Drupal 7. How to fix date in email notification (newbie)?

Question

Drupal

Hello! I understand that, as usual, everything lies in some tiny little thing .... but I have already killed 2 days! Changed the date format everywhere, even in the view. But the date continues to come to the mail in the format 2018. 01.30 19:00, but you need, for example, Tue. Tell me, you can go crazy. Sending goes to mail and via SMS, using the type of materials and the created rule. If it is in the database, then where exactly to climb, step by step ... as for a teapot =) I cleared the cache ...
