Best time to post on YouTube: long-form vs Shorts

If you're posting your 20-minute masterpiece and your 20-second Short on the same schedule... you're basically making them fight in the parking lot.

New data floating around this month suggests the "best time to post on YouTube" isn't one answer anymore. It's two. And if you ignore that, you're leaving free momentum on the table. Not forever. But long enough to be annoying.

What happened

A fresh analysis of ~1.8 million YouTube uploads (mixed: long-form + Shorts) looked at median engagement by day and hour. The punchline: long-form and Shorts peak at almost opposite times.

For long-form, the top slot was Sunday around 10 a.m. (morning wins in general, roughly 8-11 a.m.). The strongest days clustered around Sunday, then Tuesday, then Monday. The weakest stretch showed up midweek, especially Wednesday/Thursday and a lot of weekday early-afternoon windows.

For Shorts, the energy flipped: evenings were the hotspot (roughly 6-11 p.m.). And the top three slots were all on Friday - late afternoon into evening (think 4 p.m., 6 p.m., 7 p.m.). Best days were Friday, then Saturday, then Thursday, with Monday/Tuesday dragging at the bottom.

The study also claims the times are meant to be read in your local timezone (so you're not doing timezone math at 1 a.m. like a maniac).

And the bigger backdrop matters: YouTube's CEO said Shorts are now averaging 200+ billion daily views, and viewers watch over 1 billion hours of YouTube on TVs every day. ([blog.youtube](https://blog.youtube/news-and-events/neal-mohan-cannes-2025/))

Why creators should care

Attention: long-form and Shorts get discovered differently. Shorts are snackable feed behavior. Long-form is more "sit down and stay a while" behavior - more living-room, more habit-driven, more "I've got 30 minutes." That Sunday-morning bump starts to make psychological sense when you remember how many people treat YouTube like TV now.

Distribution: posting time won't magically save a weak video. YouTube even shows a note in Studio that publish time isn't known to directly affect long-term performance. ([reddit.com](https://www.reddit.com/r/NewTubers/comments/vssdcx?utm_source=openai)) But "long-term" is doing a lot of work in that sentence. Early traction still decides who gets the first wave of impressions - especially from subscribers, notifications, and the initial browse push.

Monetization: if long-form is your revenue engine (ads, sponsors, memberships, long watch sessions), you want your first few hours to land when people are actually able to watch. Shorts can be your daily reach machine, but it tends to spike fast and fade fast - so timing windows matter more there.

Workflow: the underrated win here is operational. If long-form "belongs" to mornings and Shorts "belong" to evenings, you can publish both formats without cannibalizing your own audience. You're not competing with yourself. You're taking two turns.

Creators love obsessing over posting time because it feels controllable. Meanwhile their first 15 seconds are a snoozefest. Fix the controllables that matter more... then use timing like seasoning.

What to do next

Split your calendar on purpose. Treat long-form and Shorts like two shows. Start by testing Sunday morning for long-form and Friday evening for Shorts as your baseline, then adapt to your niche.
Use your own heatmap, not someone else's. In YouTube Studio, check the "When your viewers are on YouTube" chart (it's based on recent behavior). If you don't see it yet, that usually just means you don't have enough viewer data. ([reddit.com](https://www.reddit.com/r/NewTubers/comments/uqu7q3?utm_source=openai))
Publish slightly before the peak. Don't drop exactly on the darkest block. Give it a bit of runway so processing is done and notifications have time to land. (Especially if you upload in 4K. YouTube loves taking its sweet time.)
Run a boring 4-week experiment. Same format, similar topic difficulty, two consistent time slots. Track first-hour click-through rate, first-day watch time, and whether it pulls in returning viewers. The goal isn't a viral lottery ticket. It's a reliable lift.
Stop making Shorts "random." If Shorts are your reach lever, schedule them like a real product: evenings, with a heavier bias toward Thu-Sat. Then use them as a bridge: one Short that tees up the long video, one that clips the best moment after it's live.
