Best time to post on LinkedIn calculator: find your own hour from your own posts
Paste up to 20 of your posts — weekday, hour, impressions, likes, comments — and this page scores each hour with LiHelper's public formula, applies the same evidence gate, and tells you your best hour. No sign-up; nothing leaves your browser.
A best-time-to-post calculator works out, from your own posts, which hour of the day has earned you the most engagement per post. Published "best time to post on LinkedIn" charts are averages over millions of other people's posts; your followers may be in another time zone or read LinkedIn at lunch, and only your numbers can tell you. This tool runs the exact calculation LiHelper uses on synced data: score each post as impressions ÷ 10 + likes + 2 × comments, average by hour, and trust a personal hour only once there is enough evidence. It runs entirely in your browser.
Calculator
One post per line: weekday, hour, impressions, likes, comments. Weekdays as Mon…Sun; hours as 0–23 in your own local time (9am and 14:00 also work); write 1200, not 1,200. Up to 20 rows; the example below is already loaded so you can see a result before you paste your own.
Nothing you paste is sent anywhere; clear the box and it is gone.
Result for 8 posts
Your best hour: 08:00
Average score 124.3 per post at 08:00, against a mean of 83.0 across the 3 hours with 2 or more posts. This is a personal hour: the same gate LiHelper applies before it moves your slot.
No other hour clears the gate at least 6 hours away, so post once a day at 08:00 for now.
| Hour | Posts | Avg score | Status |
|---|---|---|---|
| 08:00 | 3 | 124.3 | Best hour |
| 12:00 | 2 | 42.0 | Sampled, below the mean |
| 17:00 | 3 | 69.0 | Sampled, below the mean |
How to use it
- Collect your posts. On LinkedIn open your profile, go to Posts, and for each recent post note the weekday and hour you published, then click "View analytics" for impressions; likes and comments are on the post. Five to twenty posts is enough to start. The LiHelper Connector reads the same numbers automatically if you would rather not type.
- Paste or pick. Enter one post per line in the box, or use the weekday and hour pickers to add rows. Use the hour on your own clock; the app buckets the same way, on the time zone of your profile.
- Read the result. The panel updates as you type. A personal best hour means the gate was met; "not enough evidence" tells you which condition failed and what to post next. The table shows every hour's average score so you can see how close the runners-up are.
The method, in full
1. Score each post
Every post gets impressions ÷ 10 + likes + 2 × comments. Impressions are divided by ten because they are the one number LinkedIn reports for every post — likes and comments sit at zero for many small-account posts, which taught an earlier likes-first version nothing — but they should not swamp real reactions. A comment counts double a like because it costs the reader more and tends to earn further distribution. In the example above, a post with 1,200 impressions, 14 likes and 3 comments scores 120 + 14 + 6 = 140.
2. Average by hour
Posts are grouped by the hour they were published on your own wall clock, and each hour's scores are averaged per post. The weekday is recorded so the app can also show day-and-hour slots, but the hour choice is made across the week, because most people do not have enough posts to trust a single Wednesday-at-8 cell.
3. Apply the evidence gate
- At least 5 posts in total — fewer and a single lucky post decides everything
- At least 2 hours that each hold 2 or more posts — an hour cannot win by default
- The winning hour must score above zero and at or above the weighted mean of those sampled hours
- Ties go to the hour with more posts, then the earlier hour, so the answer is deterministic
- If any condition fails, the answer is the benchmark: 10:00 in your own time zone
4. Space a second post
LinkedIn tests each new post on a small slice of your followers in its first hour; two posts inside that window compete for the same slice. If you post twice a day, the calculator proposes a second eligible hour at least 6 hours from the first, which is the gap LiHelper enforces when Autopilot schedules. The how often to post on LinkedIn guide covers cadence in more depth.
What the calculator cannot know
The same calculation, done for you
Inside LiHelper the free LiHelper Connector syncs impressions, reactions and comments per post from your own LinkedIn tab, so the heatmap fills itself and the best hour updates every time you sync. The scheduler then places Autopilot posts at that hour, six hours from anything else, and publishes them through LinkedIn's official API. On the Free plan that covers posts you write yourself; the 14-day Creator trial every account starts with adds AI drafts written from your profile. The how it works page shows the loop end to end, and the security page explains why no password or cookie is ever stored.
Calculator FAQ
What formula does the calculator use?
Each post scores impressions ÷ 10 + likes + 2 × comments. Posts are grouped by the hour they went out and each hour gets its average score per post. An hour can be your best hour only if you have at least five posts in total, at least two hours each hold two or more posts, and the hour scores above zero and at or above the average of those sampled hours. Otherwise the answer is the benchmark, 10:00 in your own time zone. It is the same calculation LiHelper runs on synced data.
Where do I get impressions, likes and comments per post?
On LinkedIn, open your profile, go to Posts and click "View analytics" under each post; impressions are shown there, likes and comments on the post itself. Note the weekday and hour you published. The LiHelper Connector extension reads the same numbers from your own browser and syncs them, which is how the app builds the heatmap without you typing anything.
Is my data sent anywhere?
No. The calculator runs entirely in your browser; nothing you paste leaves the page and there is no account or sign-up. If you clear the box the data is gone. The app version keeps your synced history so the best hour updates as new posts land.
Why not just post Tuesday at 9?
Published "best time" charts average millions of posts from other people's audiences. They are a reasonable starting point — that is why the benchmark exists — but your followers may be in another time zone or read LinkedIn at lunch. The best time to post on LinkedIn guide explains how to read your own numbers and why the gate above stops one lucky post from picking a bad hour.
