The phrase "when is 9" is ambiguous, but it commonly refers to the time 9 o'clock. In a 24-hour clock system, 9 can mean 9:00 AM (morning) or 21:00 which is 9:00 PM (evening). For example, 9:00 corresponds to 9:00 AM, which is morning time, and 21:00 corresponds to 9:00 PM in the evening.

If the question means a date such as "9th" of a month, for example, "when is 9 September," it is 45 days away from today (August 28, 2025).

If the question means something else by "when is 9," please clarify further.
