How Age Calculation Works
Our calculator uses precise date arithmetic to determine your exact age. Unlike simple year subtraction which can be inaccurate around birthdays, our tool accounts for:
- Varying month lengths (28-31 days)
- Leap years (including century year rules)
- Time zone differences
- Day count between two specific dates
The algorithm first calculates full years, then remaining months, and finally remaining days to provide the most accurate age breakdown possible.
