The year

This is what you see:

The months of the year.

This is what I could not
show better
and what's missing:
With the months, again the shapes are important and are predominantly oblong, much like the days of the week but marginally longer. The main differences are:

March: Slightly shorter than the previous two months

May: Square

June and July: Tendency to merge, but they are still distinct months

August: Shapeless

September: Whispy, slightly swirly, the colour is not consistent a bit like a blue sky with cirrus clouds, consequently the edges are not clear

October (my birthday month): Has no shape at all, and is defined by its absence

December: Has a degree of depth to it, in that rather than a colour it is almost a piece of silver satin material and is floaty
