The confusing bit for me in the below code is monthname - its clearly
not the name of the month because it’s used both as an index into an
array of month names and to extract year information - what does it
contain?

What happens precisely when you click on December (what parameters are
sent with the request and what is the code that raises an exception?)

To be honest, I don’t think many people (certainly not me) want to read
though a wall of code to work out which bits are relevant and which
aren’t.
It’s up to you as question asker to do extract from your application
what
is relevant and what isn’t. It would however be a lot clearer if you
split
out some of this into helpers rather than having it all inline in your
view
