Are there any common pitfalls to be aware of when working with date formats in PHP?

One common pitfall when working with date formats in PHP is not specifying the correct format when parsing or formatting dates. To avoid this issue, always use the correct format characters (e.g., Y for year, m for month, d for day) when working with dates in PHP.

// Example of parsing a date with a specific format
$dateString = '2022-01-15';
$date = DateTime::createFromFormat('Y-m-d', $dateString);
echo $date->format('Y-m-d'); // Output: 2022-01-15
