I'm impressed! The extended week-year metaphor was a good summary of the more prosaic aspects of a life viewed from a distance. The line "born on a monday, murdered by sunday" caught my attention and works very nicely. The song structure was a little repetitive but i suppose it emphasized the songs theme and that ever looping "johnny doo-dah" background vocal line gave the song a dreamy dreary feel.
The audio quality was very nice and guitar was very clear and crisp. I think perhaps the lead vocals could have been a little louder but i'm not sure. There was some strange effect on the lead vocals too, they sounded slightly distorted. Not sure if it's your mic or some editing you did but perhaps some equalization might fix it.
I have no concrete helpful advice so let me end by saying good job, an enjoyable song!
