If you mean three ones and three ones only, the the answer is twice: 1:11 a.m., and 1:11 p.pm.
If, however, your answer includes both readouts containing three or four ones, then your answer is 46 times. For both a.m. and p.m.: 11:10 1:11 11:01 11:11 11:12 11:13 11:14 11:15 11:16 11:17 11:18 11:19 11:21 11:31 11:41 11:51 10:11 and 12:11.
Of course, these answers do not hold for military time.

Oh, what a happy little question! In a 24-hour day, the digit 7 will appear 8 times on a digital clock. You can find it in times like 07:07, 17:37, and 23:57. Just imagine those sevens dancing across the clock, bringing joy to each hour.

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, 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!

The first digital alarm clock was invented in 1956 by D.E. Protzmann, an engineer at General Electric. This alarm clock featured a digital display and the ability to set specific alarm times, setting the foundation for modern digital alarm clocks.
