When did the miracle about grace hopper and the bug happend?

The famous story about Grace Hopper and the "bug" occurred on September 9, 1947. Hopper's team at the Harvard Mark II computer found a moth trapped in a relay, which they noted as the "first actual case of bug being found." This incident humorously contributed to the terminology of "debugging" in computer science. The moth was taped into the logbook, and the event has since become a well-known anecdote in tech history.
