What are the potential pitfalls of using the date() function in PHP for calculating dates?

One potential pitfall of using the date() function in PHP for calculating dates is that it relies on the server's timezone settings, which may not always be accurate or consistent. To ensure accurate date calculations, it is recommended to use the DateTime class in PHP, which allows for more flexibility and control over timezones. 

// Using the DateTime class to calculate dates
$timezone = new DateTimeZone('America/New_York');
$date = new DateTime('now', $timezone);
$date->modify('+1 day');
echo $date->format('Y-m-d');
