We analyzed 14 million Facebook posts to pinpoint the best time to post on Facebook, the best day to post on Facebook, and which days and times are best avoided.

Every few years, someone declares that Facebook is dead. And then 3 billion people log in anyway.

When it comes to social media platforms, Facebook is as crowded as they come. The social network currently has 3 billion active users — so almost a third of the world's population has a Facebook account they use regularly.

Crowded as it may be, it's still a powerful social media marketing platform for businesses and creators — it’s why I’ve recently added Facebook into my social media crossposting strategy.

I already have some Instagram content that I think will resonate on Facebook, and I’m experimenting with crossposting it there. With all that solid content locked and loaded, one of the first things I defined in my shiny new Facebook social media strategy was when to post for maximum engagement.

When it comes to the Facebook algorithm, engagement — reactions, comments, shares, and likes — is a strong signal that your content is valuable and that more people will enjoy having it in their Facebook news feeds.

The higher your engagement, the higher your reach tends to be — and the greater your chance of achieving your social media goals, whether that means driving traffic to your website, making a sale, or simply growing your Facebook following.

So, how do you pinpoint the best time to post on Facebook for your audience, especially if you're just starting out (or you’ve dusted off an old Facebook account, like me)?

The first place I looked was our data.

The Buffer data team has analyzed the performance of more than 14 million Facebook posts sent via Buffer by businesses, creators, and influencers to pinpoint the best time to post on Facebook, the best day to post on Facebook, and which days and times are best avoided.

Key takeaways

• Peak posting time: The single best time to post is Thursday at 9 a.m., with Wednesday and Sunday mornings also delivering strong engagement.
• Best day: Wednesday is the top-performing day for Facebook engagement overall, with Thursday and Tuesday following close behind.
• Morning advantage: Engagement peaks during morning hours (6 a.m. – 11 a.m.) on weekdays, with afternoons (12 p.m. – 5 p.m.) consistently showing the lowest engagement across most days.
• Avoid the weekend: Saturday is the worst day to post on Facebook, with engagement dropping significantly compared to mid-week — Sunday performs slightly better but still trails weekdays.
