What is the purpose of using DateTime objects in PHP for date calculations?

When working with dates and performing calculations in PHP, using DateTime objects can simplify the process and provide more accurate results. DateTime objects allow for easy manipulation of dates, such as adding or subtracting days, months, or years, as well as comparing dates. They also handle time zones and daylight saving time automatically, which can be tricky to manage manually. 

// Example of using DateTime objects for date calculations
$startDate = new DateTime('2022-01-01');
$endDate = new DateTime('2022-01-31');

// Calculate the difference in days between two dates
$interval = $startDate->diff($endDate);
echo $interval->days; // Output: 30
