• How common is this 4-4-5 (or variant) thinking in modern accounting systems? This is the first I've heard of it and I've DBA'ed behind three different fairly popular accounting systems, none of which incorporated this possibility. The assumption was always that a period was monthly.

    Then my second question is that every 5 or 6 years you'll need an extra week thrown in somewhere. Do the accountants just make a 4-5-5 in a fiscal quarter?
