Fill in the field above to get started.
Find your starting windows
Use your recent public posts to choose a timing test. No login needed, and the results describe how your past posts performed.
Enter your account
Enter your public Instagram handle. The result shows the times in your browser's time zone.
Compare your posting hours
See how your newest posts performed by weekday and time of day, compared with your other posts.
Select a window to test
Pick one of the strongest windows shown. From 8 posts the tool shows windows. With fewer than 20, use the result as a first hint.
How to read the heatmap
The heatmap splits your week into seven days with six four-hour blocks each, in your browser's time zone.
A cell
all your posts published on that day in that block.
The number in a cell
how those posts did compared with your other posts. 1.0 means "same as usual", 1.5 means one and a half times as well.
The windows
up to three cells with at least two posts that sit above your usual level. An empty cell only means you haven't posted there yet.
How the score is built
The tool compares your posts only with your own account.
Collect posts
your newest public posts. If you post several times a day, the tool keeps reading until a full week is covered, up to 96 posts. Pinned posts don't count.
Let fresh posts settle
A post counts once it's three times as old as your usual gap between two posts, at least three hours and at most two days.
Score each post
likes, plus comments counted twice and shares three times. Each post is compared with the median of the ten posts closest to it in time, so a growing account doesn't skew the result.
Rein in outliers
A single viral post counts at most eight times as strongly, and every cell is pulled toward the middle. A cell with one lucky post can't look like a sure thing.
How much you can trust it
How far the result goes depends on how many posts count and how many days they cover. If your posts span less than three days, the result stays at low at most, and under seven days at medium at most.

From window to test
A window is a hunch you check.
Pick one window
the highest one on the list that fits your day. The order also weighs how many posts back a window, so a well-backed window can come before a higher number.
Compare similar posts
for two to three weeks, similar content in the new window and at your usual time.
Check again
Enter your handle again and see whether the cell holds up.
What the tool doesn't measure
It shows when your posts did well, not when your followers are online. Instagram shows active times in Insights once you have 100 followers. If you always posted at the same time, the tool can't rate other times.
Set your test times in the Instagram scheduler, and see whether a post in the new window did better with post statistics.
Common mistakes
Copying generic studies
Your audience isn't the average.
Deciding after one post
One outlier isn't a pattern.
Reading empty cells as bad
They just have no posts.
Changing everything at once
Test one window at a time.
What is the best time to post on Instagram?
There is no universal best hour, so start with the posting windows that look strongest for your own account. Your content, audience and time zone all affect which hours are worth testing. Crowdbird turns recent public posts into an account-specific starting point, so you can choose a window based on your own posting history.
How does the best time to post on Instagram calculator work?
The calculator sorts your newest public posts into four-hour blocks by weekday and time of day. Each post is compared with the ten posts closest to it in time, scored by likes, comments counted twice and shares counted three times. You get a weekly heatmap in your browser's time zone and up to three stronger windows, fewer if your account has little posting history. The results describe past posts and can't predict your next one.
What are peak posting hours on Instagram?
Peak posting hours can mean either hours when followers are active or hours associated with stronger post performance. Those are different measurements. Crowdbird uses the second: reactions to posts published at particular times. When someone recommends a peak hour, ask which audience, time zone and measurement it refers to before adding it to your calendar.
Can I see when my Instagram followers are most active?
Yes, Instagram's Total followers insights include active times when you have at least 100 followers. You can use that information alongside your content insights to plan a timing test. Crowdbird's public tool does not access that follower activity information, so its suggested windows should not be read as a count of followers currently online.
How many posts do I need for a useful result?
Crowdbird shows windows from 8 posts and marks the result as a first hint below 20. From 40 posts spread over at least a week it rates the confidence as high. Very fresh posts don't count yet because their numbers are still growing. More posts help less than you'd think if you always publish at the same time, so test a few different times before making a window part of your regular schedule.
Can I use the calculator with a private Instagram account?
No, the calculator can only read public accounts and public posts. You do not need to log in to use it with an eligible handle. If you prefer to keep your account private, record your own posting times and results instead, then compare similar posts across a few candidate windows without changing your privacy settings.
Why does my heatmap stay the same after I publish?
Public post data is cached for 12 hours, so a newly published post may not appear immediately. Give the tool time to refresh instead of repeatedly submitting your handle, and avoid changing your schedule based on the early response to one new post.
