The best time to post on YouTube, and how much it actually matters
Buffer says Sunday 10am. SocialPilot says weekday afternoons. vidIQ analysed 40.2 million uploads and found the hour barely matters by day 30. Here is what to do with that.

The short answer, and the honest caveat
Publish two to four hours before your audience's daily peak, and if you are picking a day for long-form, weekends have a small edge. That is roughly where the largest datasets land. But YouTube deserves a different answer from Instagram or TikTok, and the honest version is that the hour you upload matters less here than on any other platform you post to. vidIQ looked at 40.2 million US uploads and found the gap between the best and worst upload hour had shrunk to within a few percent by day 30. Day of week held up. Clock hour mostly washed out. That one finding should change how much of your week you spend on this question.
What each study actually found
Buffer analysed 1.8 million YouTube videos and put the top long-form slot at Sunday 10am, with Sunday 9am and Friday noon close behind; for Shorts it found Friday afternoon and evening strongest, at 4pm, 6pm and 7pm. vidIQ's 40.2 million US uploads produced a day-level pattern instead of an hourly one: Sunday runs about 3.5% above a channel's own average, Saturday about 2.2% above, and Wednesday about 2.2% below. SocialPilot, working from 301,000 videos across more than 27,000 channels with engagement normalised per view, disagrees openly, putting long-form at 2 to 4pm on weekdays with Wednesday, Thursday and Friday as the strongest days, and Shorts at midday or early evening. Metricool's study of 799,718 videos from 71,177 accounts adds the context the others skip: 83% of interactions arrive in the first ten days.
Why YouTube's long tail changes the maths
On a feed platform, a post that misses its window is mostly dead. A YouTube video is not. It keeps surfacing through search and suggested for months, which is exactly why the upload-hour advantage vidIQ measured early had largely evaporated by day 30. Metricool's year-on-year comparison points the same way: long-form views rose 76% while engagement fell 45%, a pattern it describes as a slow burn, more reach arriving more slowly over a longer shelf life. Shorts views rose 127% and now account for 61% of all YouTube views. If a large share of a video's lifetime views arrives after week one, from people who searched the topic or got it suggested, the specific minute it went live is a small input into the total.
What upload timing does still affect
Timing is not irrelevant, it is just narrow. What it controls is the first day or two, while YouTube is deciding whether to test your video more widely. Subscribers who have notifications switched on get alerted when you publish, so your upload time is literally when those alerts land; publish at 3am local and the push arrives while they are asleep and is buried by breakfast. Buffer, SocialPilot and vidIQ all give the same practical instruction here, which is rare enough to be worth noticing: publish before the peak, not during it. vidIQ suggests two to four hours ahead, SocialPilot one to two. The reasoning is identical either way. YouTube needs time to process the file, generate captions and run its first tests so the video is ready when your audience shows up.
Shorts and long-form are two different schedules
Buffer and SocialPilot report the same structural split from independent datasets: Shorts and long-form do not peak at the same hours. Buffer's long-form winner is Sunday morning while its Shorts winners cluster on Friday afternoon and evening. SocialPilot puts long-form in the weekday mid-afternoon and Shorts at midday or 6 to 7pm. The mechanism is easy enough to reason about. Long-form is closer to appointment viewing, something people settle into when they have a spare half hour, so it skews toward weekends and evenings at home. Shorts fill the gaps in a day: commutes, lunch, the hour before bed. If you publish one long video a week plus daily Shorts, give each format its own slot rather than stacking everything into one upload session.
Why the studies disagree about the day
The sharpest conflict is over which weekdays work. Buffer's data has Thursday as the weakest day for long-form with Wednesday second weakest, and vidIQ also puts Wednesday below average. SocialPilot names Wednesday, Thursday and Friday the best days. Both cannot be right for the same channel, and the explanation is what sits inside each dataset. SocialPilot's videos come from accounts publishing through a scheduling tool, which skews toward businesses and agencies running weekday workflows. Buffer and vidIQ are reading broader creator populations whose audiences watch on their own time. Time zone handling separates them again, since some studies normalise to the viewer's local hour and others report a single global clock, which on its own can shift a recommendation by several hours.
Find your own window in about ten minutes
Your channel already holds better data than any published average. Open YouTube Studio, go to Analytics, then Audience, and read the chart showing when your viewers are on YouTube. It gives you the actual active hours of the people who already watch you, in your own time zone, which is the only number that matters for the notification and early-signal effects above. Take the strongest band, subtract two hours, and that is your slot. Then leave it alone for a month. Because the day-level differences these studies found sit in the low single digits, you need a lot of uploads before a schedule change is distinguishable from noise. One video that overperformed on a Tuesday is not evidence of anything.
Spend the saved time on the things that move more
Buffer says it plainly in its own write-up: topic, title, thumbnail and how well the video holds attention matter more to long-term performance than the hour. Metricool's finding that only 11% of accounts under 10,000 subscribers moved into a higher tier over the year is a volume and quality problem, not a scheduling one. So make the schedule automatic and stop revisiting it. Record once, cut a week of Shorts in a single sitting with something like FrameOS, and queue them into a fixed slot a couple of hours ahead of your peak. The usual reason a channel misses its best window is not that it picked the wrong hour, it is that nothing was ready to publish.
FAQ
What is the best time to post on YouTube?
Publish two to four hours before your audience's daily peak, which you can read from YouTube Studio's audience chart. Buffer's analysis of 1.8 million videos points to Sunday 10am for long-form and Friday afternoon for Shorts, while SocialPilot's 301,000-video study points to 2 to 4pm on weekdays. Treat both as starting points rather than answers.
Does upload time really affect YouTube views?
Less than most creators assume. vidIQ's analysis of 40.2 million US uploads found the difference between the best and worst upload hour had narrowed to within a few percent by day 30, because search and suggested traffic keep delivering views long after the upload. Upload time mainly shapes the first day or two, when subscriber notifications land and YouTube runs its early tests.
Should I post YouTube Shorts at the same time as long-form videos?
No. Buffer and SocialPilot both found the two formats peak at different hours from separate datasets. Buffer's strongest long-form slot is Sunday morning while its strongest Shorts slots are Friday afternoon and evening. If you publish both, schedule them separately rather than stacking them into one upload session.
What day is best to upload on YouTube?
The studies split. vidIQ found Sunday about 3.5% above a channel's average and Wednesday about 2.2% below, and Buffer also ranks Sunday top and Thursday bottom for long-form. SocialPilot, whose data comes from scheduled business accounts, names Wednesday, Thursday and Friday best. The difference is largely the audience mix in each dataset.
