Best Time to Post on Social Media: What the Studies Say

By PostMediaAI6 min read

Short answer: the large published studies broadly agree that weekdays beat weekends and that late morning to late afternoon in your audience’s local time is a safe default. Sprout Social’s 2026 data puts the overall peak on Tuesdays and Wednesdays between 11 a.m. and 6 p.m. local time, with Sunday the weakest day (sproutsocial.com). Beyond that, the studies disagree, so treat any single “best time” as a hypothesis to test on your own account.

Where these numbers come from

Every figure below comes from a social media software company analysing posts made through its own product. That makes the samples large but not neutral: each tool’s customers skew toward certain industries, sizes and regions. Here is what each study says about itself.

  • Sprout Social (2026): nearly 2 billion engagements across roughly 307,000 profiles on Facebook, Instagram, LinkedIn, Pinterest, TikTok and X, from 27 Nov 2025 to 27 Feb 2026, reported in each user’s local time (sproutsocial.com).
  • Buffer: “millions of posts” across major platforms. Buffer’s published methodology compares each post with that account’s own average engagement rather than comparing accounts with each other (buffer.com).
  • Hootsuite (2026): an analysis with Critical Truth of over 1 million posts, with time of day localised across 118 countries (blog.hootsuite.com and blog.hootsuite.com).

Best times by platform, side by side

All times are local to the audience. Where a study lists many windows, we show its headline recommendation; follow the link for the full day-by-day table.

Instagram

  • Sprout Social: Mondays 2–4 p.m., Tuesdays 1–7 p.m., Wednesdays 12–9 p.m., Thursdays 12–2 p.m.; weekends weakest (sproutsocial.com).
  • Buffer: late afternoon, especially 3–6 p.m., with Fridays generating the most interactions (buffer.com).
  • Hootsuite: 3–9 p.m. on Mondays; also 5–8 a.m. and 3–7 p.m. on Tuesdays (blog.hootsuite.com).

LinkedIn

  • Sprout Social: Tuesdays 11 a.m.–5 p.m. is the strongest window; weekends are the worst days (sproutsocial.com).
  • Buffer: 7 a.m.–4 p.m., with a spike around 10 a.m. on Tuesdays (buffer.com).
  • Hootsuite: 4–6 a.m. on Tuesdays and Wednesdays (blog.hootsuite.com).

TikTok

  • Sprout Social: Tuesdays through Thursdays, 2–6 p.m. (sproutsocial.com).
  • Buffer: 4–7 p.m., with Sunday evenings and midweek afternoons standing out (buffer.com).
  • Hootsuite: 7–11 a.m. on Thursdays (blog.hootsuite.com).

Facebook

  • Sprout Social: Tuesdays and Wednesdays 12–8 p.m.; weekends and early mornings weakest (sproutsocial.com).
  • Buffer: 5–7 a.m., with Mondays and Wednesdays strongest (buffer.com).
  • Hootsuite: 9 a.m. on Tuesdays (blog.hootsuite.com).

X (Twitter), Threads, YouTube Shorts and Pinterest

  • X — Buffer: 8–10 a.m., Wednesdays and Tuesdays strongest. Hootsuite: 9–11 a.m. Wednesday to Friday (links above).
  • Threads — Buffer: 7–9 a.m. Hootsuite: 8 a.m. on Tuesdays (links above).
  • YouTube Shorts — Buffer: 3–5 p.m., especially Wednesday to Friday (buffer.com).
  • Pinterest — Hootsuite: 12 p.m. on Tuesdays and Fridays (blog.hootsuite.com).

Why the studies disagree

LinkedIn is the clearest example: Sprout’s best window starts at 11 a.m., Hootsuite’s ends at 6 a.m. Neither is wrong. They measure different customers, different date ranges and different definitions of engagement. Buffer, for instance, defines engagement rate as interactions divided by impressions and normalises each post against the same account’s baseline, which answers “when does a given account do better than usual?” rather than “when is engagement highest overall?” (buffer.com).

Even the vendors say this. Sprout calls its data a baseline you should test against your own account’s performance, and Hootsuite calls its benchmarks “a starting point” (links above). The practical takeaway is to use the overlap — weekdays, daytime, local time — and let your own data decide the rest.

How to find your own best time to post (a 4-week test)

  1. Pick one channel and one content type you post often, such as Instagram carousels or LinkedIn text posts.
  2. Choose two windows to compare, for example 9 a.m. and 5 p.m. in your audience’s main time zone. Use the study overlap above to pick sensible candidates.
  3. Alternate the windows for four weeks, keeping the format and topic mix similar.
  4. Track one metric that matches your goal: reach for awareness, saves or shares for usefulness, link clicks for traffic. Write it into your calendar’s results column the day after each post.
  5. Compare medians, not single posts. One viral post can make any time look like a winner.
  6. Keep the better window, then test it against a new challenger next month.

Time zones: whose 9 a.m.?

Every study above reports times in the audience’s local time. Sprout Social spells this out: a 9 a.m. peak means 9 a.m. in Los Angeles, 9 a.m. in London and 9 a.m. in Sydney (sproutsocial.com). Hootsuite’s free calculator, by contrast, shows its recommendations in Eastern Time and converts them to the zone you select (hootsuite.com). So before you copy a number, check which clock it uses.

If most of your followers live in one region, schedule for that region even if your team works elsewhere. If your audience is split across regions, pick the largest one for your main post and consider a second, adapted post for the next-largest region rather than one compromise time that suits nobody. Your platform analytics usually show where followers are located.

Timing matters less than these three things

  • Consistency. Buffer reports that its most consistent posters received about 5x more engagement per post than inconsistent ones (buffer.com). Our guide to consistent posting covers how to keep a cadence: How to Maintain Consistent Social Media Posting.
  • The first lines and first seconds. A strong hook earns attention at any hour.
  • Being around to reply. Schedule posts for a time when someone can answer comments in the first hour.

Scheduling for your best times with PostMediaAI

Once you know your windows, the hard part is hitting them every week without setting alarms. In PostMediaAI you can batch a week of posts in one session and they publish at the times you set, to the channels you choose (postmediaai.com). Analytics let you compare post performance across channels in one place, with coverage depending on what each network shares (postmediaai.com/faq). PostMediaAI does not pick times for you; you choose them, which is exactly what the 4-week test above is for. For reading the results, see Social Media Analytics for Beginners; for the wider workflow, Social media scheduling guide: workflows, timing, and fewer mistakes; and the pricing page for plans by channel count.

FAQ

What is the best time to post on social media for engagement?

Across platforms, Sprout Social’s 2026 data points to Tuesdays and Wednesdays, 11 a.m. to 6 p.m. local time; Hootsuite’s headline figure is 8 a.m. on Wednesdays (links above). Test both against your own audience.

What is the worst day to post on social media?

Sprout Social found Sunday had the lowest engagement across almost every platform, and Buffer also reports weekends generally underperform (links above). Some niches, such as hobby and local leisure accounts, may differ, so check your analytics.

Does posting time still matter with algorithmic feeds?

Less than it used to, but it still affects how many people see a post early, when engagement signals are first collected. Hootsuite reports Instagram posts with strong first-hour engagement tend to perform better long-term (blog.hootsuite.com).

Should I post at the same time on every platform?

No. The studies above show different windows per network, and audiences use each app at different moments. Schedule each channel separately.
