Does the calculation account for birthdays not yet reached this year?

Yes. The result only increments after the birthday has passed.

Can I calculate age for a future birth date?

No. The tool expects a past birth date and uses today as the reference point.

Does it account for time zones?

It uses your browser's local date, so the current day is based on your system time zone.
