How it Works: Formula & Examples
The **Age Calculator** determines the difference in time between two specified dates. It calculates your age in years, months, and days based on your birth date and the current date.
The core logic involves:
- Subtracting the birth year from the current year.
- Adjusting months and days to account for exact differences, borrowing from higher units (years, months) as needed.
Example:
If your birth date is October 26, 1990, and today is August 16, 2025:
- Years: $2025 - 1990 = 35$ years
- Months: August (7) is before October (9), so we borrow a year. $7 + 12 - 9 = 10$ months. Years become $34$. (Note: Months are 0-indexed in JS Dates).
- Days: 16 is before 26, so we borrow a month from August (31 days). $16 + 31 - 26 = 21$ days. Months become $9$.
So, your age would be 34 years, 9 months, and 21 days.
