What are the potential pitfalls of using a fixed year like 1970 for date calculations in PHP?

Using a fixed year like 1970 for date calculations in PHP can lead to incorrect results, especially when dealing with leap years or date ranges outside of that year. To avoid this issue, it's recommended to use the current year or a dynamic way to determine the year in your date calculations. 

// Get the current year for date calculations
$currentYear = date('Y');

// Use the current year in your date calculations
$date = date_create("$currentYear-01-01");
echo date_format($date, 'Y-m-d');
