Assuming that once a number appears only once even if it remains for an hour - for example, the 5 in the hours place does not disappear and reappear at 5:00, 5:01, 5:02 and so on - it is 170 times over a 24-hour period.

The number 5 will appear 146 times in 24 hours.

There are 93 such events.
The number 5 appears 12 times on a 24-hour digital clock. It appears once in the hour (05:00, 15:00) and once in the minutes for each hour from 00 to 23 (e.g., 00:05, 01:05, ..., 23:55), resulting in 10 occurrences in the minutes. Therefore, the total is 2 (from the hours) + 10 (from the minutes) = 12.

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.

In a digital clock, the hours range from 00:00 to 23:59, totaling 24 hours. Each hour has two digits, so there are 48 total digits displayed in a day. Since the digit 7 can appear in each of these 48 digits, it can potentially appear up to 48 times in a digital clock in 24 hours.

The number 5 appears 12 times on a 24-hour digital clock. It appears once in the hour (05:00, 15:00) and once in the minutes for each hour from 00 to 23 (e.g., 00:05, 01:05, ..., 23:55), resulting in 10 occurrences in the minutes. Therefore, the total is 2 (from the hours) + 10 (from the minutes) = 12.
On an analog clock with a 12-hour face: 44 times. On a digital clock: zero. (No needles.)
