Moon

 When there is a moon event I see bunches of people talking about it, and so many times they say where is it..
How many will know or care about charts or fool with finding out stuff?

Look to some star, look here or there, how the weather guy gives info that people do not understand.

Everyone knows what a clock is and the lay out.
It is ok to use degrees on a map for a reference, but a clock face would be universal to all.

I assume phones have a compass. The instructions are simple, point your nose to the north 

In my imaginary interactive map, moving the slider, the parts, the rest of the moon would appear as it was moved.

In this pretend map, the clock saying point your nose north, the moon will appear at 12:17, look up about 12:12
Of course the hour hand would be removed.

 
Here is one I use if u can figure it out PE
