Frequently Asked Questions
How is age calculated exactly?
Age is calculated by finding the difference between your date of birth and the current date (or specified date). The calculator provides exact age in years, months, and days, accounting for leap years and varying month lengths.
Can I calculate my age as of a past date?
Yes! You can enter any date in the 'Calculate Age As Of' field to find out how old you were on that specific date. This is useful for filling out forms or determining your age at a specific point in time.
Why does my age in months not equal years times 12?
The calculator shows your exact age including partial months. For example, if you're 25 years and 3 months old, the total months would be 303 (25 × 12 + 3), not just 300. This provides a more accurate age calculation.
Is my date of birth stored or sent anywhere?
No. This age calculator works entirely in your browser using JavaScript. Your date of birth is never sent to our servers or stored anywhere. All calculations happen locally on your device.
Can I use this to calculate someone else's age?
Absolutely! You can enter any date of birth to calculate the age of family members, friends, celebrities, or historical figures. You can also calculate age differences between two people.
When is my next birthday and what day will it be?
After calculating your age, the tool automatically shows your next birthday date, which day of the week it falls on, and a countdown showing exactly how many days, hours, and minutes until your birthday!
Does the calculator account for leap years?
Yes! The age calculator automatically accounts for leap years (February 29th) and varying month lengths to provide the most accurate age calculation possible.
