On a standard analog 12-hour clock face, how many times do the hour hand and minute hand form an exact overlap between 12:00 noon and 12:00 midnight (including the noon overlap, but excluding midnight)?
11 times
Because the hour hand continuously advances as the minute hand sweeps, the hands align every 12/11 hours (approximately 1 hour, 5 minutes, and 27 seconds). Across a 12-hour span, this event occurs exactly 11 times.
