The calculator counts completed calendar months and the remaining days. Monthly anniversaries that fall beyond the final day of a month are adjusted to that month's last day.
A birth date of January 31 reaches one completed month on February 28 in a non-leap year. February 29 anniversaries are adjusted to February 28 in non-leap years.
Birth years from 1900 through the current year are supported. Future dates and invalid calendar dates are rejected. This calculation is informational and is not a legal age determination.
Your birth date is processed locally in your browser. The calculator does not send or store your birth date on an external server.
