PHP - function easter_date is not callable

Question

A template caused my site to behave weird and only the header was loaded. I discovered that there are a few lines calling the function easter_date. If the function is getting called then my site breaks.

So the function does not seem to exist. So I added the line if (!is_callable('easter_date')) return false; and it actually returned false.

I am running on PHP 5.6.40. It says that easter_date is available in PHP 4, 5 and 7

Why does easter_date not exist?

Example Code:

    $easter_d = date("d", easter_date($datum[0]));
    $easter_m = date("m", easter_date($datum[0]));

Add a `\` before the function for it look in the global namespace. See if that solves it. — Script47

The function is part of the calendar extension, see its manual: php.net/manual/en/calendar.installation.php — deceze

Try the following:

Ensure you have installed the extension
Try and add a \ before the function to make it search the global namespace for the function
