Common Questions About Age Calculation

How is age calculated precisely?

Our calculator uses the difference between dates while accounting for varying month lengths and leap years. It calculates years first, then months, and finally days to give you the most accurate representation of your age.

Why might my age differ from simple year subtraction?

Simple year subtraction doesn't account for whether your birthday has occurred yet in the current year. Our calculator considers the exact month and day to provide accurate results.

How does the calculator handle leap years?

The calculator automatically accounts for leap years (February 29) in its calculations, ensuring accurate results even for those born on leap days.

Remember: For important legal or official purposes, always verify age calculations with official documents. Our calculator provides accurate results but should be used as a reference tool.
