Age Calculator
Calculate exact age in years, months, and days
About Age Calculation
Age calculation is the process of determining the elapsed time between a person's birth date and the current date (or another specified date). While it seems simple, accurate age calculation needs to account for varying month lengths, leap years, and other calendar complexities.
How Age is Calculated
This calculator uses the following approach to calculate age:
- Years are counted as complete years between the two dates
- Months are counted as complete months beyond the year count
- Days are counted as remaining days beyond the month count
- The calculation accounts for leap years and varying month lengths
For example, from January 15, 2000 to March 20, 2023, the age would be 23 years, 2 months, and 5 days.
Age Calculator Uses
- Calculate exact age for official documents and applications
- Determine eligibility for age-restricted services or benefits
- Plan birthday celebrations and anniversary events
- Track developmental milestones for children
- Calculate time between any two dates for project planning
