Nice step-by-step example of managing a calander dimenions in SSAS. I think a good follow-on is to develop and show a stored procedure which can dynalically generate the underlying table (the .CSV file in your example) with all the columns appropriately populated and extend the accounting principle to a 4-4-5 calendar which is common in financial analysis. Let me know if you'd like an example which I have.
