What are the potential pitfalls of using the wrong data type for storing birthdates in PHP?

Using the wrong data type for storing birthdates in PHP can lead to issues with date calculations, formatting, and comparisons. It is recommended to store birthdates as a DATE type in a database or as a Unix timestamp in PHP to ensure accurate date manipulation and comparisons. 

// Storing birthdates as Unix timestamps
$birthdate = strtotime('1990-05-15');
echo date('Y-m-d', $birthdate); // Output: 1990-05-15
