frequently asked questions about age difference
How accurate is the age difference calculator?
Our age difference calculator is 100% accurate. It accounts for leap years, different month lengths, and uses precise date mathematics to give exact results.
Does it handle negative differences?
Yes! The calculator always shows positive difference and indicates which date is earlier. The "older" information tells you which person is older.
Can I calculate difference in total days only?
Absolutely! The "total days" field shows the complete difference in days. You also get total weeks and total months for convenience.
What about February 29 in leap years?
Our calculator properly handles February 29. If you enter Feb 29 in a non-leap year, it automatically adjusts to Feb 28 for valid calculation.
