How can PHP developers effectively troubleshoot and debug issues related to date calculations in their code?

When troubleshooting date calculation issues in PHP, developers can start by checking the format of the dates being used, ensuring they are in a compatible format. They can also use built-in PHP functions like strtotime() and date() to manipulate and format dates accurately. Additionally, debugging tools like var_dump() or print_r() can help inspect variables and identify any inconsistencies in date calculations. 

// Example code snippet to troubleshoot date calculation issues
$date1 = '2022-01-10';
$date2 = '2022-01-15';

// Convert dates to timestamps for calculation
$timestamp1 = strtotime($date1);
$timestamp2 = strtotime($date2);

// Calculate the difference in days
$days_difference = ($timestamp2 - $timestamp1) / (60 * 60 * 24);

echo "The difference between $date1 and $date2 is $days_difference days.";
