Your birth date is processed in your browser
All calculations (ages, Hijri conversion, date differences) run locally in your browser. The dates you enter are not sent to any server, not written to server logs, and never placed in the page URL.
What is stored on your device
We use your browser’s local storage for two things only:
- Your preferences: theme, digit style and time zone.
- Your birth date, only if you tick “Remember my birth date on this device”. It is deleted as soon as you untick the option or press Clear, and you can also remove it by clearing site data in your browser.
This data never leaves your device and we cannot access it.
Cookies
This site uses no cookies.
Analytics
If analytics are enabled, they will be cookieless and limited to generic events such as “age calculator used” or “print clicked”, with the calendar type. No dates are ever sent; the code rejects any value that looks like a date.
Sharing
“Copy result”, “Share” and “Share image” create the text or image on your device. Your birth date is included only if you explicitly choose to, and you decide who to share it with.
Advertising
The site does not show ads today. If ads are added, this page will be updated first to explain what ad providers collect; your birth date will remain outside any advertising system.
Contact
If you email us, we use your address only to reply.

The date of the last update is shown at the bottom of this page.
