About Age Calculator
Age Calculator helps you turn a date of birth into a clear age result with years, months, days, and total days lived. It is useful when you need more detail than a rough year count, especially for forms, birthday planning, school records, or personal milestones.
The calculator focuses on calendar-based age, so leap years and different month lengths are handled more naturally than simple day division. You can use it for one quick date check or compare several birth dates while planning events, documents, or reminders.
