Age Calculator is an informational date-calculation utility. The results are intended to help with ordinary age arithmetic and general planning.

Not Legal or Government Advice

Age definitions and cut-off rules can vary by law, jurisdiction, institution and purpose. A result from this website should not be treated as an official determination of legal age or eligibility.

Not Medical or Financial Advice

Age may be relevant to medical, insurance, pension or financial decisions, but this calculator does not provide professional advice in those fields. Use the appropriate professional or official source when the decision is consequential.

Leap-Day Convention

For calendar-age calculations, this site treats February 28 as the anniversary of a February 29 birth date in non-leap years. An authority may apply a different rule, so its rule should control for official purposes.

Exact Time of Birth

The calculator primarily works with dates, not the exact time and place of birth. Hour, minute and second totals are therefore convenience estimates from the selected date boundary rather than a certified measure of lifetime duration.
