Yes but it will be displayed in a different location depending on your scheduled publication date.
The editorial calendar of Nelio Content shows all the posts that have a publication date set. If you create a new post and set a publication date for it, this post will appear in the calendar.

But if you have not set a publication date, then you will only see the post in the Unscheduled posts section to the right of the editorial calendar.

Notice that at the top of the calendar, you have an icon that shows a small calendar. By clicking on it, you can display the calendar showing only those posts that have a date assigned to them or also showing those posts that do not yet have a publication date.
Schedule Publication Date
To schedule a post with a publication date, you can do it directly in the editorial calendar or in the edition of the post itself.
From the editorial calendar, simply select with the mouse and drag the unscheduled post to the date you want it to be published and drop it (note that it should be a future date). It will automatically have a scheduled date of publication.

Alternatively, if you edit the post, simply click on the Immediate link to the right of Publish in the Status and Visibility section of the document editor. You will be able to select the date of publication and schedule it.

Once you do that, you’ll see the post as scheduled in the editorial calendar of Nelio Content. Note that the calendar is completely synced with the WordPress post editor.
