FAQ

How do I calculate my exact age?

Enter your date of birth and the 'as of' date. The tool computes full years, remaining months and remaining days, adjusting for month lengths and leap years.

Is my date of birth stored anywhere?

No. The calculation happens entirely in your browser — nothing is sent to any server.

Why do I need exact age in years, months and days?

Many government, exam and immigration forms ask for exact age, not just the year. This tool gives you the precise breakdown.
