## How many times do clock hands Cross in 12 hours?

The key insight: In order to get back to being lined up at noon, the hands must pass each other 11 times every 12 hours. That means, if you divide 12/11, you should get the length of each interval between crossings.

## How many times clock hands coincide in a day?

Also, the hour and minute hand coincide only once between 11 and 1 o’clock i.e. at 12 o’clock. So, from both the above statements we can say that the two hands coincide exactly 11 times in a 12 hour span. times. So, the number of times the two hands coincide in a day is 22 times.
