The best time to post on every platform in 2026 (data-backed)

Every article about posting times says the same thing: "the best time to post is when your audience is online." Useful! Thanks!

So we did the work. We looked at engagement data from 4,200 posts published through Mediux over the last six months. We broke it down by platform, by industry, and by region. Here's what we found — and the bit nobody tells you up front.

The bit nobody tells you

Posting time matters less than you think. We see engagement variance of about 18–22% between "best" and "worst" times within a given audience. Content quality variance is 5–10x that. If you're spending more than 5 minutes a week thinking about posting time, you're optimising the wrong thing.

That said, if you're going to post anyway, you might as well post when people are looking. So here are the actual numbers.

Instagram

Best windows (across all industries):

• Tuesday – Thursday, 11am – 1pm local
• Wednesday, 7pm – 9pm local (the strongest single window we saw)
• Sunday, 9am – 11am for evergreen content

Avoid: Monday mornings before 10am, Friday after 5pm, Saturday between 12pm and 4pm. These are when feeds are loudest, not when people are present.

TikTok

TikTok's algorithm is far less sensitive to posting time than the others — the For You page surfaces content for days after upload. But we still see two patterns:

• 9pm – 11pm local — highest first-hour engagement
• 12pm – 2pm local — second peak, especially Tuesday and Thursday

If you're posting trend-based content, get it up within 24 hours of the trend breaking — much more important than time of day.

LinkedIn

LinkedIn is the most timing-sensitive platform we tracked. Weekend posts get less than half the reach of weekday posts.

• Tuesday and Wednesday, 8am – 10am — clearly the strongest window
• Thursday 11am – 1pm, second-best
• Avoid weekends entirely unless the content is industry news worth reading on Sunday

Facebook

Engagement on Facebook has flattened into a long mid-day curve:

• Monday – Friday, 1pm – 4pm local for organic posts
• Saturday morning if you're targeting older demographics

X (Twitter)

X is real-time, so it's less about time of day and more about being there when something is happening. The patterns we see:

• Weekday mornings 8am – 10am — commuter window
• Tuesday – Thursday 6pm – 8pm — second peak
• Threads do best when posted between 10am and 12pm

YouTube

YouTube's first-24-hour engagement matters more for the algorithm than time of day. But we see slight preference for:

• Thursday – Saturday, 2pm – 4pm local for long-form
• Daily 8pm – 10pm for Shorts

Industry adjustments that actually matter

Generic timing data is useful as a starting point. These industry adjustments mattered enough to be worth noting:

• B2B SaaS: shift everything 1–2 hours earlier. Audience checks at start of workday.
• Fashion & lifestyle: Sunday is your single best day, especially for outfits and hauls.
• Food & restaurants: hour before mealtimes outperforms any other window.
• Fitness: 5am – 7am and 6pm – 8pm. Around workouts, not in the middle of the workday.

How to actually find your time

Use this data for the first month. Then ignore it and look at your own analytics. Your audience is not the average audience. After 30 posts, you'll have enough data to see your own patterns — that's the only chart that matters.
