LinkedIn Post Date Extractor - Free Online

A LinkedIn post date extractor shows the exact date and time a LinkedIn post or comment was published, using only its URL or ID. Paste up to 50 links, pick a time zone, and get a readable date, an ISO 8601 timestamp, a Unix timestamp and the age of each post.

Why Doesn't LinkedIn Show the Exact Post Date?

LinkedIn shows only relative labels such as "3w" or "5mo" next to a post, so the exact publish date is hidden from the page. The date still exists, though. Every post, share and comment has a long numeric ID of about 19 digits, and the leading part of that number stores the creation time in milliseconds.

This tool reads that stored time and turns it into a date you can use. It works with the link shapes you normally copy from LinkedIn: profile and company post URLs that contain -activity-, feed update links with urn:li:activity, urn:li:share or urn:li:ugcPost, comment links, and a bare 19-digit ID.

Which moment does the date represent?

The label on each result tells you what the decoded time means, because different ID types are created at slightly different moments.

The difference matters for scheduled content. A share or ugcPost ID is created when the post is written or scheduled, so it can be earlier than the moment the post went live. When you need the go-live time, use a link that contains the activity ID.

How to Use the LinkedIn Post Date Extractor

You can get a date in under a minute: copy the link, paste it, and press one button. These are the steps, using the labels you see on the page.

1. Open the post on LinkedIn, click the three-dot menu and choose the option to copy the link to the post. For a comment, copy the comment's own link.
2. Paste the link into the box labeled LinkedIn post URLs or post IDs. Add one URL or ID per line, up to 50 lines.
3. Click Extract Dates. Each valid line becomes a result card.
4. Open the Show times in menu and choose Local, UTC or any listed time zone such as Europe/London or Asia/Kolkata. The displayed times update to match.
5. Read the date on each card, then click Copy all to copy every result or Export CSV to save them as a spreadsheet file.
6. Click Load sample to see how the output looks with example links, or Clear to start over.

If you paste a comment link that includes the parent post, the tool decodes both, so you get the comment time and the post time from one line.

Worked Example: Decoding One Post ID

Take the example ID in the input box, 7174373769216000000, pasted on its own line. It has 19 digits, so it passes as a valid ID. Because it is a bare number, the card is labeled Raw ID and the meaning is Encoded time.

After you click Extract Dates, the card shows these values:

• ISO 8601 (UTC): 2024-03-15T12:00:00.000Z
• Unix timestamp: 1710504000 seconds, or 1710504000000 milliseconds
• Age: a relative label such as "1 year ago" or "2 years ago", depending on today's date

Now switch Show times in from UTC to America/New_York. The same moment reads as 8:00 AM on March 15, 2024, because New York was on daylight time (UTC-4) on that date. Nothing about the post changed. Only the clock used to display it did.

Paste the full link https://www.linkedin.com/posts/username_some-slug-activity-7174373769216000000-Ab1c instead and the card is labeled Post (activity) with the meaning Published. The time is the same, but the label tells you it is the publish moment.

How Do You Read and Use the Results?

Each card gives the same instant in four forms, and you pick the one that fits your task. A good result is a card with a plausible date and a clear label. A poor result is a line that was skipped with a warning.

What each output means

• Full date and time in your chosen zone: best for reading, reports and screenshots. Name the zone when you share it, for example "March 15, 2024, 8:00 AM ET".
• ISO 8601 (UTC): the unambiguous format for databases, spreadsheets and audit notes. The trailing Z means UTC.
• Unix timestamp: seconds and milliseconds since January 1, 1970 UTC, handy for scripts and sorting.
• Age: how long ago the post was made, useful for judging whether a claim, statistic or job-market comment is still current.

What to do with an unexpected result

• The time looks several hours off: check the Show times in setting. Local uses your device's zone, which may differ from the author's.
• The date is earlier than the post appeared in your feed: you probably pasted a share or ugcPost link for a scheduled post. Find the activity link for the publish time.
• A line was skipped: the warning means that line had no decodable post ID. Re-copy the link from the post's menu.

Who Needs a LinkedIn Post Date Finder?

Anyone who has to prove or check when something was posted on LinkedIn will find the exact timestamp more useful than "3 weeks ago". Here are realistic situations.

• Researchers and journalists: confirm the order of events when a claim was made before or after an announcement.
• Social media managers: log the exact publish time of competitor and client posts, then compare it with engagement. For planning your own schedule, the best time to post calculator gives a weekly starting point.
• Recruiters and marketers: check whether a quoted post is recent before reusing its data.
• Legal, HR and compliance teams: record a defensible UTC timestamp alongside a screenshot.
• SEO and content teams: date-stamp LinkedIn mentions of a brand or campaign in a content audit.

Best Practices and Troubleshooting Tips

Small habits make the extracted dates more reliable and easier to reuse. These are the mistakes users hit most often.

• Paste one link per line. Several links on the same line can be read as one entry and hide the others.
• Keep the whole URL. Trimming the number off the end of a link removes the part the tool decodes.
• Use full IDs. A bare number should be the complete 19-digit ID. A shortened or mistyped number may decode to a wrong date or be rejected.
• Record the zone. When you export or copy results, keep the ISO 8601 UTC value as your master record and convert for display only.
• Work in batches. A list of 50 posts can be decoded at once and exported to CSV, which beats checking them one by one.
• Check the label. Published, Commented and Created / scheduled are not the same moment. Quote the right one in your notes.

What Are the Limits of This Tool?

The tool decodes the time stored in an ID, so it can only work with links that contain one. LinkedIn article and newsletter pages, profile links and job listing pages do not carry a post ID, so they cannot be decoded here. It also reports when the ID was created, not whether the author later edited the text. Each batch is capped at 50 lines.

The dates cover 2006 onward, and numbers that do not look like valid LinkedIn IDs are rejected rather than guessed. That is deliberate: a clear warning is better than a confident wrong date.

Find Dates on Other Platforms

If your research spans several networks, the same idea works elsewhere. Try the X post date extractor, the Instagram post date extractor or the TikTok post date extractor. Once you know when a post went live, the LinkedIn post formatter helps you polish your own next one, and the YouTube and social media tools hub lists more utilities for your workflow.

Paste your first link into the box above and click Extract Dates to see the exact publish time, then copy or export the results for your notes.
