How can PHP developers avoid errors related to time adjustments when working with date calculations?

PHP developers can avoid errors related to time adjustments when working with date calculations by setting the default timezone in their PHP script. This ensures that all date and time functions use the correct timezone, preventing discrepancies in calculations. To set the default timezone, developers can use the `date_default_timezone_set()` function with the desired timezone as a parameter. 

// Set the default timezone to UTC
date_default_timezone_set('UTC');

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