The Best Time to Post on Facebook

Facebook timing advice is usually a list of hours with no explanation of which audience it assumed, which makes it impossible to adapt. This guide derives the answer instead: what the largest published timing study actually measured, where Facebook's high-value audience lives, why Facebook's ranking forgives a mistimed post in a way Reddit never does, and the awkward fact that America and Britain only overlap for about four good hours a day. There is a free day-and-hour grid below so you can see any slot, and a plain recommendation at the end.

Start here: the day and hour grid, which converts every posting slot into your own local time and shows who is awake around the world

Every cell is one hour of one day. Colour is how much of your chosen audience is awake at that hour, multiplied by the day-of-week engagement pattern from the Sprout study, so the darkest cell is always the best cell for whatever you picked. The grid reads your time zone from your browser and opens on the best slot for the American audience, on your clock. Switch the radio to "optimise for both" to recolour it for the hours that keep Britain in the room as well. Click any cell for the full readout. Everything runs in your browser and nothing is sent anywhere.

The short answer: Tuesday to Thursday, 12 to 3 PM US Eastern, which is the British evening and the American lunch hour at the same time

Two independent lines of evidence point at the same window, which is why this recommendation is more confident than the equivalent one for Reddit.

• The engagement data says midweek middays. Sprout Social's analysis of nearly two billion engagements across roughly 307,000 social profiles, measured between late November 2025 and late February 2026, found Monday to Thursday consistently strongest, with Tuesday and Wednesday running hot from midday through to 8 in the evening in each user's local time.
• The geography says the same thing. Midday US Eastern is the only stretch of the day when roughly three quarters of the American audience and four fifths of the British audience are awake simultaneously. Nothing else comes close on both counts.
• 1 PM Eastern is the single best hour if you want one number to schedule against. Around 78% of the American audience and 88% of the British audience are active at that moment.
• The weekend is the clear loser. Saturday and Sunday produce the lowest engagement of the week, and Sunday in particular shows no dependable peak. If you must post at a weekend, 10 in the morning to 6 in the evening local is the usable stretch.
• Your industry may override this. Technology audiences engage several hours earlier than everyone else, and food engages at lunch. The industry section below has the specifics.

Facebook is a slow burn, not a race: the ranking forgives a late post in a way Reddit's never does

This is the structural difference that changes the whole answer, and it is why the best hour for Facebook is later in the day than the best hour for Reddit.

• There is no shared queue to fight over. Reddit has a single new tab per subreddit, so every post competes with every other post submitted in the same minutes. Facebook assembles each person's feed individually, so there is no equivalent bottleneck and no penalty for posting at a busy hour.
• Posts resurface for hours or days. A Facebook post that is holding engagement keeps being shown to more of your audience long after it was published, including to people who were asleep when you posted. Reddit's Hot score decays on roughly a twelve and a half hour scale whatever you do.
• The consequence is that you optimise for audience, not for competition. On Reddit there is a real argument for posting into an empty early-morning queue with a smaller audience. On Facebook that argument disappears completely, so you simply pick the hour with the most valuable people awake.
• Early engagement still matters, it is just less brutal. The first hour of reactions, comments and shares is the signal that tells Facebook the post is worth distributing further. A slow start caps how far it travels, but it does not kill the post outright.
• Practical upshot: aim at the middle of the shared waking window and do not try to be clever about competition. The clever move on Reddit is the wrong move here.

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

Where the money is: a US or Canadian Facebook user is worth roughly three times a European one and eleven times an Asian one

If your goal is app installs, sales or leads rather than vanity reach, the value of an impression varies enormously by geography, and it should shape which clock you optimise for.

• Meta's own revenue per user tells the story. For full-year 2024, average revenue per user ran at roughly $233 in the United States and Canada, about $68 in Europe, around $21 in Asia-Pacific and about $14 across the rest of the world.
• That is roughly a three to one ratio between North America and Europe, and closer to eleven to one against Asia-Pacific. Advertisers bid that much more for those eyeballs because those users spend that much more.
• User counts point the other way, which is the trap. India has the largest Facebook audience at roughly 582 million users against about 254 million in the United States. Optimising for headcount alone would send you to an audience worth a fraction as much per person.
• Britain is small but valuable and free to include. It is English-first, sits in the high-value European band, and costs you nothing extra if you choose the right hour. That is the entire argument for the midday Eastern window over the American evening.
• Scale, for context. Facebook reports roughly 3.07 billion monthly and 2.11 billion daily active users, so even a narrow high-value slice is an enormous audience in absolute terms.

The overlap problem in plain numbers: America and Britain share only about four genuinely good hours a day

Five hours of separation sounds manageable until you overlay two waking curves. Reading in US Eastern time, here is what happens across the day.

• Before 8 AM Eastern, America is missing. At 6 AM Eastern only about 12% of the American audience is active, even though Britain is already at 74%. Unlike on Reddit there is no compensating advantage, because Facebook has no queue to beat.
• 8 to 11 AM Eastern is the ramp. The American share climbs from roughly 37% to 69% while Britain holds between 74% and 80%. Usable, and this is where technology audiences actually peak.
• 12 to 4 PM Eastern is the shared plateau. Both countries sit at roughly 76% or better across the whole window. This is the only stretch where neither audience is being sacrificed.
• 1 PM Eastern is the peak of the plateau, at roughly 78% American and 88% British active at once.
• After 5 PM Eastern, Britain collapses. By 6 PM Eastern it is 11 PM in London and British activity is down to about 28%. When America finally peaks around 8 PM Eastern at roughly 91%, Britain is at 6%.

Note that the American evening is genuinely excellent if you only care about America, and the Sprout data supports it: Tuesday and Wednesday stay strong through to 8 PM local. The midday recommendation is specifically the price of keeping Britain in the room.

What the largest timing study actually found, day by day, and why "local time" is the detail everyone misreads

Most published timing tables trace back to the same handful of studies. It is worth knowing what the biggest one measured, because one methodological detail changes how you should apply it.

• The dataset. Nearly two billion engagements across about 307,000 social profiles, gathered between 27 November 2025 and 27 February 2026. That is large enough for the day-of-week pattern to be trustworthy.
• The day-by-day result. Monday peaks narrowly at 12 to 1 PM. Tuesday and Wednesday are broad and strong from 12 through to 8 PM. Thursday runs 12 to 2 PM with a second spike at 8 PM. Friday drops off after midday. Saturday has no peak, and Sunday is universally low.
• The critical caveat: those are local times per user, not one global clock. The study aggregates each profile's own audience in its own time zone, so "12 PM" means "noon wherever your followers are", not noon in New York.
• Why that matters for you. If your audience is genuinely single-country, use the local times directly. If it is split across the Atlantic, as most English-language pages are, you cannot satisfy two local noons at once, which is exactly why the overlap analysis above is needed.
• The two answers agree anyway. Midday to mid-afternoon US Eastern is simultaneously inside the American local-time peak and the British early-evening peak, so the compromise costs less than you would expect.

Your industry moves the window: technology posts in the morning, food posts at lunch, finance posts twice

Industry variation in the same dataset is larger than the day-of-week variation, so if your category is listed here it should outrank the platform average.

• Technology and software: 7 to 11 AM on weekdays. The earliest peak of any industry. If you are marketing an app or a developer tool, the general midday advice is genuinely too late for you, and the early window has the pleasant side effect of overlapping the British afternoon.
• Food and beverage: 10 AM to 3 PM, strongest Tuesday and Friday. Tracks meal planning rather than working patterns, and Friday is an exception to the usual weekday decline.
• Healthcare: 10 AM to 1 PM, Monday to Wednesday. A tight window at the start of the week, with little to gain from posting later.
• Financial services: 9 to 10 AM and again 3 to 6 PM on weekdays. Two distinct peaks around the trading and working day rather than one broad band, so a single daily post should pick one.
• Everything else: fall back to 12 to 3 PM Eastern, Tuesday to Thursday, and then measure your own page rather than trusting any of this indefinitely.

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

Facebook forgiving a mistimed post is not the same as Facebook ignoring timing. Early engagement is still the signal that decides how far a post travels.

• Early reactions are a distribution signal. The system reads engagement in the first minutes as evidence the post is worth showing to more of your audience, then to friends of engagers.
• Comments and shares outweigh reactions. A comment is a much stronger signal than a like, and a share stronger still. Posting when your most engaged people are awake is more valuable than posting when the largest number are technically online.
• Reply quickly and the post keeps moving. Answering comments in the first hour extends the window in which Facebook is willing to keep distributing it, which is a genuine free lever.
• A cold start caps the ceiling rather than killing the post. This is the real difference from Reddit. A Facebook post that starts slowly can still recover if something makes it interesting later.
• Which is why the schedule should be sustainable. A post at a slightly worse hour that you are around to engage with beats a perfectly timed post you publish and abandon.

Check your own page before trusting any of this, because your Insights beat every published average

Everything above is a starting hypothesis. Facebook hands you the real answer for your specific audience for free, and it takes a few minutes to read.

• Open Professional Dashboard, then Insights, then your audience. Facebook reports the times your followers are actually online, in your own time zone, based on your real followers rather than a study average.
• Read the geography tab first. Top countries and cities tell you whether the American clock is even the right one to optimise for. A page whose audience is 70% British should ignore the Eastern-time framing entirely and post at 5 to 9 PM UK time.
• Compare your top posts by publish hour. Sort your best-performing posts and note when each went out. A cluster is worth more than any external benchmark.
• Change one variable at a time. Test the same format at two hours across several weeks. Changing hour and content together tells you nothing about either.
• Recheck quarterly. Audience geography drifts as a page grows, and daylight saving moves the US and UK relative to each other twice a year, including a few weeks each spring and autumn when the usual five-hour gap is temporarily four or six.

The whole thing in one glance

• Default: Tuesday to Thursday, 12 to 3 PM US Eastern, which is 5 to 8 PM in Britain. 1 PM Eastern is the single best hour.
• Never optimise Facebook the way you optimise Reddit. There is no queue to beat, so there is no reason to sacrifice audience for quiet hours.
• US-only audience: the American evening is excellent, strong through to 8 PM local on Tuesday and Wednesday. You are just giving up Britain.
• Skip the weekend unless you have data of your own saying otherwise. Sunday is the weakest day on the platform.
• Technology and software should post at 7 to 11 AM instead, which happens to overlap the British afternoon nicely.
• Your own Insights outrank every number on this page. Check the geography tab before adopting any of it.
