What are some potential pitfalls of using date calculations in PHP, as seen in the examples provided in the forum thread?

One potential pitfall of using date calculations in PHP is not taking into account timezones, which can lead to incorrect results or unexpected behavior. To solve this issue, it's important to always set the timezone before performing any date calculations to ensure consistency and accuracy. 

// Set the timezone to the desired value before performing any date calculations
date_default_timezone_set('America/New_York');

// Perform date calculations with the correct timezone set
$today = date('Y-m-d');
$nextWeek = date('Y-m-d', strtotime('+1 week'));
echo "Today: $today\n";
echo "Next week: $nextWeek\n";
