Age Calculator
Calculate your exact age in years, months, and days.
How to Do It Manually
To calculate your age manually, subtract your birth date from today's date. Count the full years first, then remaining months, then remaining days.
- Write down today's date (year, month, day).
- Subtract your birth year from the current year to get a base number of years.
- If your birthday hasn't occurred yet this year, subtract 1 from that number.
- Count remaining months and days for a precise result.
