lifespan.
Whether you’re planning international travel, working with diverse populations, or simply curious about global traditions, recognizing these important age milestones enhances our understanding of the rich tapestry of human culture and legal systems worldwide.
