Frequently asked questions
How is age calculated?
Age is calculated by finding the difference between your date of birth and today's date, expressed in complete years, months, and days.
Does this account for leap years?
Yes. The calculator uses real calendar dates, so leap years and varying month lengths are handled automatically.
Can I calculate age as of a future or past date?
This calculator compares your date of birth to today's date. For a different reference date, adjust your system clock or check back when planning ahead.
Is my date of birth stored anywhere?
No. All calculations happen locally in your browser. Nothing is sent to a server or stored.
