Best time to post on Instagram: what Instagram says, where to find your hours, and a 14-day test

Search for the best time to post on Instagram and you get tables from scheduling tools. Buffer's 2026 study of 9.6 million posts puts Thursday at 9 a.m. on top. Sprout Social's 2026 data says Wednesday from noon to 9 p.m. Both are averages of other people's accounts, each read in that account's local time.

This guide adds what those tables leave out: what Instagram itself says about timing, where your own followers' active hours are in the app, what "local time" means when your followers live in different time zones, and a 14-day test you can run on your own account.

Hook Studio is an AI reel maker for Instagram and TikTok. It is not affiliated with Instagram or Meta. The platform facts below are as of November 6, 2026.

Instagram's creator FAQ asks the question directly: "What's the best time to post?" The answer: "When your audience is awake and most active. Use your insights to understand their habits." That is the whole official answer. Instagram has not published a best hour, and it has not said how much the hour weighs.

The most detailed official description of ranking is "Instagram Ranking Explained", by Adam Mosseri, the head of Instagram, published May 31, 2023. It says Instagram uses thousands of signals. Time shows up in a few places:

Read together, the official sources point one way: the hour matters most for the people who already follow you, in the first hours after you post. Nobody outside Instagram knows how much post time weighs, so any article that gives you a percentage is guessing.

What is the best time to post reels?

No study we found has a clean answer for reels alone. Buffer says the best time for reels is 6 to 11 p.m., with Wednesday and Thursday strongest. In the same section it says it "looked at all post types together," so "these aren't reels-only slots." Sprout Social says reels follow the same windows as its overall data. Instagram's own list of reels signals has no post time. So post reels when your followers are active, then judge each one by its average watch time.

What the big studies measure

The two studies roughly agree on weekdays, from noon to evening. Both measure other people's accounts, and both read the times in local time. That works when your followers share one clock. When they don't, "local time" stops being one hour. More on that below.

Instagram shows it in your account insights. You need a public professional account, creator or business. Here is the path as of November 6, 2026, from Instagram's help pages on dashboards, date ranges, and insights:

1. 1Go to your profile and tap Professional dashboard. If you don't see it, tap More, open Settings & activity, and tap Insights under For professionals.
2. 2If the dashboard only shows a summary, tap See all insights.
3. 3Pick a preset timeframe at the top: 7, 14, 30, 60, or 90 days. Instagram shows audience details only for presets, not for custom ranges. If 7 days shows nothing, try a longer one.
4. 4Tap Total followers. With at least 100 followers, Instagram shows your growth, the top locations of your followers, their age range, and the times they're most active on Instagram.

How to read it

• Read the hours next to the places. Top locations sit on the same screen. If most followers live in one country, the peak is that country's clock. If they're split across time zones, the peak mixes people on different clocks.
• The chart's time zone is not documented. Instagram's help pages don't say which time zone it uses. The test below uses real clock times on your own phone, so its result doesn't depend on the chart.
• Active on Instagram is not the same as watching you. The chart shows when followers are in the app, not when they interact with your posts. That is why you test.
• Reels also reach people who don't follow you. For them, look at Viewers and Accounts engaged. Instagram breaks both down by top countries and cities.

Under 100 followers

There is no follower chart yet. Use two of Buffer's top times as your test slots, 12 p.m. and 6 p.m., and run the test anyway. Each reel still has its own insights, and those are what the test reads.

Buffer says it normalized its times "so they apply to any timezone." Sprout Social lists its times "in Local Time." Both assume your followers share your clock. A US account with followers on both coasts already has a three-hour spread. Add Mexico, South America, or Spain and it grows.

One post, seven clocks

Here are two of Buffer's top times, Thursday at 9 a.m. and Wednesday at 6 p.m., posted by New York time, and where they land. The times hold from November 1, 2026, the day the US changed its clocks, to March 14, 2027. We computed them with the IANA time zone database (version 2026d).

The gaps move twice a year

The US changed its clocks on November 1, 2026, and changes them again on March 14, 2027. Spain changed on October 25, 2026, and changes again on March 28, 2027. Mexico, Colombia, and Argentina don't change. Mexico dropped daylight saving time on October 30, 2022, under its time zone law. Only towns on its northern border, and the state of Baja California, still change with the US.

So right now Mexico City and Chicago show the same time. From March 14, 2027, Mexico City is one hour behind Chicago, and 9 a.m. in New York is 7 a.m. in Mexico City. If you set your slot by your followers' clock, check it again after each change.

How to pick your two slots

1. 1One country or time zone holds most of your followers: use its clock and ignore the rest.
2. 2Two zones are close: make the best hour for the first one slot A, and the best hour for the second one slot B. The test decides.
3. 3The Americas and Europe: no hour is evening on both sides. 9 p.m. in Madrid is 3 p.m. in New York and 2 p.m. in Mexico City. Test an evening slot for each side.

An example. Say your top locations are New York, Los Angeles, and Mexico City. Slot A could be 6 p.m. in New York, which is 3 p.m. in Los Angeles. Slot B could be 9 p.m. in New York, which is 6 p.m. in Los Angeles and 8 p.m. in Mexico City.

The studies describe other accounts. This test describes yours. You post the same kind of reel at two times for two weeks, swap the times in the second week, and compare every reel at the same age.

Before you start

1. 1Write down your top locations and peak hours from Total followers.
2. 2Pick two slots at least 3 hours apart. Slot A is your peak. Slot B is your best guess for a second peak, or the evening of your second country. Write both in your own time.
3. 3Plan 8 reels in one format. Same structure, same length, a new topic each time. Don't post one reel twice to compare: Instagram's trial reels page warns that content you already shared can get limited reach.
4. 4Keep everything else steady for two weeks: no ads, no collab posts, and no stories that push one test reel and not the others.

The schedule

Four reels a week. Each posting day gets slot A once and slot B once, so the day of the week can't decide the result. Eight reels in two weeks is close to the pace Instagram mentions: its creator FAQ says the creators with the greatest net follower growth post, on average, 10 or more reels a month.

What to write down

• Set a reminder for exactly 24 hours after each reel goes out.
• Then open the reel from your profile, tap its insights, and write down Views and Average watch time. Reels keep collecting views as they age, so compare every reel at the same age.
• A sheet with five columns is enough: date, slot, topic, views at 24 hours, and average watch time.

Instagram defines both on its reel insights page: views count every time the reel starts to play or replays, and average watch time is the average time spent playing it.

Day 15: decide

1. 1Pair the reels by day. Monday of week 1 with Monday of week 2, and so on. That gives four pairs, each with one reel per slot.
2. 2Drop the pairs the content decided. If one reel in a pair has twice the average watch time of the other, the reel won, not the clock. Don't count that pair.
3. 3Count wins. In each pair left, the reel with more views at 24 hours wins for its slot.
4. 4Compare medians. Sort each slot's views at 24 hours and take the middle value. With four reels, that is the average of the middle two. One lucky reel can't move it much.
5. 5Switch only on a clear win. Move to a slot when it has the higher median and wins at least 3 of the pairs that count. Anything less is a tie: keep the slot that's easiest for you. If you dropped two or more pairs, run one more week.

A tie is an answer too. On your account, the hour matters less than the reel, so the effort goes into the first second. Our viral hook examples are a good place to start.

Where trial reels fit

Trial reels are Instagram's way to test a reel on people who don't follow you. Instagram shows them to non-followers first. Your followers don't see them in Feed or the Reels tab, and they stay off your profile unless you share them with everyone. You get their insights within 24 hours, and Instagram evaluates them on their own, so a weak trial doesn't affect how your other reels rank. You need a public account with at least 200 followers for a professional account, or 1,000 for a personal one.

Use them to keep weak ideas out of the test. When you're unsure about a reel, post it as a trial on a day off, and keep a stronger reel for the slot. To post one, turn on Trial before you share. A trial that does well can go to everyone later: open the reel, tap View insights, then Share to everyone.

Don't use trial reels to test the clock. They go to people who don't follow you, so they say nothing about when your followers are online, and Instagram says they may take longer to get views.

The same test works for the best time to post on Facebook. Facebook is a separate app with its own feed, so test it on its own: read your audience in insights, pick two slots, and compare reels at the same age. If you also want Facebook to pay for your reels, read how to monetize Facebook.

Run the test again when your top locations shift, after a clock change in your followers' countries, or every three months.

The test is cleanest when the eight reels share one format and only the topic changes. Hook Studio makes them from a chat: describe the format once, give the agent a new topic for each reel, and download each one ready for its slot. For TikTok, it posts the finished reel to your account when you approve it. See how to make a reel for the full walkthrough, or the content factory to make and schedule reels in batches.

• How much the hour weighs. Instagram has not published it. It names post time as one feed signal among thousands.
• The chart's time zone. Instagram's help pages don't say which time zone the most active times use.
• A sure answer from eight reels. The rules above protect you from one lucky reel. They can't protect you from a slow month or a holiday week. If the result surprises you, run it again.
• A scheduled post from Hook Studio. Hook Studio doesn't schedule. A TikTok post goes out when you approve it, so approve it at your slot. For Instagram, download the reel and post it in the app, or schedule it with Meta Business Suite.

Instagram's help center says Meta Business Suite lets you schedule posts and view insights for both Facebook and Instagram. For what Instagram rewards beyond the clock, read how to grow on Instagram.

Today, open Total followers and write down your top three locations and your peak hour. Pick slot A and slot B, plan eight reels in one format, and put the 14-day schedule in your calendar. On day 15, you'll know your hour, or you'll know the hour doesn't matter much for you.
