Explanation: The calculation accounts for varying month lengths and leap years to provide an accurate result in years, months, and days.
Details: Precise age calculation is essential for medical dosing, educational enrollment, legal requirements, retirement planning, and various statistical analyses.
Tips: Enter the birth date and current date in the format YYYY-MM-DD. The current date defaults to today's date but can be modified for historical or future calculations.
Q1: How does the calculator handle leap years?
A: The calculation automatically accounts for leap years and varying month lengths to provide accurate results.
Q2: Can I calculate age for future dates?
A: Yes, by entering a future date as the current date, though this would represent projected age at that future date.
Q3: What's the most accurate way to calculate age?
A: Using exact dates (day, month, year) provides the most precise age calculation compared to using only years.
Q4: How is age different from duration?
A: Age specifically refers to the time elapsed since birth, while duration can measure any time interval between two dates.
Q5: Why might age calculation be important medically?
A: Many medical treatments, drug dosages, and screening recommendations are age-dependent, making accurate calculation crucial.
