LinkedIn Post Timestamp & UTC Date Extractor.
LinkedIn hides exact publication dates behind rounded labels like 2w or 4mo. Paste any LinkedIn post link, share URL, or urn:li:activity below to reverse-engineer the exact millisecond UTC timestamp directly from its 64-bit Snowflake ID.

How LinkedIn Snowflake Timestamp Decoding Works & FAQ
How do you find the exact date and time a LinkedIn post was published?
LinkedIn only displays vague relative labels like '1w' or '3mo' in the feed, but every LinkedIn post URL or URN contains a 19-digit 64-bit Snowflake ID (e.g. activity-7258192038471925760). Right-shifting that integer by 22 bits (BigInt(id) >> 22n) reveals the exact Unix epoch timestamp in milliseconds when LinkedIn's servers created the post.
Does this LinkedIn timestamp extractor send my URLs to any server?
No. Decoding happens 100% locally in your browser using JavaScript BigInt bit-shifting in 0ms—making it completely private for OSINT investigations, journalism verification, legal discovery, and B2B competitor social audits.
Does the timestamp change if the author edits the LinkedIn post later?
No. The 19-digit activity or ugcPost Snowflake ID is minted at initial post creation and remains immutable even if the author edits the post copy later.
How can I fetch LinkedIn posts, reactions, and timestamps in bulk via API?
Use GET https://api.linkedindataapi.com/v1/profile/posts, GET /v1/company/posts, or GET /v1/posts/search with zero LinkedIn cookies. Sign up free to get $1.20 (12,000 credits) instantly.
