The Best Time to Post on Facebook

Facebook timing advice is usually a list of hours with no word on which audience it assumed, which makes it impossible to adapt. This guide works out the best time to post on Facebook from the largest published timing study, from where Facebook's high-value audience lives, and from why Facebook's ranking forgives a mistimed post in a way Reddit never does. The American and British Facebook audiences are both awake for only about four good hours a day, and a free day-and-hour grid on this page shows every posting slot.

The quick answer: post Tuesday to Thursday, 12 to 3 PM US Eastern, which is 5 to 8 PM in Britain. That Tuesday to Thursday midday window sits inside the highest-engagement band in the largest published Facebook timing study, and it is also the widest stretch when the American and British Facebook audiences are both awake.

Avoid posting to Facebook at the weekend. Saturday and Sunday are the lowest-engagement days of the week on Facebook, and Sunday has no reliable peak hour at all.

The day and hour grid in your own local time

Every cell in the grid is one hour of one day. A cell's colour is how much of your chosen Facebook audience is awake at that hour, multiplied by the day-of-week engagement pattern from Sprout Social's study, so the darkest cell is the best posting slot. The grid opens on the best slot for the American audience, on your clock, read from your browser's time zone. Pick "Optimise for both" to include the British audience as well. The grid never sends your time zone or your choices anywhere.

How this is calculated. Choosing "Optimise for both" scores each slot on whichever of America and Britain has the smaller share of its audience awake, so the grid never recommends an hour that is useless for one country. The grid's hourly curve is a typical waking and phone-checking pattern applied to each country's local time, not measured Facebook data, so treat the shape of the curve as reliable and its exact numbers as indicative. The grid already accounts for daylight saving.

Post Tuesday to Thursday, 12 to 3 PM US Eastern

Facebook engagement data and the waking hours of the American and British audiences both point at the same Facebook posting window.

Aiming a Facebook post at 1 PM US Eastern only helps if the post is finished in time, and the unfinished part is usually the post's picture, still on a phone. Camera to Clipboard, one of my own apps, is a phone camera that puts what it photographs straight onto your computer's clipboard.

Facebook is a slow burn, so the ranking forgives a late post

Facebook keeps showing a well-liked post for hours or days, and that slow ranking is why the best hour to post on Facebook is later in the day than the best hour to post on Reddit.

Reddit rewards you for posting when nobody else is posting. Facebook just rewards you for posting when everybody is online.

If your goal from Facebook is app installs, sales or leads rather than a big view count, how much each Facebook viewer is worth varies enormously by region.

America and Britain share only about four good hours a day

The five-hour time difference between US Eastern time and Britain sounds manageable until you compare the hours when each country's Facebook audience is awake, shown here in US Eastern time.

The American evening is an excellent time to post on Facebook if your audience is only American. Posting at midday US Eastern, rather than in the American evening, is the price of reaching the British audience too.

Use Repeat Recorder to rehearse the video you post at midday

Reaching both the American and British Facebook audiences leaves about four usable hours a day, so a post has to be made before those hours start. A short video of you talking is the post most likely to be unfinished in time, because the words get rewritten between takes. Repeat Recorder, another of my own apps, records you and plays each take straight back without you touching the phone.

Everyone misreads the largest timing study by ignoring local time

Most published Facebook timing tables trace back to the same handful of studies, and one detail of the biggest study, by Sprout Social, changes how you should apply its posting times.

Your industry moves the window by several hours

In Sprout Social's Facebook data, the best posting hours differ more between industries than between days of the week, so if your industry is listed here, its hours should beat the average for all of Facebook.

Reddit and Facebook need two opposite posting strategies

Copying your Reddit schedule onto Facebook, or the reverse, quietly costs you reach.

The first hour matters on Facebook, just less than on Reddit

Facebook forgiving a mistimed post is not the same as Facebook ignoring timing, because early engagement still decides how far a post travels.

Use Camera to Clipboard to answer a comment with a photo

Replying to comments inside the first hour keeps Facebook showing a post, and the reply that settles a commenter's question is often a picture sitting on your phone while the comment box is open on your computer. Camera to Clipboard, one of my own apps, gets that picture from the phone to the computer in one step.
