Hello Guillermo,

Both the home and blog page displays the newest posts in chronological order. Something must be messed up with the configuration. It could be a plugin or a setting.

If you want to change the way the theme displays posts by default, you could create a Page Template, write a custom query to load events in desired way, assign that template to one of your pages.

Unfortunately, we do not provide customization services. If you are not sure how to do it by your own, we recommend WP Kraken.

Please let me know if you have any questions.
