Calculate age from a date of birth and a chosen reference date.
The Age Calculator works out age from a date of birth and a reference date. Use today's date or choose another date when you need an age at a particular point in time.
Make sure the date fields represent the intended day and month. The interface does not show a separate date-format switch, timezone selector, or date-difference mode.
Years, months, and elapsed time are different ways to describe an interval. Check the displayed units rather than assuming every result includes weeks, hours, minutes, or seconds. Do not treat a date-only calculation as an exact elapsed-time measurement.
The calculator can help with birthday planning, personal milestones, or a date check for a form. For legal eligibility or official paperwork, confirm the source date and the rules used by the responsible organization. A displayed age does not establish eligibility for a service or scheme.
