One thing I noticed, the calendar block content is aligned to the right instead of centered--where would be the best place to change that?
I think that may be an optical illusion.
The blocks are all left aligned but the actual content is pushed in by about 15 pixels more than the heading so that you can scan down and easily see where a new block begins.
Because the Calendar block is rather big and square, taking up the entire space allotted, it looks like it is aligned right, rather than aligned left against a slighly inset margin.
Calendars is something I'm looking at right now so it's probably best to hold off on making any changes to them yourself, though I'm not really sure I can do much about it without deviating from the original Kubrick look. Though I am trying to come up with a thinner Calendar so that might solve it.
