Well, honey, let me break it down for you. The number 7 appears on a digital clock 8 times in 24 hours. You've got it showing up as the hour digit twice (7 AM and 7 PM) and as the minute digit six times (07, 17, 27, 37, 47, 57). So, grab a clock and start counting those 7s!

Why not? It separates hours from minutes. Would you prefer asterisks or what?
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.
Well, sweetheart, twenty minutes before 1pm on a digital clock is shown as 12:40. It's not rocket science, just basic math and common sense. So next time you're running late, just glance at the clock and do the math - it's not that hard, darling.

To determine how many times the number 5 appears on a digital clock in 24 hours, you can analyze each digit position (hours and minutes). The hours range from 00 to 23, where '5' appears once in the hour (05 and 15). For the minutes, '5' appears in every ten-minute interval (05, 15, 25, 35, 45, 55) for each hour, totaling 6 occurrences per hour. Combining these, '5' appears 2 times in the hour and 6 times in minutes for 24 hours, resulting in a total of 2 (from hours) + 6 x 24 (from minutes) = 146 occurrences.
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.

12 hours,
The number zero appears 48 times on a digital clock in one 24-hour period. This includes every hour from 00:00 to 09:59 (10 occurrences of '0' in the hour digits and 10 in the minutes), plus the hours from 10:00 to 23:59, where the zero only appears in the minutes (30 occurrences). Thus, the total is 10 (for hours 00 to 09) + 30 (in minutes across all hours) = 48.
8 if the hour is always 2 digits. (01:10) 57 if you go with single digit hours under 10:00 (1:01) Maybe
Analog, as opposed to digital.

Military time uses the 24 hour clock and concatenates the 2-digit hours and 2-digit minutes together to form a four-digit number.

That's the way time is written in some parts of the world.
