Antitrust decision to come on a Friday. But which one?

Here come da judge, here come da judge... The U.S. District Court of Washington announced Tuesday that Judge Thomas Penfield Jackson will issue his findings of fact in the Microsoft antitrust case "on a Friday" at 6:30 p.m. Eastern Time. But which Friday? The announcement wasn't very clear:

"The findings of fact in U.S. vs. Microsoft, State of New York, et al vs. Microsoft, will issue on a Friday evening at 6:30 p.m.," the court announced.

Microsoft and the U.S. Department of Justice (DOJ) will have two hours notice on the day that the findings are to be released
