1. What is Korean Age?

Korean age is a traditional age-counting method used in Korea where everyone gains one year at New Year's Day (January 1st) rather than on their birthday. This calculator provides the mathematical method often used to approximate Korean age.

2. How Does the Calculator Work?

The calculator uses the following formula:

Where:

• \( \text{Current Date} \) — Today's date or any reference date
• \( \text{Birth Date} \) — The person's date of birth
• 365.25 — Accounts for leap years (average days per year)
• +1 — The Korean age increment

Explanation: This calculates the difference in days between two dates, converts to years, and adds 1 according to Korean age counting.

3. Importance of Korean Age

Details: Korean age is significant in social interactions, determining formality levels, and is traditionally used in many aspects of Korean culture.

4. Using the Calculator

Tips: Enter your birth date and the current date (defaults to today). The calculator will compute your Korean age based on the mathematical approximation.

5. Frequently Asked Questions (FAQ)

Q1: Is this the official Korean age calculation?
A: This is a mathematical approximation. Official Korean age adds 1 year at birth and another year each January 1st.

Q2: Why does Korean age differ from international age?
A: Korean age counts the time in the womb as the first year, and everyone ages simultaneously on New Year's Day.

Q3: When is Korean age used?
A: Traditionally in social settings, though official documents now typically use international age.

Q4: What's the maximum difference between Korean and international age?
A: Up to 2 years - if born on December 31st, you'd be 1 year old at birth, then 2 years old the next day.

Q5: Is Korea changing this system?
A: As of 2023, South Korea officially uses international age for legal and administrative purposes, but traditional age remains in social contexts.
