What this date tells you

LinkedIn post identifiers contain a millisecond timestamp. This extractor decodes that value without loading the post. Use it to compare the timing of links you already have, or keep a dated record in a spreadsheet.

Treat the result as an ID-derived timestamp, not independently verified publication metadata. It does not reveal an edit history or tell you the best time to post.

Questions about post dates

How do I find the date of a LinkedIn post?
Open the post menu on LinkedIn and choose Copy link to post. Paste the full link into this tool and select Extract date. The tool reads the timestamp encoded in the identifier and shows it in UTC and your selected time zone.
Is this the verified publication time?
No. The result is the timestamp encoded in the supplied identifier. This tool does not open the post or check LinkedIn metadata. It cannot confirm publication, edits, scheduling, visibility, or whether a post exists. For a repost, the result belongs to the identifier in the link, not necessarily the original post.
Does it work with private or deleted posts?
A supported identifier can still be decoded without access to the post. A result does not prove the post is public, still available, or real.
Can I check several links at once?
Yes. Switch to Batch, paste one full post link or supported URN per line, and extract the dates. The CSV includes each input, its result or error, UTC time, and the selected local time zone. Invalid rows do not prevent valid rows from being decoded.
Are my links sent to LinkedIn or an AI service?
No. Extraction and CSV generation run locally in your browser. The tool does not fetch your links, use AI, or require a LinkedIn account or browser extension. Shortened links must be expanded by you before pasting them.

The decoding routine adapts MIT-licensed open-source code. The ID encoding is reverse-engineered and is not an official LinkedIn specification.
