If I smash the back of my mechanical clock with a hammer, And the hands of the clock completely stop at, Let's say 2:07, Then yes, The broken clock will be right twice a day. It will be right once when it's 2:07AM and it will be right twice when it's 2:07PM.
As long as you are not trying to refer to a digital clock, then yes, even a broken clock is right twice a day. That is simply because every day experiences the same hour twice, once in the morning (AM) and once in the afternoon and night (PM). If a clock is broke at 6:30, it is 6:30 twice a day, which makes the broken clock correct twice a day.
At its most literal level, a broken clock is certainly right at twice a day as long as it is not a digital clock, and as long is it is stopped rather than slowed. If it is a conventional numerical clock with twelve hours on the face, then it will be right twice a day.
Yes, even a broken clock is right twice a day, because there will always be a time that equals the time on the clock. For example, if an analog clock is stuck at 4:15, it will be correct when it is 4:15 AM. It will also be correct when it is 4:15 PM.
If I lock you in a room with a broken clock and say, "to get out, Knock on the door at 12 o'clock", Can you escape the room? You're clock is right twice a day so should be easy.
What if I give you a piece of paper with 12 written on it, Is that now a clock that is right twice a day? If I write every time their is in minutes of a day, Is it now a working clock?
A broken clock is right once a day/evening and once a night or early morning . Also if the clock is broken because it's slow it could be one minute behind all day hence never right . Also a digital clock says am or pm when it flashes so it'd be right just once during a 24 hour period.
In a literal interpretation of an old-style mechanical clock, yes, this aphorism is true. Digital clocks can be wrong all the time because if they lose power and then are plugged in without setting the proper time, a digital clock flashes the wrong time all the time. "A broken clock is right twice a day" only works for a mechanical clock, not a digital one. Otherwise, it's wrong all the time. Much like today's society that relies too much on technology, sometimes machines and information can be wrong all the time and not just some of the time.
