Every platform has its own rhythm. Instagram, Facebook and LinkedIn cluster around the workday morning. TikTok and X follow a similar pattern with a second evening bump for TikTok. YouTube shifts to the afternoon on weekdays and mornings on weekends. All times below are EST. Convert them to your own audience’s timezone before you build a schedule around them, since a table built on Eastern time means nothing if your followers are in Manila or Berlin.
Summary table
| Platform | Peak window | Worst times |
|---|---|---|
| 7 AM to 2 PM | Before 6 AM, after 9 PM | |
| TikTok | 9 AM to 12 PM, 7 PM to 9 PM | Before 6 AM, 1 PM to 3 PM |
| 9 AM to 1 PM | Before 7 AM, after 8 PM | |
| 7 AM to 12 PM | After 5 PM, weekends | |
| X (Twitter) | 8 AM to 12 PM | Before 7 AM, after 6 PM |
| YouTube | 2 PM to 4 PM weekdays, 9 AM to 12 PM weekends | Before 9 AM on weekdays |
| 8 PM to 10 PM | Before 8 AM, weekday mornings | |
| Threads | 8 AM to 12 PM | Outside that window |
| Bluesky | 8 AM to 12 PM, 5 PM to 6 PM | Outside those windows |
| Mastodon | 8 AM to 12 PM, 5 PM to 6 PM | Outside those windows |
If you manage more than one channel, the best time to post tool shows all of these at once, converted to your own timezone, so you’re not flipping between separate pages for each platform.

Why these are a starting point and not an answer
Every row in that table is an average across many accounts on that platform, and no single account is average. A B2B account with a professional LinkedIn audience and a teenager’s TikTok account do not share a peak hour, even though both platforms have their own general pattern. Where your audience actually lives matters more than what time zone this table was written in.
If your followers are concentrated in one country or region, use that region’s clock, not EST. The times that actually matter are the ones sitting in your own analytics, not the ones in any blog post, including this one.
How to find your own best time
Pick one platform and one content format you post regularly. Post the same kind of thing at two different times over a few weeks and compare reach, not likes, since reach shows how many people the post reached before anyone reacted to it. Then check that platform’s own audience insights, most of them show you when your followers are actually online, broken down by day.
Do this once per platform. A schedule built from your own data will always beat one built from an aggregate table, this one included. Some teams manage this timing across channels with a tool like BulkPublish, but the method matters more than the tool.
What matters more than timing
Posting on a consistent schedule beats chasing the exact right hour on every platform. The first line of a caption, or the thumbnail on a video, decides whether anyone stops to look, before timing enters into it at all. The format you choose, video, carousel, single image, changes how far a post travels more than a one-hour shift in when you hit publish.
Timing moves a good post a little further at the margin. It does not rescue a post nobody wanted to see.
