Frequently Asked Questions
How do I calculate my exact age?
Enter your date of birth and the calculator instantly shows your age in years, months, and days as of today, plus your age expressed in total months, weeks, and days. The result updates automatically — there is no button to press.
Does the age calculator account for leap years?
Yes. The calculation counts real calendar days, so February 29 in leap years is included. This is why your total-days figure may differ slightly from a naive "years × 365" estimate.
Is my date of birth stored or sent anywhere?
Your date of birth is saved only in your own browser (localStorage) so the Age and Next Birthday calculators can pre-fill it next time. It is never sent to a server. Use the "Forget my data" button to remove it at any time.
How many days old am I?
The calculator shows the total number of days you have lived alongside your age in years. It counts every real calendar day since your birth, including leap days, so the figure is exact rather than an estimate.
How is my age in months calculated?
Your age is shown both as years, months and days and as a single total of completed months. For example, 2 years and 6 months also appears as 30 months.
Can I calculate someone else's age?
Yes. Enter any date of birth — your own or another person's — and the exact age for that date is shown instantly. Only your own browser can pre-fill a saved date.
