Frequently Asked Questions

Find answers to common questions about age calculation

How accurate is the age calculator?
Our age calculator is extremely accurate. It accounts for leap years, different month lengths, and even leap seconds in its calculations. The algorithm precisely calculates the difference between two dates down to the exact day.
Can I calculate my age as of a future date?
Yes, you can! Simply enter your date of birth and then select any future date in the "As of Date" field. The calculator will show how old you will be on that specific future date.
Why does the calculator show different results than other age calculators?
Different calculators may use slightly different algorithms. Our calculator provides the most precise calculation by accounting for the exact number of days in each month and leap years. Some calculators may use approximations (like 30 days per month) which can lead to slight variations.
Can I calculate someone else's age?
Absolutely! You can use this calculator to determine anyone's age. Just enter their date of birth and optionally a reference date to see how old they are or will be on that date.
Does the calculator work for historical dates?
Yes, the calculator works for any valid dates, including historical ones. You can calculate the age of historical figures or determine how old someone would be today if they were born centuries ago.
How does the calculator handle leap years?
Our calculator fully accounts for leap years in all calculations. It recognizes which years are leap years (divisible by 4, except for century years not divisible by 400) and adjusts the day count in February accordingly for precise age calculations.
