Frequently asked questions
How is my exact age calculated?
Your age is calculated by subtracting your date of birth from today's date (or any target date you choose), giving you the exact number of years, months, and days.
Can I calculate my age on a specific past or future date?
Yes. Change the "Age At Date" field to any date and the calculator will show your exact age on that day.
How many days until my next birthday?
The calculator automatically shows the number of days remaining until your next birthday and the exact date it falls on.
Is my date of birth stored anywhere?
No. All calculations happen entirely in your browser. Your date of birth is never sent to any server.
