Frequently Asked Questions
How accurate are your age calculators?
Our calculators are accurate down to the day level. They correctly handle leap years, varying month lengths, and all calendar irregularities. The accuracy depends on your device having the correct date and time settings.
What if I was born on February 29?
If you were born on leap day (February 29), our calculators treat February 28 as your birthday in non-leap years for calculation purposes. This ensures consistent age calculation regardless of whether the current year is a leap year.
Do you store my date of birth?
No. All calculations happen entirely in your web browser using JavaScript. Your date of birth never leaves your computer and we have no record of any dates you enter. See our Privacy Policy for complete details.
Can I use these calculators offline?
Yes! Once the page loads in your browser, all calculations happen locally on your device. You can use our calculators without an internet connection.
Which timezone do the calculators use?
Our calculators use your device's local timezone. This means "today's date" reflects your location, not a universal time standard. This approach ensures results are meaningful for your actual daily experience.
Why is my age calculation different from another website?
Different calculators may use different calculation methods or handle edge cases differently. Our calculators follow standard date arithmetic principles and have been thoroughly tested. If you find a discrepancy, it may be due to timezone differences or how leap years are handled.
Can I use these for legal purposes?
Our calculators are for informational purposes only and should not be relied upon for legal matters. For legal documents, insurance claims, or official purposes, consult with appropriate professionals.
Do you offer calculators in other languages?
Currently our calculators are available in English only. The date format adapts to your device's regional settings, and results display in a universally understandable format.
How do I report a calculation error?
While we've thoroughly tested our calculators, if you encounter results that seem incorrect, please contact us with the specific dates involved and what result you expected. We take accuracy seriously and will investigate promptly.
Why do you show ads on the site?
Ads help us keep these calculators free for everyone. We've designed the site to ensure ads don't interfere with calculator functionality while generating modest revenue to maintain the service.
Can I embed your calculators on my website?
Our calculators are not currently available for embedding. However, you're welcome to link to our site from yours.
What calendar system do you use?
We use the Gregorian calendar, which is the internationally accepted civil calendar system used by most of the world today. For historical dates before your region adopted the Gregorian calendar, there may be slight discrepancies.
Do you have a mobile app?
We don't have a dedicated mobile app, but our website is fully mobile-responsive and works perfectly on smartphones and tablets. Simply visit our site in your mobile browser.
How often is the site updated?
Our calculators use your device's current date automatically, so there's no need for updates to maintain accuracy. We periodically update the site design and add new features based on user feedback.
