Blog post would be a custom calendar entry - you would need to create a custom calendar entry in the admin for blog posts first, and then you can add that custom entry to your calendar. See here for some more info:
Create custom entry types - Create Custom Entry Types - Marketo Docs - Product Documentation
Add custom entries directly to calendar - Create Entries Directly in the Marketing Calendar - Marketo Docs - Product Documentation
Thank you so much for your help!
