Frequently Asked Questions

How is age calculated?

Age is calculated by subtracting your birth date from the target date (today or a specific date). The calculator accounts for leap years and varying month lengths for precise results.

Can I calculate age at a specific date?

Yes! Enter any date in the "Calculate Age At" field to see how old you were or will be on that date. This is useful for legal documents, retirement planning, or historical records.

Why does my age show differently in different calculators?

Some calculators use approximations (like 365.25 days per year), but we calculate exact years, months, and days by accounting for the actual calendar dates. This gives you the most accurate result.

What are "total months" and "total days"?

Total months/days show your age expressed entirely in one unit. For example, if you're 25 years old, that's approximately 300 months or 9,125 days. This is useful for certain calculations or legal requirements.
