How to Check Hundreds of LinkedIn Post Dates at Once
Need to find the dates of multiple LinkedIn posts? Checking every URL separately takes time, especially when you are working on a content audit, competitor research, or a large spreadsheet.
Every LinkedIn post URL contains a unique Post ID. The first 41 bits of that ID contain the post’s timestamp. This is the same method used by the single LinkedIn Post Date Extractor, but this tool applies it to your entire list at once.
How Bulk Date Extraction Works
For every URL you enter, the tool:
- Finds the Post ID inside the URL
- Converts the Post ID to binary
- Extracts the first 41 bits
- Converts those bits into a Unix timestamp
- Displays the timestamp as a readable date and time
Doing this manually is possible, but repeating the process for hundreds of links is slow and leaves more room for mistakes.
That’s Why I Created This Tool
Paste up to 1,000 LinkedIn post URLs, one per line, and click Extract Date & Time.
The tool processes every URL and displays the results in one table. Each result includes:
- The exact post date and time in UTC
- The date and time in your timezone
- Date only in UTC and your timezone
- Time only in UTC and your timezone
- ISO 8601 format
- Unix timestamp
- The Post ID
You do not need to open each post or repeat the same process for every link.
What Happens If You Enter a Comment Link?
LinkedIn comment URLs contain two IDs. One belongs to the comment, and the other belongs to the post where the comment was left.
If you include a comment URL in your batch, this tool extracts the date of the parent post. It also flags that result so you know the displayed date does not belong to the comment itself.
To find the comment’s own date, use the LinkedIn Comment Date Extractor.
What Happens If a URL Is Invalid?
The tool checks every URL separately. If one URL does not contain a valid LinkedIn Post ID, that row is marked as an error.
The invalid URL does not stop the rest of the batch from being processed, and the tool does not display a made-up date.
Exporting Your Results
Once your URLs have been processed, you can export the complete results in either of these formats:
- CSV: Useful for Excel, Google Sheets, content audits, and research spreadsheets.
- JSON: Useful for developers, automation workflows, APIs, and data processing.
Both files include all the information shown in the results table.
