LinkedIn Post Date Extractor

LinkedIn only shows relative time, "2mo", "3d". Paste any post, comment, or share URL and see the exact date and time it was published.

No scraping, no API

The timestamp is encoded directly in the post's ID. This runs entirely in your browser, nothing is sent anywhere.

Works on posts, shares, and comments

Any LinkedIn URL with an activity, share, or comment ID in it will decode, paste the whole URL or just the number.

Useful for auditing content calendars

Reconstruct exactly when a competitor, candidate, or your own account posted, without relying on LinkedIn's fuzzy relative timestamps.

How this actually works

›How does this find the exact date of a LinkedIn post?
LinkedIn's post IDs are Snowflake IDs, the same ID scheme Twitter and Discord use. The publish timestamp is encoded directly in the ID's bits: shifting the ID right by 22 bits gives milliseconds since the Unix epoch. No scraping or API access needed, it's pure math on the number already in the URL.
›Why doesn't LinkedIn just show the exact date?
The feed only shows relative time to keep the UI simple. The exact timestamp still exists, it's just embedded in the ID instead of displayed on the post.
›What URL formats work?
linkedin.com/posts/name_title-activity-1234567890123456789, feed update URLs with urn:li:activity: or urn:li:share:, comment URNs, or just the raw numeric ID.

Knowing when a post went out doesn't get you replies.
