Best Posting Time Calculator

Because the platform baseline hours (11am for Instagram, 7pm for TikTok, and so on) are already expressed in the audience's own local clock time, not anchored to any single UTC moment -- engagement patterns follow local daily rhythms (commute, lunch, evening) that repeat at roughly the same local hour worldwide. "11am" means 11am for a Tokyo audience exactly as it does for a US Eastern one, so there is no UTC offset to apply. An earlier version of this calculator applied a UTC-offset shift and produced backwards advice as a result; that shift has been removed.

Yes -- Industry applies a small fixed adjustment to Best Hour and Second Best Hour on top of the platform and content-type baseline: B2B audiences shift an hour earlier than the B2C baseline (reflecting workday-driven check-in patterns), Creator/Influencer shifts an hour later, and B2C itself applies no adjustment, since the platform baselines are built around a general consumer audience already.

No -- Best Day and Peak Engagement Window don't respond to Content Type, Industry, or Audience Timezone at all. Peak Engagement Window is a fixed +/-2 hour window for every platform, not something that varies by which platform you pick, and Best Day is a fixed weekday drawn directly from the platform's own baseline entry.

Content Type applies its own offset on top of the platform and industry adjustments: Photo/Image content uses the platform baseline unchanged, Video shifts an hour later, Story/Reel shifts two hours later, and Text/Thread content shifts an hour earlier -- reflecting that more time-intensive content formats like video tend to see stronger engagement later in the day when viewers have more attention to give, while quick-read text content performs better earlier. Note this Content Type shift only applies to Best Hour, not Second Best Hour, which tracks the platform's secondary peak unchanged.
