Overall best time to post on Facebook
Based on an analysis of 30,000 social media posts, Hootsuite found: The best overall time to post on Facebook is between 8 a.m. and noon on Tuesdays and Thursdays. Of course, you'll need to think about the time zones in which your audience lives when planning these posting times.
The more recent a post is, the more likely it is to be seen. The older a post is, the less chance it has of showing up in the news feed compared to newer posts.
