'P' is the key

Now between the 11 o'clock spike and the 2-3 o'clock spikes, the numbers of stars that appear above drops to 1.If we consider the stars as representations as two celestial bodies [I hate this term because it sounds mystical] in the sky, the sun and the moon, the inference then becomes that at between 11 o'clock and 2-2:30 o'clock, there is only one in the sky- while the rest of the hours feature both.

There are times when the sun and moon are both visible in the sky at the same time but at night the sun is not visible in the sky and the appearance of the moon in the sky is variable.  I think it is a huge stretch to get times of sunrise and sunset from this illustration.
