I don't know how popular this is at other companies, but Intel (or at least my group) does use a week-based system for all dates. Today (December 28) would be "WW53.3". WW53 is the work week and .3 means Wednesday. Weeks start on Monday as ".1", whereas Sunday is ".0" and Saturday is ".6".

While this system should in theory make it easy to calculate the days need to complete a task, I still find myself converting to Month-Day every time. On the other hand, I don't have a clue what day of the week March 2nd is going to be, but if it's called WW9.5, then I immediately know that it's on a Friday 9 weeks from now.
