To validate data dates, ensure that they follow the expected format (e.g., YYYY-MM-DD). Use programming libraries like Python's `datetime` or JavaScript's `Date` object to parse and check for errors. Implement rules for range validation to ensure dates fall within a logical timeframe, such as birth dates being in the past. Also, consider edge cases like leap years.
