Best time to post YouTube Shorts (2026): what the studies and YouTube say
Two big studies disagree on the best time to post YouTube Shorts, and YouTube says publish time isn't known to affect long-term performance. How to find your own time.
There isn't one best time to post YouTube Shorts. Buffer's analysis of 1.8 million videos puts Friday at 4 p.m. on top. Adobe's analysis of 24,274 Shorts says Saturday at 4 p.m. YouTube itself says publish time "is not known to impact a video's long-term performance." The time worth knowing is when your viewers are online, and YouTube Studio already shows you that.

I build a scheduler, so you'd expect me to hand you a magic hour. I won't. Below is what the two biggest studies found, why they disagree, what YouTube says, and how to find your own time in about a minute.
What the studies say
| Buffer (July 2026) | Adobe Express (July 2025) | |
|---|---|---|
| Sample | 1.8 million Shorts and long-form videos | 24,274 Shorts from 280 creators in 12 categories |
| What it measured | "Median engagement" (not defined further) | Average views, plus likes and comments |
| Best slot | Friday 4 p.m., then Friday 6 p.m. and 7 p.m. | Saturday 4 p.m. |
| Best day | Friday, then Saturday, then Thursday | Tuesday |
| Also found | Weakest: Monday and Tuesday, and afternoons from 12 to 5 p.m. except on Fridays | Shorts posted outside the busy 8 to 10 a.m. window did better than those inside it |

Look at the Tuesday row. Adobe's best day is one of Buffer's worst.
Why the studies disagree
They aren't measuring the same thing.
- Different metrics. Adobe ranks by average views. Buffer reports "median engagement" and doesn't say whether that means views, likes, or something else.
- Different samples. Buffer's 1.8 million includes long-form videos, so fewer of them are Shorts. Adobe's 24,274 are all Shorts, from 280 creators.
- Different years. Adobe's data is from May 2025. Buffer's article is from July 2026.
- Different clocks. Buffer says its times are adjusted so they apply "in your local time", but not whether that's your time or your viewers'. Adobe doesn't say.
The bigger point: both are averages across other people's channels. Your viewers might be students in another time zone, or night-shift nurses, or your mum.
To Buffer's credit, its own article says Shorts are "continuously resurfaced by YouTube's recommendation engine over days or even weeks," so the initial publish time is "less make-or-break". Adobe's version: "While timing might not be everything, it's also not nothing."
What YouTube says
YouTube's help pages are blunt about it.
From the YouTube performance FAQ: "Publish time is not known to impact a video's long-term performance." The recommendation system tries to show the right videos to the right viewers "regardless of when that video was uploaded."
From YouTube's recommendation system page, in a section literally titled "Don't overthink your publish time": "The algorithm aims to deliver the right content to viewers whenever they visit YouTube, regardless of upload time." Publishing when your audience is most active "might lead to more immediate views", but YouTube says it has no evidence that timing changes long-term viewing.
So timing can move your first views. YouTube doesn't think it moves much after that.
When timing does matter
- Your first views. YouTube says posting when your audience is active "can be beneficial for early viewership."
- Live streams and Premieres. YouTube's own exception: "publish time is important for formats such as Live and Premiere videos." Plan those around when your viewers are online.
- Anything tied to a moment. A trend, a launch, last night's match. That one isn't in YouTube's docs. It's just how news works.
How to find your own best time
YouTube Studio has the chart. Per YouTube's help page on understanding your audience:
- Sign in to YouTube Studio.
- Click Analytics in the left menu.
- Open the Audience tab at the top.
- Scroll to When your viewers are on YouTube.
The card shows the days and hours your viewers were on YouTube over the last 28 days, labelled in your local time. Post a little before their busiest hours and you're lined up for those early views.
New channel? The card may say "Not enough viewer data to show this report." That's normal until more people watch. Pick a time you can stick to, post, and check the card again in a few weeks.
Want to test it? Change one thing at a time. Post similar Shorts at two different times for a few weeks and compare views in YouTube Studio. If you change the topic, the hook, and the time all at once, you won't know which one did it.
What about time zones?
The chart is already in your local time. If your viewers' busiest hour is 3 a.m., that's your 3 a.m., and that's the real problem: they're awake when you aren't.
That's what scheduling is for. YouTube Studio lets you schedule a video with a date, time, and time zone, for free. My post on how to schedule YouTube Shorts walks through it.
Where Postminion fits
Postminion doesn't suggest posting times. You pick the date, the time, and the time zone, and the post goes out then. If you think in your viewers' time ("7 p.m. in New York"), set the time zone to theirs and skip the maths. The post keeps that time zone when you edit it.
The reason I built it: I was spending an hour a day re-uploading the same video to five different apps. One upload in Postminion can go to YouTube Shorts, TikTok, Instagram, Threads, Facebook, LinkedIn and Pinterest at the time you pick. How to post one video to TikTok, Reels and Shorts covers that workflow.
What to know on the YouTube side:
- Shorts only. Videos up to 3 minutes and 500 MB. No long-form videos. See YouTube Shorts length and size limits.
- Shorts go out as public at the time you schedule. No premieres, so the one format where YouTube says timing matters most isn't something Postminion does.
- No analytics for YouTube yet. Check the audience chart in YouTube Studio.
If you only post to YouTube, YouTube Studio's scheduler is free and does the job. If the same Short goes to TikTok and Instagram too, try Postminion free for 7 days. The YouTube scheduler page has the overview.
FAQ
What is the best time to post YouTube Shorts?
There isn't one that works for every channel. Buffer's 2026 study of 1.8 million videos found Friday at 4 p.m.; Adobe's 2025 study of 24,274 Shorts found Saturday at 4 p.m. YouTube says publish time isn't known to affect long-term performance. Check when your own viewers are online in YouTube Studio under Analytics, then Audience.
What is the best day to post YouTube Shorts?
The studies disagree. Buffer ranks Friday first and Tuesday among the weakest days. Adobe found Tuesday Shorts got the most views and likes.
Does posting time matter for YouTube Shorts?
A little, early on. YouTube says posting when your audience is active can help early viewership, but publish time "is not known to impact a video's long-term performance." It matters more for Live streams and Premieres.
How do I see when my viewers are on YouTube?
In YouTube Studio, go to Analytics, open the Audience tab, and find the "When your viewers are on YouTube" card. It shows the last 28 days in your local time.
Why does YouTube Studio say "Not enough viewer data"?
YouTube shows that message when it doesn't have enough viewer data for the chart yet. It's common on new channels. Post at a time you can keep up, and check again once more people are watching.
