The best time to post on YouTube, and how much it matters
Most timing advice ranks hours without telling you what the gap between them is. On YouTube, one study did the arithmetic, and the answer is small.
vidIQ analyzed 40.2 million uploads from the United States, measuring each upload against its own channel's average day so that channel size could not skew the result. Sunday came out about 3.5% above a channel's average. Wednesday came out about 2.2% below.
On the hour of the day, its finding was blunter still. The exact upload hour barely moves views by day 30, and when videos were grouped by upload hour, the gap between the best and worst hours had shrunk to within a few percent by then.
Keep that number in mind while reading the rest of this page. Everything below is a few percent, and none of it beats making a better video.
The best day to post on YouTube
vidIQ's full week, measured against each channel's own average day.
| Day | Versus a channel's average day |
|---|---|
| Sunday | About +3.5%, the strongest day |
| Saturday | About +2.2% |
| Monday | About even |
| Friday | About -0.5% |
| Tuesday | About -1.4% |
| Thursday | About -1.6% |
| Wednesday | About -2.2%, the weakest day |
Buffer's separate study of 1.8 million videos agrees on the top: Sunday is the best day for long form video, followed by Tuesday and Monday.
That agreement is rare. Two independent samples, measured differently, both put Sunday first. For an audience in one time zone, such as India, the same studies read differently, as YouTube upload time in India explains.
The hour, by day, for long form video
These come from Buffer's analysis of 1.8 million videos and Shorts. Read them as slots to test, remembering that vidIQ found the hour barely moves views by day 30.
| Day | Best hour for long form | Note from the data |
|---|---|---|
| Monday | 9 a.m. | 10 p.m. is a second window. |
| Tuesday | 9 a.m. | One of the best days; 8 to 11 a.m. is consistently strong. |
| Wednesday | 7 a.m. | One of the weaker days, matching vidIQ. |
| Thursday | 5 p.m. | The weakest day for long form in Buffer's data. |
| Friday | 12 p.m. | The only weekday where midday beats the morning. |
| Saturday | 12 p.m. | |
| Sunday | 10 a.m. | The single best slot of the week, with 9 a.m. and 12 p.m. behind it. |
Note how much of this sits in the morning. vidIQ found most creators already upload between 8 a.m. and noon Eastern, and warned that popular does not mean optimal.
Long form and Shorts have opposite schedules
This is the most useful finding on the page, and the one almost nobody applies. Buffer found that long form videos and Shorts peak at nearly opposite times, so publishing both on one schedule costs you performance on one of them.
| Long form | Shorts | |
|---|---|---|
| Best day | Sunday, then Tuesday, then Monday | Friday, then Saturday, then Thursday |
| Best time of day | Mornings | Evenings |
| Top slots | Sunday 10 a.m. | Friday 4 p.m., 6 p.m. and 7 p.m. |
If you publish both formats, that means two schedules. It is the one place on this page where the change is structural rather than a matter of an hour.
Where the studies disagree, and one useful clash
vidIQ and Buffer both name Sunday the best day for YouTube. Sprout Social's cross platform research says Sunday is the worst day to post, yielding the lowest engagement across the board.
Both can be true. Sprout's number covers social platforms generally, where the weekend is quiet, while YouTube is a platform people sit down with on a Sunday. It is a good reminder that a cross platform table applied to YouTube will point you at the wrong day.
The wider lesson holds. Advice written for feeds does not describe a platform where a video keeps being recommended for weeks.
Your own analytics, which vidIQ says should override this page
YouTube publishes the one thing none of these studies can: when your viewers are actually on YouTube.
- Open YouTube Studio and click your profile image in the top right.
- Select Analytics from the left navigation.
- Click the Audience tab at the top.
- Find the module labeled When your viewers are on YouTube. The deeper the color, the more viewers are there at that hour.
- Write down the two blocks that stay dark across several days.
vidIQ is unusually direct about how to weigh this against its own research. Under 1,000 subscribers the heatmap may be too sparse to use, so the benchmarks are a starting point. Past around 5,000 subscribers, your own data should override any generic guide, including theirs.
Publishing before the peak, not during it
Buffer's study makes one practical recommendation: for long form video, publish one to two hours before your audience's peak window.
The reason is mechanical. The upload has to process, be indexed and start being tested before it can be recommended, and a video that goes live exactly at the peak spends the first part of that peak still warming up.
So the number from your heatmap is not the number you schedule. Subtract an hour or two, and publish into the rise rather than the crest.
Premieres, scheduling and the thing that actually breaks schedules
YouTube lets you schedule a video and set it to publish at a fixed time, which removes the main reason most schedules slip: being at a computer at the right moment.
- Schedule the upload rather than aiming to press publish live.
- Upload early. Processing a long video takes time, and a scheduled publish still needs the file ready.
- Use a premiere when there is a reason to gather the audience in one place, and skip it when there is not.
- Keep the day fixed before you worry about the hour, since the day is the larger of two small effects.
- Write the chapters and description before scheduling, since a live video with an empty description wastes the search value; how to use YouTube chapters has the three rules.
Testing a posting time so the result means something
With an effect this small, a sloppy test will find noise and you will believe it.
| Rule | In practice |
|---|---|
| One variable | Same format, length and topic. Only the slot moves. |
| Enough videos | At least five per slot, which on a weekly channel means months. |
| Judge at 30 days | The point where vidIQ found hour differences had mostly equalized. |
| Use medians | One video that took off will move any average you like. |
| Accept a null result | If nothing separates the slots, that is the finding. Pick the one that suits your week. |
What moves YouTube views more than the clock
If the day moves views by about three percent, the rest of your attention belongs here:
- The title and the thumbnail, which decide whether a recommendation becomes a click; thumbnail sizes are in social media post sizes.
- The first thirty seconds, which decide whether the click becomes a view.
- Answering a question people search for, so the video keeps being found after the recommendation stops, the idea behind social media SEO.
- Chapters and a real description, which make a long video navigable and readable.
- Publishing at all, on a rhythm viewers can learn.
A schedule a channel can actually keep
- Pick a fixed day before you pick an hour, because viewers remember days.
- Read your own heatmap in YouTube Studio and publish one to two hours before the dark block.
- Give Shorts their own slot, in the evening, separate from long form.
- Schedule uploads rather than publishing by hand.
- Stop optimizing after one test. At three percent, this question is finished and the content is not.
The same comparison of studies for short video is in the best time to post on TikTok and on Instagram. Getting that rhythm in place, and then spending the saved time on titles and openings, is what social media management looks like on video, and the free social media audit starts with the titles rather than the timetable.
How we will test this
Not run yetEverything above comes from the published sources listed below, and nothing here is presented as something we measured. Our own test on live accounts has not been run yet.
This is the test we will run: we publish on our own channel in two fixed slots for a quarter, comparing medians at 30 days, and record what the When your viewers are on YouTube heatmap reports for that channel over the same period.
Platforms change behavior without announcing it, so once the first test is run we repeat it every quarter, and this section will say when it was run and on which devices and app versions.

Questions people ask next
What is the best time to post on YouTube?+
vidIQ's analysis of 40.2 million uploads found the exact hour barely moves views by day 30. The day matters slightly more: Sunday runs about 3.5% above a channel's own average.
What is the best day to post on YouTube?+
Sunday, in both studies read here. vidIQ puts it about 3.5% above average, and Buffer names it the best day for long form video.
What is the worst day to post on YouTube?+
Wednesday, about 2.2% below a channel's average day in vidIQ's data. Buffer also rates Wednesday and Thursday among its weakest.
How much difference does the upload hour make?+
Very little. vidIQ found the gap between the best and worst hours had shrunk to within a few percent by day 30.
Do Shorts and long form videos share a schedule?+
No. Buffer found nearly opposite peaks: long form in the mornings and on Sunday, Shorts in the evenings and on Friday.
When is the best time to post a YouTube Short?+
Buffer's top three Shorts slots are all on Friday: 4 p.m., 6 p.m. and 7 p.m.
Where do I see when my viewers are online?+
YouTube Studio, then Analytics, then the Audience tab, in the module called When your viewers are on YouTube.
Should I publish at the peak or before it?+
Before. Buffer advises publishing one to two hours ahead of the peak so YouTube can process and start testing the video.
Does any of this matter for a small channel?+
Less than you would hope. vidIQ says that under 1,000 subscribers your heatmap may be too sparse to use, and past about 5,000 your own data should override any generic guide.
Should I spend time optimizing posting time at all?+
Run one test, pick a day you can keep, then stop. At a few percent, the title, the thumbnail and the first thirty seconds deserve far more of your week.
