Best Time to Post on Social Media: Every Platform Compared (2026)
By PostMax Team · Updated · 7 min read
Quick answer
The best time to post on social media is Tuesday to Thursday, in the afternoon, in your audience’s local time. If you post to every platform at once, Tuesday or Wednesday between 2 and 5 p.m. falls inside the best window for Instagram, Facebook, LinkedIn, X and TikTok in Sprout Social’s 2026 data. YouTube is the exception: Buffer found long videos do best on Sunday at 10 a.m.

Here are the best times to post on every major platform, side by side, from the two biggest 2026 studies: Sprout Social (nearly 2 billion engagements across 307,000 profiles) and Buffer (over 52 million posts). Where they disagree, we show both.
Best times to post on each platform
| Platform | Sprout Social | Buffer | Full guide |
|---|---|---|---|
| TikTok | Tue–Thu, 2–6 p.m. | Sun 9 a.m., Mon 1 p.m.; best day Saturday | Every day of the week |
| Tue 1–7 p.m., Wed 12–9 p.m. | Thu 9 a.m.; best day Wednesday | Every day of the week | |
| Tue and Wed, 12–8 p.m. | Thu 9 a.m.; best day Wednesday | Every day of the week | |
| Tue–Thu, 11 a.m.–5 p.m. | Wed 4 p.m., Fri 3–4 p.m. | Every day of the week | |
| X (Twitter) | Tue–Thu, 12–6 p.m. | Tue 9 a.m., Wed 9–10 a.m. | — |
| YouTube | Not covered | Shorts: Fri 4 p.m. Long videos: Sun 10 a.m. | Videos and Shorts |
| Threads | Not covered | Thu 9 a.m.; weekday mornings 7 a.m.–12 p.m. | — |
| Bluesky | Not covered | Not covered | — |
No major study covers Bluesky yet. It’s a text-first feed like X and Threads, so their weekday morning and early afternoon times are a sensible place to start. Test from there.

One time that works when you post everywhere
If you post the same update to every platform at once, you need one time that works for all of them. In Sprout Social’s data, the windows overlap on Tuesday and Wednesday, 2–5 p.m.:
| Platform | Sprout Social window | Covers Tue/Wed 2–5 p.m.? |
|---|---|---|
| Tue 1–7 p.m., Wed 12–9 p.m. | Yes | |
| Tue and Wed, 12–8 p.m. | Yes | |
| Tue–Thu, 11 a.m.–5 p.m. | Yes | |
| X | Tue–Thu, 12–6 p.m. | Yes |
| TikTok | Tue–Thu, 2–6 p.m. | Yes |

TikTok: best time to post today
TikTok has the most detailed data, so we built a tool for it. It shows today’s best times in your audience’s time zone and converts them to your clock. Each platform’s own guide (linked in the table above) has the same tool for that platform.
Weekends and the worst day to post
Sprout Social found Sunday is the worst day across platforms, with the lowest engagement, and it marks weekends as weak for every network it covers.
Buffer disagrees for two platforms. On TikTok, Saturday was its best day and Sunday at 9 a.m. its best single slot. On YouTube, long videos did best on Sunday at 10 a.m. If you post on weekends, those are the places to do it.
Why studies disagree
- Different accounts. Sprout Social’s customers are mostly businesses and larger brands. Buffer’s include more creators and small businesses.
- Different scores. Sprout Social counts total engagements. Buffer uses the median engagement rate per post.
- Your audience is not the average. Nurses, students and office workers are online at different hours.
Use the studies to pick your first times, then let your own numbers take over.
Find your own best times on each platform
| Platform | Where to look |
|---|---|
| Insights → Total followers → Most active times (hours and days). | |
| TikTok | Analytics → Followers: top locations and the hours your followers are active. |
| YouTube | YouTube Studio → Analytics → Audience → When your viewers are on YouTube. |
| Meta Business Suite → Insights. Compare when your best posts went out. | |
| LinkedIn, X, Threads, Bluesky | No simple active-hours chart. Compare engagement on your own posts by the hour they went out. |
Give each new time two weeks before you judge it, and compare posts of the same type. One viral post can make any time look great.
Schedule posts for every time zone
The best times rarely fit your day, especially when your clients’ audiences live in other countries. With a scheduler you write the post when it suits you and it goes out at the right time where the audience is.
In PostMax you write once, pick the platforms, and choose the exact minute. It posts to TikTok, Instagram, Facebook, LinkedIn, X, YouTube, Threads and Bluesky on time, even when your laptop is off.
Frequently asked questions
What is the best time to post on social media?
Weekday afternoons are the safest choice. In Sprout Social’s 2026 study of nearly 2 billion engagements, Instagram, Facebook, LinkedIn, X and TikTok all have strong windows on Tuesday and Wednesday between 2 and 5 p.m. local time. Buffer’s data favors mornings around 9 a.m. for several platforms, so test both.
What is the best day to post on social media?
Tuesday, Wednesday and Thursday. Sprout Social and Buffer both rank midweek days highly for most platforms. TikTok and YouTube are the exceptions in Buffer’s data, where weekends do well.
What is the worst day to post on social media?
Sunday, according to Sprout Social, which found it had the lowest engagement across platforms. Buffer’s data disagrees for TikTok and long YouTube videos, where Sunday mornings perform well.
Should I post at the same time on every platform?
You can. If you post everywhere at once, Tuesday or Wednesday between 2 and 5 p.m. in your audience’s time zone falls inside the best window for Instagram, Facebook, LinkedIn, X and TikTok in Sprout Social’s data. Fine-tune each platform later with your own analytics.
Do these times use my time zone?
