Frequently Asked Questions
How is age calculated exactly?
We calculate complete years, then remaining months, then days. If born Feb 29 (leap year), we use Feb 28 for non-leap year calculations. All date math accounts for varying month lengths.
Can I calculate age for someone who passed away?
Yes! Enter birth date and use death date as "target date" to see exact age at passing. Useful for genealogy, legal matters, or memorial purposes.
Why does my age show differently than I thought?
You might be calculating "running age" (current year - birth year) vs actual completed years. Our tool shows completed years - you turn 30 after completing 30 full years.
Is this accurate for legal documents?
Yes, mathematically accurate. However, legal age determination may have specific rules in your jurisdiction. Always verify with official sources for legal purposes.
Can I calculate pet ages?
Yes, but pet "years" differ from human years. Dogs/cats age faster initially. Use our result as chronological age, then apply species-specific aging formulas for "human equivalent" age.
