This is a piece of public art on the seafront in Southport. It certainly looks like the phases of the Moon, an idea supported by the sculpture on top of the pole above it.
But these discs on the other side cannot be phases of the Moo. They can only be the start of a solar eclipse when the shadow of the Moon starts to move across the Sun.
Art being art, you can do what you want. Perhaps the idea is that we show we are clever by understanding when the artist has chosen to twist reality....
