158 In every hour of the day except 7 am and 7 pm the digit 7 appears on the clock 6 times. you take 2 hours (7am and 7pm) out of 24 hours and the rest are 22 hours. Then 22 hours multiply x 6 because in each of the 22 hours 7 appears 6 times, 22 x 6 makes 132. The remaining 2 hours from 24 are 7am and 7pm, 7 appears 13 times in each of these hours; 7:00, 7:07, 7:17, 7:27, 7:37, 7:47, 7:57. Then you do 13 x 2 because there are 2 7:00 (am and pm), you get 26. Now the total of 132 from 22 hours and 26 from the other 2 hours brings the total of 158; 132+26=158, our final answer is 158. so in 24 hours the digit 7 appears in 158 different times on a digital clock.

That depends on what time it is, and whether the clock is plugged in.
How do you find out how many times does 7 appear on a digital clock in 24 hours?
There are four digits on a digital clock. A seven will never appear in two of them. It will appear 6 times per hour (07, 17, 27, 37, 47, 57) and once each at 7 am and 7 pm, or 700 and 1700 if you're keeping military time. My best guess: 24 x 6 + 2 = 144
How many times a day does the number 1 appear on a 24 hour clock?
An hour has 60 min. Assuming the clock has only the hour and minute displayed, every hour 1 would appear at 1, 11,12,13,14,15,16,17,18,19,10,21,31,41,51. Counting 11 as once there are 15 1s in an hour. In the 24 hours, only 0,2,3,4,5,6,7,8,9,22,23 have no 1 s in them. Therefore 1 aooears 165 times in those times. As for hours 1,10,11,12,13,14,15,16,17,18,19,21, there is always a 1 in the clock. This makes 1 appear 12*60 times which is 720 times. Therefore in total, 1 appears 885 times in a digital 24 hour clock.
