Age & generation calculator
Two calculators in one — work out an exact age between any two dates, or estimate how many generations span two birth years.
Pick both dates to see the age.
Batch — many date pairs at once
Drop a CSV or JSON file with `startDate` and `endDate` columns (YYYY-MM-DD). Each row's exact age is computed and shown below.
