Answer 1

You said "don't work". But, do you any any error message ?

To calculate the difference between two dates, you have to create a function. In your case a twig extension.

• http://symfony.com/doc/current/templating/twig_extension.html
• How can I create a symfony twig filter?

Of course, the function "time_diff" exist in the native support. See these topics:

• How to get days difference in twig

Install the correct libraries, and the twig extension to load this module.
