The digital clock

The digital clock

We have a digital clock like the one in the photo. Throughout a full day, How many times will the time read on the clock and its reflection in the mirror be identical?

Solution

The hours at which this occurs with the following:
10:01
11:11
12:51
15:21
20:05
21:15
22:55

It must be taken into account that digital clocks do not put zero before the time of less than 10, for example, the image reflected at 2:50 (02: 5) will not be identical to the original.
