efoula on "Event Start Date (Custom Metabox)"

Hello there,

Shortly, I have created a custom Post_Type called (event), with a custom meta-box called (event_starttextdate) by using the CMB Source Code.
And I have set the archive option to true in the custom Post_Type (event).

Now, all I want to do is the following:

1- wp_get_archives('type=monthly');
Want to get the archive months' links from the custom meta-box I have created (event_starttextdate) which is the start date of the event.

2- Custom Archive page for the custom Post_Type (event)
Want to build a simple archive template for the event post_type, to load the events for each month (when user click on the result month of the wp_get_archives('type=monthly'); ).

Your help is appreciated.

Thank you.
Best,
EF.
