About Age Calculation
This calculator provides your exact age by calculating the difference between two dates. It accounts for varying month lengths and leap years to give you precise results.
How Age is Calculated
- Years: Complete years lived since birth
- Months: Additional months after the last complete year
- Days: Remaining days after the last complete month
- Total Days: Exact number of days between the two dates
Leap Years
A leap year occurs every 4 years (with exceptions for century years). Leap years have 366 days instead of 365, with February having 29 days. This calculator automatically accounts for leap years in its calculations.
Common Uses
- Calculate exact age for documents and forms
- Determine age difference between two people
- Calculate project or event duration
- Track milestones and anniversaries
Note: This calculator provides exact age calculations based on the Gregorian calendar. Results are accurate for dates after the calendar's adoption. The calculator accounts for leap years and varying month lengths.
