It looks like your query is a bit unclear. Could you please clarify what you mean by "how long ago was 9"? Are you asking about:
- How long ago was 9 o'clock (today or on a specific date)?
- How long ago was the year 9 AD or 9 BC?
- Something else related to the number 9?
Please provide a bit more detail so I can give you the most accurate and helpful answer!
