In terms of code maintenance and readability, what are the benefits of using comments and clear variable names in PHP scripts for date calculations?

Using comments and clear variable names in PHP scripts for date calculations improves code maintenance and readability by providing context and explanations for the logic behind the calculations. This makes it easier for other developers (or even yourself in the future) to understand the code and make changes if needed. Additionally, clear variable names help to convey the purpose of each variable, making the code more self-explanatory. 

// Calculate the next week's date
$currentDate = date('Y-m-d');
$nextWeekDate = date('Y-m-d', strtotime('+1 week', strtotime($currentDate)));

echo "Current Date: $currentDate\n";
echo "Next Week's Date: $nextWeekDate\n";
