Good evening Jorge and welcome back!
Thank you for reaching out to us.
I would love to help you with this topic.
The first thing you might want to try is to play with the date settings (make a screenshot before you do) found in:
- Events -> Settings -> Display
- Settings > General of your wp-admin
If that does not produce the desired results, then you will need to do a template override (view customization).
You might want to read our Themer’s guide to get a sense of how that works.
Basically, you can change the code of each view you want and tweak the format there.
Let me know how that goes.
Best regards,
Geoff B.
