About Our Age Calculator
Understanding how we calculate your age with precision and accuracy
How Age Calculation Works
The age of a person is calculated differently across various cultures. Our calculator uses the most common age system where age increases on a person's birthday.
- If you're 3 years and 11 months old, your age is displayed as 3 years
- Your age will increase to 4 on your next birthday one month later
Cultural Differences
In some Asian cultures, age is counted differently:
- In traditional Chinese systems, people are born at age 1
- Age increases at the Chinese New Year rather than birthdays
- A baby born just before New Year would be considered 2 years old days after birth
Month Calculation Notes
Our calculator handles month calculations in a straightforward way:
Standard Months
Feb 20 to Mar 20 is counted as exactly one month regardless of leap years
Month End Transitions
For dates like Feb 28 to Mar 31, we count Feb 28 to Mar 28 as one month plus 3 days
