Methodology in brief. First-party LinkHub data: 657,722 real LinkedIn comments and their impressions, segmented by hour posted (UTC) and by day of the week. Raw hours are in UTC; we give an approximate conversion for a French audience (Paris time ≈ UTC+1 in winter, UTC+2 in summer). Complemented by public industry studies on posts (Buffer, Hootsuite, Sprout Social), cited and dated.
Key takeaways
- The best hours to comment are weekday mornings: the 6–13h UTC window concentrates the strongest impressions (average ~197-203), i.e. ≈ 8am-3pm Paris time in summer. (LinkHub, n = 657,722)
- ⚡ The #1 factor for a comment isn't the hour — it's speed. Commenting within minutes of a post going live (the golden hour) matters far more than the time slot. The opposite of posts, whose publish hour is nearly negligible. (see LinkPost's algorithm study and our delay study)
- The median visibility peak sits around 6–7h UTC (median 43-45), well above the evening. Visibility declines steadily through the afternoon and evening (median ~17-25 at 20–23h UTC).
- Weekdays beat weekends: Monday to Friday, median impressions stay stable (~35-36). Weekends have lower volume and a lower median (Saturday 30, Sunday 28) → less reliable, despite a few averages inflated by outliers.
- Consistent with studies on posts: Buffer and Hootsuite place the best days Tuesday to Thursday and advise against weekends. (Buffer 4.8M posts, Hootsuite 2025)

1. Hours vs delay: two different questions
There are two ways to talk about "timing" on LinkedIn, and they answer different questions:
- The delay after publishing — how long after a post goes out should you comment? That's the topic of our study "when to comment": the golden window is 0–30 min.
- The absolute hour + day — at what time of day, and which day, is it best to be active? That's the topic here.
The two combine: being present at the right time of day raises the odds of being there within the half hour following a post from your targets — the window where the LinkedIn 2026 algorithm distributes most of the reach.
A word from Yannis Haismann, founder of LinkHub. "After analyzing hundreds of thousands of comments, my conviction is clear: for a comment, what matters most isn't the hour — it's speed. Commenting within minutes of a post going live, during the golden hour when the algorithm distributes most of the reach, is by far the most decisive factor. It's almost the opposite of posts: LinkPost's algorithm study puts it bluntly — "the hour you publish is 1% of the result; the content is 99%". For comments, being first to react changes everything. So treat the time of day as a way to be present at the right moment; the real battle is won in the half hour after the post goes out." — Yannis Haismann, based on LinkPost's LinkedIn Algorithm 2026 study.
2. What are the best hours to comment on LinkedIn?
Across 657,722 real comments, we measured impressions by the hour the comment was posted. ⚠️ Hours are in UTC — convert for your audience's timezone (Paris time ≈ UTC+1 winter / UTC+2 summer).
| Window (UTC) | Avg. impressions | Median impressions | Reading |
|---|---|---|---|
| 6–7h | ~197 | 43-45 | Median peak — maximum visibility |
| 7–11h | ~197 | high | Strong morning plateau |
| 11–13h | ~197-203 | high | Midday still very solid |
| 13–17h | declining | declining | Afternoon decline |
| 20h | ~151 | ~17-25 | Clearly weaker evening |
| 23h | ~135 | ~17-25 | Late-evening trough |
Reading. Median visibility peaks in the early morning (6–7h UTC), then holds a strong plateau through midday (≈ 13h UTC). It declines in the afternoon and drops in the evening. In short, for a French audience: commenting in the morning, roughly 7am-2pm Paris time (summer), maximizes the odds of being seen.
This is consistent with what studies on posts show — but note these studies are about publishing posts, not comments. Buffer (4.8M posts) and Hootsuite place the strongest engagement on weekdays, with a strong morning signal (Hootsuite: Tuesday/Wednesday 8–9am). Our data, on the comments side, confirms the same morning pattern at scale.
To be there when the right posts go out, the ideal is to watch your targets: that's exactly the role of personalized feeds — gather prospects and key creators to see their posts as soon as they go live.
3. What is the best day to comment?
On the day of the week side, two findings to read honestly:
- Volume is overwhelmingly on weekdays. Monday to Friday, people comment far more than on weekends.
- Median impressions are stable on weekdays (~35-36, Monday to Friday) and lower on weekends (Saturday 30, Sunday 28).
An important nuance: the weekend shows a higher average of impressions (Saturday ~217, Sunday ~232) even though its median is lower. That gap is the classic sign of a distribution inflated by a few outliers: a handful of viral comments pull the average up, but the "typical" weekend comment is seen less than a weekday one. That's why we lean on the median (more robust): weekdays remain more reliable.
| Period | Median impressions | Avg. impressions | Volume |
|---|---|---|---|
| Monday-Friday | ~35-36 | moderate and stable | high |
| Saturday | 30 | ~217 (outliers) | low |
| Sunday | 28 | ~232 (outliers) | low |
Third-party studies on posts point the same way: Buffer and Hootsuite recommend Tuesday to Thursday and consider weekends the worst time. Sprout Social confirms the weekday advantage.
4. The concrete recommendation
- When: comment on weekdays, in the morning — roughly 7am-2pm Paris time (≈ 6–13h UTC). Avoid evenings and weekends for steady volume (see our 15-30 min/day commenting routine).
- How: combine the hour (this article) with the delay after publishing — commenting within the half hour following the post remains the strongest lever.
- With what: watch your targets via personalized feeds so you don't miss the golden window. To spot the right profiles to follow, see our AI profile recommendation.
FAQ
What are the best hours to comment on LinkedIn? Weekday mornings: our data (657,722 comments) places the median visibility peak around 6–7h UTC and a strong plateau through ~13h UTC, i.e. about 7am-2pm Paris time in summer. Adjust for your audience's timezone.
What is the best day to comment? A weekday (Monday to Friday): median impressions are stable there (~35-36), versus 30 (Saturday) and 28 (Sunday).
Are weekends really worse? Yes for the "typical" comment: its median is lower. The weekend average looks higher but it's inflated by a few viral outliers — hence lower reliability.
Hours vs delay after publishing: what's the difference? The absolute hour is the time of day (this article). The delay is the time elapsed since the post was published — see when to comment on LinkedIn, where the golden window is 0–30 min.
