Age Calculator
Find your exact age in years, months, and days.
How Age Is Calculated
This calculator finds the exact difference between your date of birth and a target date (today, by default), breaking the result down into complete years, remaining months, and remaining days. This gives a far more precise answer than simply subtracting birth years.
Why Calculate Age Precisely?
Exact age calculations are useful for eligibility checks (like age-restricted services), legal documents, immigration forms, and even curiosity about milestones. Using the "Calculate Age As Of" field, you can also find out how old you were, or will be, on any specific date — useful for planning future events.
Frequently Asked Questions
Can I calculate my age on a future date?
Yes, set the "Calculate Age As Of" field to any future date to see exactly how old you'll be on that day.
Does this account for leap years?
Yes, the calculation is based on real calendar dates, so leap years are handled automatically and accurately.
