Have you ever scrolled through LinkedIn, found an incredibly useful post, and wondered exactly when it was published?
If you look at the timestamp, LinkedIn only gives you a vague estimate like "2w" (two weeks ago), "3mo" (three months ago), or "1yr" (one year ago).
For marketers, researchers, and content creators, "about three months ago" is not good enough. You need the exact date and time to analyze trends, cite sources, or understand a creator's LinkedIn content strategy.
Fortunately, there are a few simple ways to find the exact publishing date of any LinkedIn post. In this guide, we will show you how to extract the exact timestamp from a LinkedIn post URL.
Why Does LinkedIn Hide the Exact Post Date?
LinkedIn intentionally obscures the exact publishing date to make the feed feel "evergreen."
When you see a post from "1yr" ago, you are less likely to dismiss it as outdated than if you saw a specific date from over a year ago. This design choice helps LinkedIn keep older, high-performing content circulating in the feed longer.
However, the exact timestamp is still there - it is just hidden inside the post's unique URL structure. Every time someone publishes a post, LinkedIn generates a unique "Activity ID" that contains the exact millisecond the post was created.
Method 1: Use an Online LinkedIn Post Date Extractor (Easiest)
The fastest way to find the exact date of a LinkedIn post is to use a free online LinkedIn Post Date Extractor.
These tools do the complex math for you by decoding the Activity ID hidden in the post URL.
Step 1: Copy the LinkedIn Post URL
Go to the LinkedIn post you want to analyze. Click the three dots (...) in the top right corner of the post and select Copy link to post.
The URL will look something like this:
https://www.linkedin.com/posts/username_activity-7164283940123456789-AbCd
Step 2: Use an Extractor Tool
Search Google for a "LinkedIn post date extractor" (there are several free options available).
Paste your copied URL into the tool. The tool will instantly extract the hidden Activity ID (7164283940123456789) and convert it into a human-readable date and time, adjusting for your local timezone.
Method 2: Manually Extract the Date Using the Activity ID (Advanced)
If you do not want to use a third-party tool, you can decode the timestamp yourself. This method requires a bit of technical knowledge, but it reveals exactly how the system works.
Step 1: Find the Activity ID
Look at the URL you copied from LinkedIn. The Activity ID is the long 19-digit number located right after the word "activity-".
Example URL:
https://www.linkedin.com/posts/username_activity-7164283940123456789-AbCd
In this example, the Activity ID is 7164283940123456789.
Step 2: Convert to Binary
This 19-digit number is a specific type of database identifier called a "Snowflake ID." To get the date, you first need to convert this decimal number into binary code. You can use any free decimal-to-binary converter online for this step.
Step 3: Extract the Timestamp
Once you have the binary number, take the first 41 bits (the first 41 digits).
Convert those 41 bits back into a decimal number. The resulting number is the UNIX timestamp in milliseconds (the number of milliseconds that have passed since January 1, 1970).
Step 4: Convert to a Readable Date
Finally, paste that UNIX timestamp into an "Epoch Converter" or UNIX timestamp converter website. This will translate the milliseconds into an exact calendar date and time.
How to Find the Exact Date of Your Own LinkedIn Posts
If you are trying to find the exact date of your own LinkedIn posts, you do not need to extract the Activity ID. LinkedIn provides this data in your analytics.
- Go to your LinkedIn profile.
- Scroll down to the Analytics section.
- Click on Post impressions.
- Here, you can see a list of your recent posts along with their exact publication dates.
You can also export this data. If you go to your Page or Creator Analytics and export your content data as a CSV file, the spreadsheet will include a column with the exact publish date and time for every post. This is highly useful for measuring your LinkedIn posting frequency and analyzing what times yield the best engagement.
Summary
LinkedIn's decision to hide exact dates with vague labels like "1mo" can be frustrating when you need precise information. But by using a LinkedIn post date extractor or decoding the Activity ID yourself, you can always uncover the exact moment a post went live.
Whether you are studying competitors, tracking trends, or auditing your own LinkedIn content calendar, having the exact timestamps gives you a massive analytical advantage.
If you are looking to create posts that stand out regardless of when they are published, try formatting your text first. Use the LinkedIn Preview Tool to add bold text, italics, and custom spacing to make your content pop in the feed.
