Short answer: the best time to post on TikTok in 2026 is a weekday afternoon (roughly 2 to 6 p.m.) or an evening between 6 and 10 p.m., in your audience's local time, with Sunday morning around 9 a.m. as a surprisingly strong slot. For Instagram, Wednesday and Thursday perform best, at midday or in the evening. For YouTube Shorts, aim for evenings, with Friday around 4 to 7 p.m. as the top window.
Those windows come from the largest studies published this year, by Buffer and Sprout Social, and they are a good default. But they are averages across hundreds of thousands of accounts, and the studies do not always agree with each other. Below you will find the data per platform and per day, why timing matters less than most people think, how to read your own analytics to find your best time, and how to handle an audience spread across several time zones.

What is the best time to post on TikTok, Instagram and YouTube Shorts?
Four large datasets were published in 2026. All of them express times in local time: 7 p.m. means 7 p.m. where the account (and usually most of its audience) is, not a fixed US time zone. That is important, because older studies often reported times in Eastern or Pacific time, and many articles still copy those numbers without saying so.
Here is the summary per platform, combining both sources.
| Platform | Best days | Best windows (local time) | Weakest |
|---|---|---|---|
| TikTok | Buffer: Saturday, then Monday and Sunday. Sprout: Tuesday to Friday | Weekdays 2 to 6 p.m. (Sprout); Sunday 9 a.m., Monday 1 p.m., Sunday 1 p.m. (Buffer's top 3) | Early mornings; weekends according to Sprout |
| Instagram (Reels and posts) | Wednesday, then Thursday and Tuesday | Thursday 9 a.m., Wednesday noon and 6 p.m. (Buffer); Tuesday 1 to 7 p.m., Wednesday noon to 9 p.m. (Sprout); evenings 6 to 11 p.m. on most days | Friday and Saturday |
| YouTube Shorts | Friday, then Saturday and Thursday | Friday 4, 6 and 7 p.m. (Buffer's top 3); evenings 6 to 11 p.m. on other days | Monday and Tuesday |
If you want one slot per day, here are the top three times for each weekday in Buffer's 2026 studies, ranked from best to third best. You can find the TikTok details in Buffer's TikTok study.
| Day | TikTok | YouTube Shorts | |
|---|---|---|---|
| Monday | 1 p.m., 11 a.m., 8 a.m. | 7 p.m., 6 p.m., 8 p.m. | 8 p.m., 5 p.m., 6 p.m. |
| Tuesday | 6 a.m., 10 p.m., 7 a.m. | 7 p.m., 3 p.m., 5 p.m. | 8 p.m., 9 p.m., 7 p.m. |
| Wednesday | 10 p.m., 6 a.m., 9 p.m. | 12 p.m., 6 p.m., 8 a.m. | 7 p.m., 8 p.m., 9 p.m. |
| Thursday | 1 p.m., 10 p.m., 6 a.m. | 9 a.m., 8 a.m., 7 a.m. | 7 p.m., 8 p.m., 9 p.m. |
| Friday | 6 p.m., 10 p.m., 8 p.m. | 10 p.m., 9 p.m., 6 a.m. | 4 p.m., 6 p.m., 7 p.m. |
| Saturday | 5 p.m., 4 p.m., 3 p.m. | 9 p.m., 10 p.m., 8 p.m. | 7 p.m., 11 a.m., 6 p.m. |
| Sunday | 9 a.m., 1 p.m., 12 p.m. | 9 p.m., 10 p.m., 8 p.m. | 7 p.m., 8 p.m., 5 p.m. |
What about Reels specifically?
Neither study isolates Reels. Buffer looked at all Instagram post types together, and Sprout Social reports Instagram as a whole. In practice, the evening window (6 to 11 p.m.) is the safest bet for Reels, with Wednesday and Thursday as the strongest days. Reels can also reach people who do not follow you through the Reels tab and Explore, so they tend to be less dependent on the exact hour than a feed photo shown mainly to followers.
And YouTube Shorts versus long videos?
Buffer found almost opposite peaks on YouTube: long videos do best in the morning (Sunday 10 a.m. is their top slot), Shorts do best in the evening and on Friday. If you publish both on the same channel, do not use one schedule for the two formats.
Why do the studies disagree, and how much does timing really matter?
Put the two TikTok studies side by side and you get a contradiction. Buffer names Saturday the best day and Sunday 9 a.m. the single best slot of the week. Sprout Social's 2026 data recommends Tuesday to Friday afternoons and lists weekends among the weakest times. Both are honest analyses. They simply measure different things on different populations.
- Different accounts: Buffer's data comes from posts published through its own tool, Sprout's from profiles connected to Sprout, including more than 30,000 of its customers. Two different populations of accounts, and a B2B brand and a meme account do not have the same audience at 9 a.m. on a Sunday.
- Different metrics: Buffer uses the median engagement rate per post (likes, comments, shares and saves divided by followers). Sprout builds its ranking from engagement data (nearly two billion engagements). Neither measures what most small accounts care about first: reach among non-followers.
- Different periods: Sprout's window covers three winter months (late November 2025 to late February 2026). Buffer's Instagram data spans two full years.
- Less competition is also a factor: a slot can perform well partly because fewer accounts post then, not only because more people are scrolling.
The deeper reason timing is a second-order factor is how short-form feeds work. TikTok, Reels and Shorts are recommendation engines: a video is shown to a first batch of viewers, then pushed further if those viewers watch it to the end, rewatch, share or follow. That test is not limited to the first hour. Buffer notes that Shorts in particular keep being resurfaced over days or weeks, which is why their posting time matters less than for a long video. A strong hook posted at a "bad" hour will usually beat a weak video posted at the perfect one.
Posting regularly matters more than posting at the perfect minute, and it is a separate question. If you are wondering how many videos to publish per week, our guide on how often to post on TikTok, Reels and Shorts covers it.
How do you find your own best time to post?
The studies are a starting point. Your audience is the answer. All three platforms show you when your own followers or viewers are active, for free, inside the app. The exact menu names change from one app version to the next, but the reports are easy to find.
Two cautions. First, these reports show when your followers are online, not when they engage with your content, and on short-form platforms most views come from people who do not follow you yet. Second, a small or new account has too little data for these reports to mean much. In both cases, run a simple test.
- Pick two or three candidate slotsFor example, one at lunchtime (12 to 1 p.m.) and one in the evening (7 to 9 p.m.), based on the tables above and your own reports.
- Rotate them for four weeksPublish at a different slot each day, keeping your usual quality and formats. One week of data is noise.
- Compare early results, not totalsNote views, shares and follows after 24 hours for each post. Lifetime numbers mix in the long tail of the feed and hide the effect of timing.
- Keep the winner, test again laterIf one slot is clearly ahead, make it your default. If the difference is small, stop testing: timing is not your bottleneck. Audiences change, so recheck every few months.
A practical rule many creators use: publish a little before the peak hour shown in your analytics, so the first test batch of viewers lands when your audience is arriving rather than leaving.
How do time zones change the best time to post?
Every time in this article is the local time of your audience, not yours. That is easy when you live where your audience lives. It gets tricky when you are a founder in Lisbon selling to Americans, or a brand with followers on three continents.

- Find where your audience is: all three apps show the top countries or cities of your followers or viewers. Use the largest group as your reference time zone.
- Convert, do not guess: 7 p.m. in New York is 1 a.m. in Paris and 4 p.m. in Los Angeles. If you are in Europe and your audience is in the US, your best slot is often late at night or early in the morning for you.
- Split the difference for mixed audiences: for an audience spread between the US East Coast and Western Europe, a US lunchtime post (around noon in New York) lands in the European early evening (around 6 p.m. in Paris). Neither side gets its peak, both get a decent slot.
- Watch daylight saving time: Europe and the US do not change their clocks on the same dates. For a few weeks in March and for about a week around the end of October, the gap between Paris and New York is five hours instead of six. A recurring slot set in your own time zone silently drifts for your audience.
- Consider one account per language: if your audiences are really separate (for example English and French speakers), each account or content line can follow its own schedule instead of one compromise.
How does scheduling help you post at the right time?
Knowing your best slot is useless if you are in a meeting, asleep or on a plane when it comes around. That is the real argument for scheduling: you create content when it suits you, and it goes out when it suits your audience.
A simple routine works for most small teams: once a week, prepare the next week of posts, place them in two or three tested slots per platform, and spend the rest of the week on replies and on reading what worked. Scheduling is also what makes the time zone advice above realistic: nobody wants to wake up at 1 a.m. to post for New York.
This is the workflow Bloomr is built around. Each brand has editorial lines with their own content angles, format mix and language, and Auto Gen drafts posts one after another from those angles: carousels, wall-of-text videos, green screen memes, AI videos, hook + demo videos and UGC videos with AI influencers, in 9:16, 4:5 or 1:1. You keep the drafts you like, then either publish them directly to TikTok, Instagram and YouTube Shorts or schedule them for a date and time. So an English line can go out in the American evening while a French line goes out in the Parisian one, without you being awake for either.
