LinkedIn Post Date Extractor - the exact date, not just "2mo".

LinkedIn tells you a post is “3w” old and leaves it there. Paste the link and see the exact date and time it went live, down to the second.

Powered by Commentify

The date appears as soon as you paste. Works on post and comment links, and nothing leaves your browser.

Free tool vs. Comment Agent

Checking dates by hand is slow. The Comment Agent does the finding for you.

If you're dating posts to see which are worth commenting on, Commentify's Comment Agent does that job every day. It starts with posts from the last 24 hours on the topics you choose, skips the ones where a comment wouldn't be seen, and comments in your voice.

How it works

Find a post's date in three steps

  1. 01

    Copy the post's link

    On the post, press the three dots in the top right and choose Copy link to post. On a phone, use Share, then Copy link.

  2. 02

    Paste it in the box

    The exact date and time appear as soon as you paste. There's no button to press.

  3. 03

    Copy what you need

    Take the date in your own timezone, or the UTC version if you're citing it or comparing across timezones.

Under the hood

Where the date comes from

A LinkedIn post link contains a 19-digit number, like activity-7500000000000000000. That number is built the same way across the platform: its first 41 binary digits are the moment the post was created, counted in milliseconds since 1970.

The extractor pulls out those digits and converts them to a date. The work happens on your device, so it never loads the post. That also means it works on posts you can't see, as long as you have the link.

Use it for

Why people check a post's date

  • ✓Checking whether a statistic, price or job post is still current.
  • ✓Citing a LinkedIn post, which needs a real publish date.
  • ✓Working out when a claim or announcement was first made.
  • ✓Seeing when a competitor posts, to compare with your own schedule.
  • ✓Deciding whether a post is recent enough to be worth a comment.
FAQ

LinkedIn Post Date FAQ

How do I see the exact date of a LinkedIn post?

+
LinkedIn only shows a rough age like "2mo". On the post, press the three dots and choose Copy link to post, then paste the link into the box above. The exact date and time appear straight away.

How does the extractor know the date?

+
Every LinkedIn post has a long ID in its link, and the first part of that ID is the moment the post was created, stored as a timestamp. The tool reads that part and turns it into a date. LinkedIn doesn't document this, but it has held up across every post we've tested it on.

Is it free? Do I need to log in?

+
It's free with no limits and no signup, and you don't need a LinkedIn login. It runs in your browser, so the link isn't sent to us or to LinkedIn.

Does it show when a post was edited?

+
No. Editing a post doesn't change its ID, so you always get the original publish time.

Does it work on comments?

+
Yes. Open a comment's link (it contains commentUrn) and paste it in. You get the date of the post and the date of the comment.

What about reposts?

+
A repost with your own text is a new post with its own ID, so you get the date of the repost, not the original. To date the original, open it and copy its link.

Why doesn't it work on LinkedIn articles?

+
Articles use a link made from their title, with no ID in it. You don't need the tool for those: LinkedIn shows the publish date at the top of the article.

Why doesn't my lnkd.in link work?

+
Short links hide the post ID. Open the link in your browser, then copy the full address from the address bar.
