The best time to post on Instagram on Monday is the afternoon into early evening, roughly 2 p.m. to 7 p.m. in your audience's time zone. Sprout Social's 2026 data puts the Monday peak at 2 to 4 p.m. Hootsuite's 2026 study stretches it from 3 to 9 p.m. Buffer's single best Monday slot is 7 p.m.
Monday is also a good day to post in general. Sprout Social counts it among the four strongest days of the week, Hootsuite names it one of three peak days, and Later's 2026 report goes further and calls Monday the best day of the week on Instagram. The odd one out is the hour: Later found 5 a.m. and 11 p.m. did best on Mondays.
If you post once on Monday, start at 3 p.m. local time, the hour where Sprout Social and Hootsuite overlap. Then test an evening slot against it. Your own Most active times chart in Instagram Insights is the tiebreaker. Below is the data behind each Monday window, who each slot suits, and a simple four-week test.
Best time to post on Instagram on Monday: the data at a glance
| Study | Best Monday time | Data behind it |
|---|---|---|
| Sprout Social (updated March 2026) | 2–4 p.m. | Nearly 2 billion engagements across about 307,000 profiles, Nov 2025 to Feb 2026 |
| Hootsuite (July 2026) | 3–9 p.m. | Over 1 million posts, localized to 118 countries |
| Buffer (September 2026) | 7 p.m., then 6 p.m. or 8 p.m. | 9.6 million posts from 200,000+ accounts, Jan 2024 to Dec 2025 |
| Later (April 2026) | 5 a.m. and 11 p.m. | 6 million+ posts, Jan to Oct 2024 |
All four report times in the audience's local time zone. Three of the four land somewhere between 2 p.m. and 9 p.m., which makes Monday afternoon and evening the safest bet.
Is Monday a good day to post on Instagram?
For most accounts, yes. Here is how each study ranks it:
- Sprout Social: Monday through Thursday are the best days. Weekends have the lowest engagement.
- Hootsuite: Monday, Tuesday and Thursday show peak engagement.
- Later: Monday is the best day overall, and also the best day for Reels.
- Buffer: Wednesday is best, followed by Thursday and Tuesday. Friday and Saturday are the weakest. Monday sits in the middle.
So Monday is never the worst choice, and in two studies it is near the top. What the studies cannot tell you is whether your followers behave like the average. That is what the test plan below is for.
Monday time slots, from early morning to late night
Early morning (5 a.m. to 8 a.m.)
What the data says: Later found 5 a.m. was the top Monday slot in its study. Hootsuite's industry breakdown shows consumer goods and retail brands doing best from 7 to 11 a.m. on Mondays.
Who it suits: retail and consumer brands, and accounts whose followers live a few time zones ahead of you.
Tip: schedule it the night before. Nobody should set an alarm to post.
Late morning to lunch (10 a.m. to 1 p.m.)
What the data says: none of the four studies names this as the Monday peak. It sits just before Sprout Social's 2 p.m. start and Hootsuite's healthcare window of 1 to 3 p.m. on Mondays.
Who it suits: local businesses promoting lunch, and B2B accounts that want to catch people at their desks.
Tip: use it for a second Monday post, not your main one, until your own numbers say otherwise.
Afternoon (2 p.m. to 4 p.m.)
What the data says: this is Sprout Social's Monday peak, and 3 to 4 p.m. also falls inside Hootsuite's window. Hootsuite's healthcare data points to 1 to 3 p.m. on Mondays.
Who it suits: most brands, B2B accounts and healthcare. It is the best first test for nearly everyone.
Tip: post your strongest feed post or carousel of the week here, since two studies agree on it.
Early evening (5 p.m. to 7 p.m.)
What the data says: it sits inside Hootsuite's 3 to 9 p.m. range and includes Buffer's 6 p.m. runner-up slot. Buffer also found Reels in general perform best between 6 p.m. and 11 p.m.
Who it suits: creators, consumer brands and audiences who work a standard daytime schedule.
Tip: a good slot for Reels. Test it against your afternoon post with similar content.
Evening (7 p.m. to 9 p.m.)
What the data says: Buffer's best Monday hour is 7 p.m., with 8 p.m. as a runner-up. Hootsuite's window runs until 9 p.m.
Who it suits: food, lifestyle, entertainment and education accounts.
Tip: carousels that take time to read fit well here, since people have more time in the evening than at lunch.
Late night (11 p.m. to midnight)
What the data says: Later found 11 p.m. performed well on Mondays, and its Reels data points to 12 a.m., with Monday as the best day for Reels.
Who it suits: accounts with followers spread across several time zones, where late night for you is evening for them.
Tip: treat it as a wildcard. Only one study supports it, so test it after you have a baseline.
Monday slot comparison
| Window | Backed by | Good for | Watch out for |
|---|---|---|---|
| 5–8 a.m. | Later; Hootsuite retail data | Retail, consumer goods, followers in earlier time zones | Must be scheduled ahead |
| 10 a.m.–1 p.m. | No study as a Monday peak | Lunch offers, B2B | Weaker evidence than the afternoon |
| 2–4 p.m. | Sprout Social, Hootsuite | Most brands; your first test | Your own followers may peak later |
| 5–7 p.m. | Hootsuite, Buffer | Reels, creators, consumer brands | Check it against Most active times |
| 7–9 p.m. | Buffer, Hootsuite | Lifestyle, food, education | Sprout Social's data does not support it |
| 11 p.m.–12 a.m. | Later | Reels tests, global audiences | Only one study supports it |
How to find your Monday peak in Instagram Insights
- Switch to a professional account (Creator or Business) if you have not already. Personal accounts do not get Insights.
- Go to your profile and tap Professional dashboard.
- Tap See all next to your account insights, then open Total followers.
- Scroll to Most active times. The Days view shows how Monday compares to the rest of the week.
- Open the Hours view and, if your app shows a day picker, select Monday to see its busiest hours.
Follower activity only appears once you have at least 100 followers. If you are below that, start with the 2 to 4 p.m. window and track each post's reach.
Plan your Monday posts with ViralFarm
Monday posts are easiest when you make them on Friday. With ViralFarm you can queue a Monday 3 p.m. carousel and a 7 p.m. Reel in one sitting, see them on the calendar, and let them publish on time. The same post can go to TikTok, Threads or Facebook with a caption written for each channel.
If the slots are easy but the posts are not, ViralFarm's AI builds Instagram carousels from a link, a topic or pasted text, using templates modeled after posts that went viral. Edit the slides, then schedule. You can also connect it to Claude or ChatGPT through MCP and ask your agent to fill next Monday's slots. The free plan includes 2 channels and 20 published posts a month.
A 4-Monday test plan
- Monday 1: post at 3 p.m. This is your baseline.
- Monday 2: post a similar piece at 7 p.m.
- Monday 3: post at the peak hour from your Most active times chart.
- Monday 4: repeat the best slot so far, and add one wildcard (5 a.m. or 11 p.m.) if you want to test Later's findings.
Keep format and topic similar so time is the main variable. Compare reach, saves and shares about three days after each post. After four Mondays you will have a better answer than any study can give you. For the rest of the week, see our guide to the best time to post on Instagram.
Frequently asked questions
What is the best time to post on Instagram on Monday?
Between 2 p.m. and 7 p.m. in your audience's time zone is the safest range. Sprout Social's 2026 data shows a 2 to 4 p.m. peak, Hootsuite's shows 3 to 9 p.m., and Buffer's top Monday hour is 7 p.m.
Is Monday a good day to post on Instagram?
Yes. Sprout Social ranks Monday among the four best days, Hootsuite lists it as a peak day, and Later calls it the best day of the week. Buffer ranks Wednesday first but still places Monday ahead of Friday and Saturday.
What is the best time to post a Reel on Monday?
Try the evening first. Buffer found Reels do best between 6 p.m. and 11 p.m. on any day, and Monday's top Buffer slot is 7 p.m. Later found midnight works best for Reels, with Monday as the top Reels day, so a late slot is worth one test.
Should I post on Instagram on Monday morning?
Only if your audience is up early or you sell consumer goods. Later found 5 a.m. worked well on Mondays, and Hootsuite's retail data favors 7 to 11 a.m. For most accounts, though, the afternoon has stronger support.
What time zone should I use for Monday posts?
Use the time zone where most of your followers live. All four studies report local times, so 3 p.m. means 3 p.m. for your audience. Your top locations in Instagram Insights show where that is.
How many times should I post on Monday?
One feed post or Reel is enough for most accounts. Add Stories if you use them: Buffer suggests posting Stories daily, ideally once or twice a day. Post more only if you can keep the quality up every week.
Start with 3 p.m., test 7 p.m., and let four Mondays of data pick your slot. When you want those posts made and scheduled ahead of time, ViralFarm can handle both. Start free with ViralFarm, no credit card required.
