About Age Calculation
How Is Age Calculated?
Age is calculated by finding the difference between your date of birth and the current date (or a specified date). Our calculator accounts for varying month lengths and leap years to give you an exact result down to the day.
Age Counting Systems
Different cultures count age differently. In most Western countries, age starts at 0 at birth and increases on each birthday. In some East Asian cultures (Korean age system), a person is considered 1 year old at birth and gains a year on New Year's Day.
Leap Year Birthdays
If you were born on February 29th (a leap day), your birthday only occurs every 4 years. In non-leap years, people born on Feb 29 typically celebrate on either February 28th or March 1st.
Why Know Your Exact Age?
Knowing your exact age is useful for legal documents, medical records, insurance applications, retirement planning, and milestone celebrations. Our calculator provides precision down to the second.
