LinkedIn Post Date Extractor
LinkedIn shows “3w”. The link knows the second. Paste a post or comment URL to check the exact date and time it was published.
Post ⋯ → “Copy link to post”, or comment ⋯ → “Copy link to comment”. A comment link is the comment’s time, not the post’s. Nothing is sent anywhere.
How it works
How to check the exact date of a LinkedIn post?
Open the post itself
Not the profile — find the post in the feed, or on the profile under Activity → “Show all posts”.
Copy the link to the post
⋯ on the post → “Copy link to post”. Or open it and copy the address bar.
For a comment, copy its own link
⋯ on the comment → “Copy link to comment”, so you get the reply’s time, not the post’s.
Paste it here
The date appears as you paste — local time, UTC, and how long ago.
What you get
The time LinkedIn does not print
Exact, not “2w”
Date and time to the second, where LinkedIn shows a rounded, ever-shifting relative age.
Local and UTC
Your timezone for reading, UTC for a report or a timeline someone else has to trust.
Comments too
A comment link decodes to the comment’s time, so you can see how many minutes after the post a reply came.
Any post link shape
/posts/…-activity-…, /feed/update/urn:li:activity:…, ugcPost and share urns, or just the 19-digit id on its own.
No login, no API
The time is inside the id in the link you already have. Nothing is fetched from LinkedIn.
Done properly
The id is a 64-bit number, past what JavaScript’s plain numbers hold; it is decoded with BigInt so the low bits are not silently corrupted.
Where it pays off
Who needs the exact date of a LinkedIn post?
Fact-checking a claim
Someone says they “posted about this months ago”. The id in their link says exactly when. The same for a screenshot dispute: paste the link and you have the minute.
OSINT, journalism and research
Building a timeline of who said what and when needs fixed timestamps, not “3w”. Decode each link once and the order of events stops moving under you.
HR and legal records
A post or comment that matters in a dispute needs its publication time on record. This is the time LinkedIn itself minted, in UTC, from the URL.
Finding your posting window
Line up exact publish times of your own posts against their reactions and you can see which hours actually work for you — instead of guessing from “1mo”.
