Our age calculator is extremely accurate. It takes into account leap years, different month lengths, and can even calculate to the minute if you provide your birth time. The calculations are based on standard calendar rules and mathematical principles for determining time intervals.

This is because we calculate the exact number of months between your birth date and today, accounting for the varying lengths of months. It's a more accurate representation than simply multiplying years by 12. For example, if you were born on January 15 and today is February 10, you're 0 years and 0 months old in our precise calculation, not 0 years and 1 month.

No, all calculations are performed in your browser. We do not store your birthdate or any other personal information on our servers. Your privacy is important to us, and our age calculator is designed to work without collecting any personal data.

Yes, you can calculate anyone's age by entering their birth date. The calculator works the same way regardless of whose birth date you enter. This is useful for parents tracking their children's ages, genealogy research, or any other situation where you need to know someone's precise age.

Entering the birth time is optional but allows for more precise calculations down to the hour and minute. This can be particularly useful for very young infants where hours and minutes matter more, or for highly precise age calculations for legal or official purposes.

Our calculator automatically accounts for leap years in its calculations. A leap year occurs every 4 years (with some exceptions) and adds an extra day (February 29) to the calendar. The calculator correctly adds this extra day when calculating the total number of days between dates that span leap years.

Yes, our age calculator is fully responsive and works on all devices including smartphones, tablets, laptops, and desktop computers. The interface automatically adjusts to provide the best experience based on your screen size.

Yes, our calculator can handle dates from any era, including dates before 1900. However, please note that very old dates may be subject to calendar system changes (like the switch from Julian to Gregorian calendar) which could affect the absolute precision of the calculation.

Our standard age calculator calculates age based on the current date. However, we're working on a feature to allow calculation between any two dates, including future dates, which will be available soon.

No, you can perform as many calculations as you want. Our service is completely free and unlimited. Since all calculations are performed in your browser, there's no limit on the server side.
