If there's not a folder for the month, create one.

Conversely, you can just right-click it, rename it, and use it. 

When you create a new item in Sitecore, never use spaces in the item name. Spaces make the Internet weep. Also, don't run words together to create something not found in the dictionary. Instead, use words that are separated by dashes. This helps search engines find your content.

Once the page is created, fill in the parts.

Approve the news item you created.

Select the month folder that contains the news item.

Click the small arrow to the right of the publish button. Choose "Publish item."

Make sure "Publish subitems" is checked, and click the publish button.
