Aleksandr SamokhinThe best time to post on social media is a weekday from midday to late afternoon in your audience's local time. Sprout Social's 2026 analysis of nearly 2 billion engagements puts the cross-network peak at 11 a.m. to 6 p.m., with Tuesday and Wednesday strongest and weekends weakest. Its network-level windows are wider, from 10 a.m. on Pinterest to 9 p.m. on Instagram.
That average hides big differences between networks. Buffer's 2026 data puts the top TikTok slot on Sunday morning and the top LinkedIn slot at 4 p.m. on Wednesday. On some networks, timing barely changes how far a post travels.
This guide collects the best times for eight networks in one table, explains which networks reward good timing and which mostly ignore it, and links to a dedicated article for each one. It finishes with a starter week and a simple way to test your own hours.
What is the best time to post on social media?
The best time to post on social media is midday to late afternoon on Tuesday or Wednesday. Sprout Social's 2026 study names "midday to late afternoon, between 11 a.m. and 6 p.m." local time as the overall window. It reached that conclusion from nearly 2 billion engagements on about 307,000 profiles, collected between November 27, 2025 and February 27, 2026. It found that Tuesdays and Wednesdays show the highest peak engagement on almost every platform, and that Sunday is the worst day.
Buffer's 2026 network studies agree on midweek but not always on the hour. Its top slots for Instagram, Facebook, and Threads are 9 a.m. on Thursday, and its top X slot is 9 a.m. on Tuesday. So a safe default is one post per network between late morning and mid-afternoon, Tuesday through Thursday. Then check the network table below, because TikTok, YouTube, and LinkedIn break the pattern.
What is the best time to post on each network?
Weekday slots from late morning to late afternoon work on most networks. Use these starting points in your audience's local time; sources are in the table below.
- Instagram: Tuesday 1–7 p.m. or Wednesday 12–9 p.m. (Sprout Social); Buffer's top slot is Thursday 9 a.m.
- TikTok: Tuesday to Thursday 2–6 p.m. (Sprout Social); Buffer finds evenings from 6 to 11 p.m. strongest. Timing matters least here.
- Facebook: Tuesday and Wednesday 12–8 p.m. (Sprout Social); Buffer's top slot is Thursday 9 a.m.
- LinkedIn: Tuesday to Thursday from 11 a.m. (Sprout Social); Buffer's top slot is Wednesday 4 p.m.
- X: Tuesday to Thursday 12–6 p.m. (Sprout Social); Buffer's top slot is Tuesday 9 a.m.
- YouTube: long-form on Sunday at 10 a.m. and Shorts on Friday at 4 p.m. (Buffer).
- Pinterest: Tuesday to Thursday 10 a.m.–1 p.m. (Sprout Social); Pins keep earning for months.
- Threads: weekday mornings from 6 to 11 a.m.; Buffer's top slot is Thursday 9 a.m.
Best times to post on social media by network
The table summarizes two consistent sources. Sprout Social published one cross-network study on March 31, 2026, with all times in local time, counting reactions, comments, shares, direct messages, and clicks. Its network pages add detail, so the table follows them where they differ from the summary page (on TikTok, for example, the network page narrows the best days to Tuesday through Thursday). Buffer published a separate study for each network during 2026, based on median engagement and adjusted so the times read as local time. All pages were reviewed on October 4–5, 2026.
| Network | Sprout Social best window (local) | Buffer top slot | Best days | Weakest days | Full guide |
|---|---|---|---|---|---|
| Tue 1–7 p.m., Wed 12–9 p.m. | Thu 9 a.m., then Wed 12 p.m. and Wed 6 p.m. | Tue–Wed (Sprout); Wed, Thu, Tue (Buffer) | Sat and Sun (Sprout); Fri and Sat (Buffer) | ||
| TikTok | Tue–Thu 2–6 p.m. | Sun 9 a.m.; evenings 6–11 p.m. peak | Tue–Thu (Sprout); Saturday (Buffer) | Sunday, then Saturday (Sprout); Wed and Thu (Buffer) | TikTok |
| Tue and Wed 12–8 p.m. | Thu 9 a.m.; weekday mornings beat afternoons | Mon–Thu (Sprout); Wed, Thu, Tue (Buffer) | Weekends, Sunday lowest (Sprout); Saturday (Buffer) | ||
| Tue 11 a.m.–5 p.m., Wed 11 a.m.–4 p.m., Thu 11 a.m. and 1–5 p.m. | Wed 4 p.m., then Fri 3 p.m. and Fri 4 p.m. | Tue–Thu (Sprout); Wed, Thu, Fri (Buffer) | Weekends (Sprout); Monday, then Tuesday (Buffer) | ||
| X | Tue–Thu 12–6 p.m. | Tue 9 a.m.; weekday 9–11 a.m. | Tue–Thu (Sprout); Wednesday (Buffer) | Saturday (both) | X (Twitter) |
| YouTube | Not covered | Long-form Sun 10 a.m.; Shorts Fri 4 p.m. | Long-form Sun, Tue, Mon; Shorts Fri, Sat, Thu | Long-form Thu and Wed; Shorts Mon and Tue | YouTube |
| Tue–Thu 10 a.m.–1 p.m. | No Buffer study | Mon–Fri (Sprout) | Weekends (Sprout) | ||
| Threads | Not covered | Thu 9 a.m.; weekday mornings 6–11 a.m. | Wed, Thu, Tue (Buffer) | Saturday, then Sunday (Buffer) | Threads |
Buffer's samples differ by network: about 9.6 million Instagram posts, 7.1 million TikTok posts, 14 million Facebook posts, 4.8 million LinkedIn posts, 8.7 million X posts, 1.8 million YouTube videos, and 2.5 million Threads posts. Each guide linked in the last column compares four or more studies for that network, including sources such as Hootsuite, SocialPilot, Later, and PostFast.
Where do the two studies agree and disagree?
They agree on the shape of the week. Both name Wednesday as a strong day for Instagram, Facebook, LinkedIn, and X, although Buffer ranks Tuesday second-weakest on LinkedIn. Both name Saturday as the weakest day on X. LinkedIn hours are also close: Sprout's Wednesday window runs from 11 a.m. to 4 p.m., which is Buffer's top slot.
They disagree on the hour for Facebook and Instagram, where Buffer favors 9 a.m. and Sprout favors midday to evening. The sharpest split is TikTok. Sprout finds Tuesday-to-Thursday afternoons, while Buffer finds Sunday morning first, Saturday as the best day, and Wednesday as one of the weakest. Two big datasets pulling in opposite directions suggest that, on TikTok, the posting hour is a weak lever.
Three reasons explain most of these gaps. The studies count different outcomes (Sprout counts total engagements; Buffer uses median engagement or engagement rate). They sample different customers. And pooled averages let large accounts tilt the result toward the hours they happen to post. The X guide explains these effects in more detail.
What is the best day to post on social media?
Wednesday is the most reliable day across the networks where both studies rank days. Sprout Social found that Tuesdays and Wednesdays show the highest peak engagement across almost all platforms. Buffer names Wednesday the best day for Instagram, Facebook, LinkedIn, X, and Threads.
The weakest days are at the weekend: Sunday in Sprout's cross-network data, and Saturday in four of Buffer's seven network studies (Instagram, Facebook, X, and Threads). Three exceptions matter:
- TikTok: Buffer names Saturday the best day and Sunday 9 a.m. the top slot.
- YouTube: Buffer finds Sunday best for long-form videos and Friday best for Shorts.
- Wednesday on TikTok and YouTube: Buffer ranks Wednesday among its weakest days on both (TikTok: Wednesday and Thursday; YouTube long-form: Thursday and Wednesday).
So start with Wednesday on Instagram, Facebook, LinkedIn, X, and Threads, and pick days for TikTok and YouTube from their own data. Brands that sell to students, parents, gamers, or hobbyists should run one weekend test slot before ruling weekends out.
How much does posting time matter on each network?
Posting time matters most where a post is shown mainly to followers soon after it goes live, and least where a recommendation system or search decides who sees it. Each network mixes these distribution models differently, so the value of good timing changes too.
Three terms help here. A follower feed shows posts from accounts you follow, so a post competes for attention when those followers are online. A recommendation feed picks posts for each viewer based on predicted interest, including from accounts they do not follow. Search surfaces posts when someone looks for a topic, which can happen months later.
| Network | Main distribution (official source) | Timing sensitivity (my read) | What to prioritize |
|---|---|---|---|
| Feed mixes followed and recommended accounts; Stories come from followed accounts; most Reels come from accounts you don't follow (Instagram) | Moderate | Post feed content when followers are active | |
| TikTok | For You feed; follower count is not a direct ranking factor (TikTok) | Low | The first seconds and watch time |
| Feed from people, Pages, and groups you follow, plus suggested content (Meta) | Moderate | Posts that start conversations among followers | |
| Connections, follows, groups, and relevant posts outside your network; recency is one ranking signal (LinkedIn) | Moderate | Working-hours posts you can reply to | |
| X | For you recommendations plus a Following timeline of followed accounts (X Help Center) | High | Posting when you can join the replies |
| YouTube | Home and Up Next recommendations, subscriptions, and search (YouTube) | Low for search; higher for Shorts | Titles, thumbnails, and search intent |
| Engagement-driven distribution with no set engagement window (Pinterest) | Low | Keywords and a weekly publishing cadence | |
| Threads | Followed profiles blended with recommended content (Meta) | Moderate | Morning posts and replies |
The "timing sensitivity" column is my judgment from the distribution model and the data below, not a platform statement. Pinterest is the clearest case: its help center says a Pin can gain engagement "hours, days, months, or even years" after it is published.
What controlled data shows
One 2026 study tested this directly. PostFast analyzed 61,008 posts on Instagram, TikTok, Facebook, and YouTube over the 90 days to September 4, 2026. PostFast is itself a scheduler, and the report is self-published from its own users' data. Each post was compared with the median of the account that published it, so a few large accounts posting at 3 p.m. cannot make 3 p.m. look good for everyone. On Instagram, the swing between the strongest and weakest hour of the day shrank from 5.5x with pooled data to 1.43x with the controlled method. The chart below uses the best and weakest hours from PostFast's summary table instead, so its Instagram range is narrower (0.96 to 1.20).
The results match the feed types only partly. On TikTok, no hour with at least 300 posts beat the account's normal by 5% or more, which fits a recommendation feed. Instagram had one clear hour (3 p.m. at 1.20x) and Facebook had two (3 p.m. and 5 p.m.). YouTube, where the sample was mostly Shorts, showed the largest effect: 1 p.m. at 1.25x against 6 p.m. at 0.80x.
PostFast analyzed LinkedIn separately, using 1,836 company Page posts from 60 Pages. Its hour curve did not reproduce when tested, and weekend posts ran ahead of Thursday, on small samples. PostFast did not measure X, Pinterest, or Threads, so the table above relies on the distribution model alone for those three. The practical lesson still holds: a modest timing gain is real on some networks, but it is smaller than the gap between a strong post and a weak one.
How can you find your own best time to post?
The tables above tell you where to start testing, not where to stay. Pooled studies average thousands of accounts, and yours may behave differently. The four-week test fixes that by comparing each of your posts with your own normal performance, not with other accounts.
- Pick three slots per network. Choose one morning, one midday, and one later slot in your audience's time zone, starting from the table above.
- Rotate comparable posts. Spread formats and topics evenly across the slots, with four or more posts in each.
- Score each post against your median. Timing index = a post's reach, views, or impressions at 48 hours ÷ your median post. An index of 1.00 is normal, and 1.25 means 25% above your usual post.
- Keep a clear winner, then retest. Switch only when one slot leads the others by roughly 20% or more. Repeat the test every quarter.
The full version of the four-week test, with a worked example and a scoring table, is in the X guide. The method is the same on every network; only the metric changes. Use views on TikTok and YouTube, impressions or reach on Instagram and Facebook, and impressions on LinkedIn and X.
Native analytics can narrow your starting slots. Instagram shows the times your followers are most active once you have at least 100 followers, according to Instagram's Help Center. YouTube Studio has a "When your viewers are on YouTube" report that YouTube recommends for planning Premieres and live streams.
Once you have a winner, turn it into a routine. Cadence, weekly planning, and a regular review are covered in the guide to building a consistent social media posting schedule.
How do you choose times for audiences in several time zones?
Both main studies report results in the audience's local time. Schedule for where your followers live, not where you live. If they are spread across regions, look for the hours where their days overlap.
| Audience | Starting slot | Why it works |
|---|---|---|
| One region | That region's best window | Use the table above as written |
| Across the United States | 12–2 p.m. ET (9–11 a.m. PT) | Lunch on the East Coast, mid-morning on the West Coast |
| UK and US East Coast | 3–5 p.m. UK (10 a.m.–12 p.m. ET) | London's afternoon overlaps New York's late morning |
| Western Europe | 11 a.m.–3 p.m. CET | One window covers most of the region |
| Global | Two slots about eight hours apart | No single hour reaches every region in daylight |
For a global audience, consider splitting by network. For example, aim LinkedIn at the region where your buyers work and TikTok or Instagram at the region where most of your viewers are.
Daylight saving time changes these gaps. In 2026, Europe returns to standard time on October 25 and the United States on November 1. For that week, New York is four hours behind London instead of five. Recheck cross-region slots each March and late October.
A starter weekly schedule for three networks
To get going this week, schedule three posts per network between Tuesday and Thursday. The example below uses LinkedIn, Instagram, and X, a common mix for founders and small teams. Each slot comes from the studies above.
| Day | X | ||
|---|---|---|---|
| Monday | Plan the week | Plan the week | Plan the week |
| Tuesday | 11 a.m. (Sprout window) | 6 p.m. (Sprout and Buffer evening) | 9 a.m. (Buffer top slot) |
| Wednesday | 4 p.m. (Buffer top slot) | 12 p.m. (Buffer and Sprout) | 1 p.m. (Sprout window) |
| Thursday | 1 p.m. (Sprout window) | 9 a.m. (Buffer top slot) | 4 p.m. (Sprout window) |
| Friday | Review results | Review results | Review results |
Each network gets one morning, one midday, and one later slot, so the schedule doubles as the four-week test. No two networks publish in the same hour, which leaves time to reply to comments on each post. After four weeks, keep the slots that beat your median and replace the ones that do not.
Write a separate version of each idea for each network instead of pasting one caption everywhere. Check the image, video, and caption specs for each network before you schedule, especially when one asset feeds three formats.
Common timing mistakes
- Using one "best time" for every network. A 9 a.m. slot can suit X and Threads, while TikTok and YouTube Shorts often do better in the evening in Buffer's data.
- Copying a study's time zone. Sprout and Buffer use local time, but some studies report in Eastern Time. A 9 a.m. ET slot is 6 a.m. in California.
- Publishing to every network at once. You cannot reply in three places at the same moment, and early replies help posts on follower-driven feeds.
- Judging a slot by one post. A single viral post can make any hour look perfect. Use at least four posts per slot and compare medians.
- Fixing timing before fixing content. On TikTok, the clock barely moves results. A stronger hook will usually do more than a new hour.
- Treating search networks like feeds. Pinterest and YouTube search reward keywords and consistency more than a precise publishing hour.
Schedule posts at your chosen times with PostQuest
A timing test only works if posts go out at the same times every week, which is the job of a scheduler. PostQuest is the scheduler I build for founders, creators, and small teams. It publishes to all eight networks in this guide, plus Bluesky and Mastodon. See how it works on each network in the social media scheduler guides.
These features matter most for a cross-network schedule:
- A weekly calendar. Give each network its own slots and see all of them in one view.
- Platform-specific captions. Write a different version of the post for each network from one draft.
- Pre-publish checks. PostQuest checks each network's caption and media rules before a post is scheduled, then shows each post's publishing status, with retry handling for failed posts.
- Per-post analytics. Views, reach or impressions, and engagement counts synced from each network where the network exposes them, with the publish time. LinkedIn personal profiles, YouTube click-through rate, and Pinterest outbound clicks are not synced, so read those in the native tool.
- AI assistant access. Connect Claude through the PostQuest MCP server and ask it to sort your recent posts by publishing hour. Anything the assistant creates is saved as a draft until you approve it.
PostQuest does not suggest best times automatically, and it does not have a best-time feature. Buffer and Sprout Social can recommend posting times from your own history, so choose one of them if that matters most to you. PostQuest includes a seven-day trial; see the current plans.

Quick answers
Frequently asked questions
What is the worst time to post on social media?
Weekends are the weakest period overall, and Sprout Social names Sunday the worst day across platforms. Late evening, from 6 to 11 p.m., is weak on X and Threads in Buffer's data. That rule does not hold everywhere: Buffer finds evenings strongest for TikTok and YouTube Shorts, and its Instagram evening peak comes from all formats pooled, not Reels alone. Avoid weekend and late-evening slots by default, then test them if your audience is active outside office hours.
Should I post at the same time on every network?
No. Each network peaks at different hours, so one shared slot will be wrong for at least some of them. Buffer's top LinkedIn slot is 4 p.m. on Wednesday, while its top Threads slot is 9 a.m. on Thursday. Staggering posts also lets you reply to early comments on each network. Schedule each network at its own best window and adjust after testing.
Does posting time matter if an algorithm decides who sees my post?
Less than most guides suggest. On TikTok, PostFast found no hour that beat an account's normal by 5% or more. Timing is likely to matter more on X, LinkedIn, and Facebook, where followers see posts soon after publishing. That is my read from the distribution model: PostFast did not measure X, and its LinkedIn Page data showed no reliable hour effect. Even there, a strong post usually beats a better hour.
How often should I update my posting times?
Review your slots once a quarter, and sooner if your audience shifts, for example after a launch that brings followers from another region. Studies change too: Buffer republished its TikTok and LinkedIn studies in September 2026. Run the four-week test again, compare each slot against your median, and move a slot only when another one wins clearly.
