when was a LinkedIn post actually shared?
here's the formula for how to get the exact time that a LinkedIn post was shared: copy it from the embed URL and ask ChatGPT
but just in case, here's what it said
For your number:
7423962807668285440
Use this formula:
timestamp_ms = floor(LinkedIn_ID / 2^22)
Since:
2^22 = 4,194,304
Then:
7423962807668285440 / 4,194,304
= 1,770,010,663,907.119...
Drop the decimal:
timestamp_ms = 1,770,010,663,907
That means:
1,770,010,663,907 milliseconds after Jan. 1, 1970 UTC
Convert milliseconds to seconds:
1,770,010,663,907 / 1000
= 1,770,010,663.907 seconds
That converts to:
February 2, 2026 at 5:37:43.907 AM UTC
For Eastern Time on that date:
February 2, 2026 at 12:37:43.907 AM EST
The short version of the math:
LinkedIn ID ÷ 4,194,304 = Unix timestamp in milliseconds
Unix timestamp in milliseconds ÷ 1000 = Unix timestamp in seconds
Convert Unix timestamp to date/time
