How to Use the Age Calculator

Our Age Calculator is a versatile tool that does more than just calculate your age. It provides comprehensive information about your birth date, including international age, Korean age, zodiac sign, and Chinese zodiac animal. This guide will walk you through all its features.

Getting Started

Step 1: Enter Your Birth Date

When you open the Age Calculator, you’ll see a date input field. You can enter your birth date in two ways:

  1. Click the calendar icon to select a date from the date picker
  2. Type directly into the field (format depends on your browser settings)

Step 2: View Your Results

Once you enter your birth date, the calculator instantly displays:

  • International Age (만 나이): Your age calculated from your birthday, which is the global standard
  • Korean Age (한국 나이): Your age according to traditional Korean counting
  • Days Until Birthday: How many days until your next birthday
  • Zodiac Sign: Your Western astrological sign based on your birth date
  • Chinese Zodiac Animal: Your animal sign based on your birth year

Understanding the Results

International Age vs Korean Age

The calculator shows both age systems side by side for easy comparison:

System Calculation Method
International Age Counts from 0, adds 1 each birthday
Korean Age Starts at 1, adds 1 every January 1st

For example, if you were born on July 15, 1995:

  • International age in 2026 (before July 15): 30 years old
  • Korean age in 2026: 32 years old

Chinese Zodiac Animals

The Chinese zodiac assigns an animal to each year in a 12-year cycle:

🐀 Rat → 🐂 Ox → 🐅 Tiger → 🐇 Rabbit → 🐉 Dragon → 🐍 Snake → 🐴 Horse → 🐐 Goat → 🐒 Monkey → 🐓 Rooster → 🐕 Dog → 🐖 Pig

Your animal is determined by the year you were born. In Korean culture, this is called “띠” (tti) and plays an important role in compatibility and fortune-telling.
