Age Calculator

Calculate exact calendar age between a birth date and any target date.

This Age Calculator shows the precise difference between two dates in years, months, and days. It also provides total months, total weeks, total days, and the next birthday with a simple countdown. It is useful for forms, HR workflows, eligibility checks, school admissions, planning milestones, and general date-of-birth questions.

Instead of giving only a rough day count, the tool applies calendar logic so the age breakdown is easier to understand and use. You can also attach a name or label to generate a more readable summary sentence for the result panel.
