When you ask the Dashboard assistant for things due before Friday, by Friday, after Friday or since Friday, the date window now follows the words: before Friday ends the day before, by or until Friday ends on it, after Friday starts the day after, and since Friday starts on it. A request with two dates, such as between Monday and Friday, is read as before.
“Due before Friday” means before Friday
The assistant reads “before”, “by”, “after” and “since” with a date exactly as written, instead of guessing.
