What is the issue with calculating events in a calendar based on dates in PHP?

The issue with calculating events in a calendar based on dates in PHP is that dates are not always consistent due to factors like leap years and daylight saving time. To solve this issue, we can use PHP's DateTime class which handles date and time calculations accurately, taking into account factors like timezones and daylight saving time. 

// Create DateTime objects for start and end dates
$startDate = new DateTime('2022-01-01');
$endDate = new DateTime('2022-12-31');

// Calculate the number of days between the two dates
$interval = $startDate->diff($endDate);
$numDays = $interval->days;

echo "Number of days between $startDate and $endDate: $numDays";
