Frequently asked questions

How do I enter a birthday, and which dates are supported?

Use the calendar picker, or the separate day, month and year selectors. Supported birthdays run from 1900 through today, and the result is your exact age in years, months and days.

How are 29 February birthdays handled in non-leap years?

A 29 February birthday uses 28 February in non-leap years. Ages are worked out from calendar anniversaries and elapsed dates, not from a birth time.

Does my birthdate leave my device?

No. The page states that your birthdate stays in this browser, and no account is needed to use the calculator.

Is the zodiac information in the result factual?

No. The zodiac content is entertainment, not factual predictions. Treat the age in years, months and days as the factual part of the result.
