What are some potential pitfalls or challenges when implementing dynamic content changes in PHP based on date conditions?

One potential pitfall when implementing dynamic content changes in PHP based on date conditions is ensuring that the date comparisons are accurate and handle time zones correctly. To avoid issues with time zone conversions, it's recommended to set the default time zone at the beginning of your script. Additionally, be mindful of how date formats are used to prevent unexpected behavior. 

// Set the default time zone to ensure accurate date comparisons
date_default_timezone_set('America/New_York');

// Get the current date
$currentDate = date('Y-m-d');

// Define the start and end dates for content changes
$startDate = '2022-01-01';
$endDate = '2022-01-31';

// Check if the current date is within the specified range
if ($currentDate >= $startDate && $currentDate <= $endDate) {
    // Display dynamic content based on date conditions
    echo 'Special promotion for January!';
} else {
    // Display default content
    echo 'Regular content';
}
