How do I schedule social posts for a certain date and time?

When creating social posts, navigate to the top of the editor and select when you would like the social post to be posted.

Click Marketing from the main navigation bar, and click Social. Select Create social post in the top right hand corner. 

In the social post editor, once you have created the social post content, click When on the right hand side. You can then select which day you would like to post on, as well as what time. HubSpot gives you options of random times, which will make the post look organic.
