Can I calculate age as of a future or past date?

Yes. Set the reference date to any date you need instead of today — useful for eligibility checks on a specific deadline.

Does it account for leap years correctly?

Yes. The calculation is based on actual calendar dates, so leap years are handled correctly.

Why does my age show in years, months, and days?

Breaking the result into years, months, and days gives a more precise answer than years alone, which is useful for forms that need an exact age.
