Best time to post on social media in 2026, platform by platform

Two of the biggest studies of 2026 looked at TikTok and reached opposite conclusions. Sprout Social's data puts weekends at the bottom for TikTok. Buffer's puts Saturday at the top. Neither is wrong: they measured different accounts, in different periods, with different metrics. That is the most useful thing to know about every "best time to post" chart you will see this year.

So here is the honest version. What the main 2026 studies found for each network, what the platforms themselves say about timing, and a four-week test that tells you the best time for your own accounts, or your clients'.

Why the studies disagree

The two studies most people quote measure different things.

Three things follow. Each study only sees accounts that use that company's tool, so neither is "all of Instagram". Sprout's three winter months may not look like your July. And a median engagement rate, which Buffer uses so that a few viral posts and big accounts do not skew the result, can rank hours differently from a count of engagements.

The good news: both report times in local time, so "Wednesday at 12 p.m." means noon wherever your audience is.

What the platforms say about timing

The networks rank posts; they do not just list them by time. That limits how much the clock can do.

• Instagram. In its ranking explainer, Instagram lists the Feed signals roughly in order of importance: your activity first, then information about the post, which covers how popular it is and "more mundane information" such as when it was posted. Recency is one detail inside the second signal, not the main event.
• TikTok. Its transparency centre names "the time the video was posted" as one video factor, next to the region it was posted from, its length and its hashtags, and alongside what each viewer has recently watched, finished, liked or skipped.
• LinkedIn. Its engineering team described, in 2020, a feed that starts from tens of thousands of candidate posts for each member and ranks them, using the time people spend on a post as one of the signals.
• Pinterest. The advice is about the calendar, not the clock: "If the moment peaks in June, launch in April."

Put simply, the time you post decides who gets the first chance to see it. What happens next depends on whether those people stop, watch and react.

Platform by platform

Every time below is local time, as published by the studies as of October 2026.

TikTok

This is where the studies clash hardest, so it deserves the most care.

• Sprout Social: weekdays win and weekends are the weakest. Its strongest windows are Tuesday 2 to 6 p.m., Wednesday 1 to 8 p.m. and Thursday 1 to 5 p.m., with Monday and Friday at 3 to 5 p.m.
• Buffer (7.1 million posts, published September 2026): the single best slot is Sunday at 9 a.m., followed by Monday at 1 p.m. and Sunday at 1 p.m., and Saturday is the best day overall.

What to do with that: test both. Put one weekday afternoon and one weekend morning in your rotation, and add the peak from your own analytics, which show the hours and days your followers are most active. TikTok counts posting time as one factor among many, so a video that holds attention will keep travelling after its first hour.

Instagram

• Sprout Social: Monday to Thursday, with the widest windows on Tuesday 1 to 7 p.m. and Wednesday 12 to 9 p.m.; weekends are weakest.
• Buffer (9.6 million posts): Thursday at 9 a.m., Wednesday at 12 p.m. and Wednesday at 6 p.m. are the top three slots. Wednesday is the best day; Friday and Saturday are the weakest; 1 to 5 a.m. is the worst time on any day.

Both agree on midweek. Buffer also suggests checking Instagram Insights, which shows when your own audience is most active and often differs from the averages.

Facebook

• Sprout Social: Monday to Thursday, with Tuesday and Wednesday strong from 12 to 8 p.m.; weekends are weakest.
• Buffer (14 million posts): Thursday at 9 a.m. is the single best time, followed by Wednesday at 8 a.m. and Sunday at 10 a.m. Wednesday is the best day and Saturday the worst, and 12 to 5 p.m. is the weakest stretch on most days.

Read those two together: one study's best hours are the other's worst. If Facebook matters for a client, that afternoon is exactly what your test should settle.

LinkedIn

• Sprout Social: Monday to Friday, with Tuesday 11 a.m. to 5 p.m. and Wednesday 11 a.m. to 4 p.m. among the strongest windows; weekends are weakest.
• Buffer (4.8 million posts): generally 3 to 8 p.m. on weekdays, with Wednesday at 4 p.m. the strongest slot and Wednesday the best day, followed by Thursday and Friday.

The two broadly agree: weekdays, from late morning into the afternoon.

X

• Sprout Social: Tuesday to Thursday from 12 to 6 p.m., plus Monday 2 to 3 p.m. and 5 p.m.; weekends are weakest.
• Buffer (cross-platform summary): Wednesday is the best day and Saturday the quietest.

Threads

Sprout Social's study does not cover Threads. Buffer's analysis of 2.5 million Threads posts finds Thursday at 9 a.m. the peak, followed by Wednesday at 12 p.m. and 9 a.m. Weekday mornings from 6 to 11 a.m. see the highest median engagement, Wednesday is the best day, Saturday is the weakest, and Monday also trails the other weekdays.

Pinterest

Sprout Social puts Pinterest on weekdays, mostly mornings into early afternoon (Wednesday 8 a.m. to 1 p.m., for example), with weekends weakest. But on Pinterest the bigger lever is lead time. People plan seasons months ahead, so a Christmas table Pin published on 20 December is late whatever the hour.

How to find your own best time: a four-week test

Studies give you a starting point. Your accounts give you the answer. This test takes four weeks and no special tools.

Three posting windows circled on a weekly grid, ready to be tested against the account's own numbers.

1. Work in the audience's time zone, not yours. Say you manage a bakery in Manchester from Berlin. "Thursday 9 a.m." means 9 a.m. in Manchester, which is 10 a.m. on your laptop. If a client sells in two countries, check where most of their followers are before you pick anything.

2. Pick three windows. One from each study and one from the account's own analytics. For an Instagram account that might be Wednesday 12:30, Thursday 9:00 and the evening peak Insights shows, say 18:30.

3. Rotate them. Post your usual mix, but move each format through every window so that no slot gets all the strong content:

4. Compare reach per post, at the same age. Note each post's reach (or views on TikTok) and engagement seven days after publishing, so every post has had the same time to travel. Compare the median for each window, not the average: one viral post should not crown a time slot.

5. Decide, then retest. Twelve posts is a small sample, so you are looking for a clear gap that repeats week after week, not a difference of a few percent. Keep the winner and test again every quarter, or whenever the audience changes.

If you do this for a client, tell them before you start, so a quieter week does not look like a problem:

Hi Sara, for the next four weeks we will rotate your posts between three time slots (Tue 9:00, Wed 12:30, Thu 18:30) to see which one reaches more of your followers. The content stays the same; only the timing moves. I will share the results in the monthly report.

The results fit naturally into that report; there is more on what to include in our guide to social media reports for clients.

If you plan client content in Julexis, its AI content planner has a "best time" action for the posts in a plan, and the calendar lets you drag any post to the slot your test picked. You can see how it works on the features page.

Key takeaways

• There is no universal best time: Sprout Social and Buffer disagree on TikTok weekends and Facebook afternoons because they measure different accounts in different ways.
• Where they agree, it is on weekdays: midweek for Instagram, late morning into the afternoon for LinkedIn.
• Posting time decides who sees a post first; the ranking decides how far it goes.
• Run a four-week test with three rotating windows, in the audience's time zone, comparing median reach per post.
• On Pinterest, publish weeks or months ahead of the season rather than chasing the hour.
