Then I'd convert to get the day of the week, another case statement to get the number of days past Thursday, do the math from the last DOM internal date, oconv the result, and grab a cup of dark roast. There are probably more efficient ways, but that's how I'd work it through my head in an interview. This is pretty much the same problem as "current week of the year" :-) Can't remember off the top of my head, but it's *extremely* easy to make an "off by one" error - I remember someone copying my Pickwiki code and getting it wrong, introducing the very error I'd fixed.
