How to copy a LinkedIn post link to extract its timestamp

What is a LinkedIn Post Timestamp Extractor?

A LinkedIn Post Timestamp Extractor pulls the precise date and time a LinkedIn post or comment was published — directly from its URL. This is a feature that LinkedIn does not expose through its visible interface or metadata.

The tool works by decoding the unique identifier embedded in every LinkedIn post URL. It is useful for content creators, marketers, researchers, and anyone who wants accurate post timing without relying on LinkedIn's vague "3 days ago" display.

No login, no API access, no browser extension required. Just paste the URL.

How it works — decoding the post ID

Every LinkedIn post URL contains a unique 19-digit integer known as the activity ID. For example, in this URL:

https://www.linkedin.com/posts/vishishth_rcrc-redcross-rcrc24-activity-7256595441629249537-mV9A

The number 7256595441629249537 is the post ID — a 64-bit integer that encodes the timestamp of the post.

The tool converts this ID into binary format. The first 41 bits of that binary sequence represent the time in milliseconds since the Unix epoch (1 January 1970). Converting those 41 bits back into a decimal gives the original posting time — accurate to the millisecond.

This timestamp is hidden within LinkedIn's URL structure and is not visible through LinkedIn's frontend or API. This tool makes it readable.

Troubleshooting

URL not recognised
You may have pasted a profile link, article URL, or general LinkedIn page instead of a post link. The URL must contain a 19-digit activity ID.
Result looks wrong
Double-check that you copied the post link and not a share or redirect link. Try copying again from the '...' menu directly on the post.
Post is private
If the post is restricted to connections or a private account, the URL may still work for extraction — the tool reads the ID in the URL, not the post content itself.
Timestamp seems off
The result is your local device time. If you are comparing with someone in a different timezone, the underlying moment is the same — only the display differs.
Frequently asked questions
Does this tool need my LinkedIn login?
No. It works entirely from the post URL. No account access, no API calls, and no LinkedIn authentication required.
Will this work for every LinkedIn URL?
No. It is designed for specific post URLs that contain a 19-digit activity ID. Profile pages, article URLs, and general LinkedIn navigation links will not work.
What if the post was edited?
The tool extracts the original publication timestamp embedded in the post ID — when the post was first created, not when it was last edited.
Can I extract timestamps from multiple posts at once?
Yes. Paste multiple LinkedIn post URLs into the box, one per line. Each result will appear as a separate card. You can then export all results as a CSV file.
Can I use this for OSINT or reporting?
Yes. An exact timestamp helps establish when content appeared on LinkedIn, which is useful in fact-checking, research, and verification workflows.
Can I paste a shortened or redirected link?
Only if the URL still contains the 19-digit post activity ID. Shortened links that mask the full URL will not work directly.
Why does LinkedIn not show the exact post time?
LinkedIn intentionally shows relative times like '3 days ago' rather than exact timestamps. The precise time is encoded in the post ID within the URL but is not surfaced in the interface.
Why is this useful for content managers?
It gives you a precise, verifiable publish time for any post — useful for auditing, scheduling reviews, comparing timing across platforms, and keeping content records accurate.
